"Now, isn't that better?"

"Yes, thank you, Mary." Jenny started to cry again. "I don't know what I'd do without you."

Mary drew Jenny to her. "You'll never be without me, Jenny. I promise."

Jenny climbed into an old chair next to the fire and covered herself with a musty blanket. She pulled her feet up under herself, and after a moment the shivering stopped and she felt warm and safe. Mary was at the stove, singing softly to herself.

After a few moments the stew bubbled, filling the cottage with a wonderful smell. Jenny closed her eyes, her tired mind leaping from one pleasant sensation to the next--the warm smell of the lamb stew, the heat of the fire, the thrilling sweetness of Mary's voice. The wind and rain lashed at the window next to her head. The storm made Jenny feel wonderful to be safely inside a peaceful home. She wished her life were always like this.

A few moments later Mary brought a tray with a bowl of stew, a lump of hard bread, and a steaming mug of tea. "Sit up, Jenny," she said, but there was no response. Mary set down the tray, covered the girl with another quilt, and let her sleep.

Mary was reading next to the fire when Dogherty let himself into the cottage. She regarded him silently as he came into the room. He pointed to the chair where Jenny slept and said, "Why is she here? Her father hit her again?"

"Shhhh!" Mary hissed. "You'll wake her."

Mary rose and led him into the kitchen. She set a place for him at the table. Dogherty poured himself a mug of tea and sat down.

"What Martin Colville needs is a bit of his own medicine. And I'm just the man to give it to him."

"Please, Sean--he's half your age and twice your size."

"And what's that supposed to mean, Mary?"

"It means you could get hurt. And the last thing we need is for you to attract the attention of the police by getting in some stupid fight. Now, finish your dinner and be quiet. You'll wake the girl."

Dogherty did as he was told and resumed eating. He took a spoonful of the stew and pulled a face. "Jesus, but this food is stone cold."

"If you'd come home at a decent hour it wouldn't be. Where have you been?"

Without lifting his head from his plate, Dogherty cast Mary an icy glance through his eyebrows. "I was in the barn," he said coldly.

"Were you on the wireless, waiting for instructions from Berlin?" Mary whispered sarcastically.

"Later, woman," Sean growled.

"Don't you realize you're wasting your time out there? And risking both our necks too?"

"I said later, woman!"

"Stupid old goat!"

"That's enough, Mary!"

"Maybe one day the boys in Berlin will give you a real assignment. Then you can get rid of all the hate that's inside you and we can get on with what's left of our lives." She rose and looked at him, shaking her head. "I'm tired, Sean. I'm going to bed. Put some more wood on the fire so Jenny will be warm enough. And don't do anything to wake her. She's had a rough time of it tonight."

Mary walked upstairs to their bedroom and quietly closed the door behind her. When she was gone, Dogherty went to the cupboard and took down a bottle of Bushmills. Whisky was like gold these days, but it was a special night so he poured himself a generous measure.

"Maybe the boys in Berlin will do just that, Mary Dogherty," he said, raising his glass in a quiet toast. "In fact, maybe they already have."

LONDON.

Alfred Vicary had actually engaged in deception to get a job with military intelligence during the First War. He was twenty-one, nearing the end of his studies at Cambridge, and convinced England was foundering and in need of all the good men she could lay her hands on. He wanted nothing to do with the infantry. He knew enough of history to realize there was no glory in it, only boredom, misery, and very likely death or serious injury.

His best friend, a brilliant philosophy student named Brendan Evans, arrived at the perfect solution. Brendan had heard the army was starting up something called the Intelligence Corps. The only qualifications were fluent German and French, extensive travel throughout Europe, the ability to ride and repair a motorbike, and perfect eyesight. Brendan had contacted the War Office and made appointments for them the next morning.

Vicary was despondent; he did not meet the qualifications. He had fluent if uninspired German, passable French, and he had traveled broadly across Europe, including inside Germany. But he had no idea how to ride a motorbike--indeed, the contraption scared the daylights out of him--and his eyesight was atrocious.

Brendan Evans was everything Vicary was not: tall, fair, strikingly handsome, possessed of a boyish lust for adventure and more women than he knew what to do with. They had one trait in common, flawless memories.

Vicary conceived his plan.

That evening, in the cool twilight of August, Brendan taught him to ride a motorcycle on a deserted patch of road in the Fens. Vicary nearly killed them both several times, but by the end of the night he was roaring along the pathways, experiencing a thrill and a recklessness he had never before felt. The following morning, during the train ride from Cambridge to London, Brendan drilled him relentlessly on the anatomy of motorbikes.

When they arrived in London, Brendan went into the War Office while Vicary waited outside in the warm sunshine. He emerged an hour later, grinning broadly. "I'm in," Brendan said. "Now, it's your turn. Listen carefully." He then proceeded to read back the entire eye chart used for the vision test, even the hopelessly tiny characters at the bottom.

Vicary removed his spectacles, handed them to Brendan, and walked like a blind man into the dark, forbidding building. He passed with flying colors--he made only one mistake, transposing a B B for a for a D, D, but that was Brendan's fault, not his. Vicary was immediately commissioned as a second lieutenant in the motorcyclist section of the Intelligence Corps, given a warrant for his uniform and kit, and ordered to cut his hair, which had grown long and curly over the summer. The following day he was ordered to Euston Station to collect his motorbike, a shiny new Rudge model packed in a wooden crate. A week later Brendan and Vicary boarded a troop-ship along with their motorbikes and sailed for France. but that was Brendan's fault, not his.

A week later Brendan and Vicary boarded a troop-ship along with their motorbikes and sailed for France.

It was all so simple then. Agents slipped behind enemy lines, counted troops, watched the railways. They even used carrier pigeons to deliver secret messages. Now it was more complex, a duel of wits over the wireless that required immense concentration and attention to detail.

Double Cross. . . .

Karl Becker was a perfect example. He was sent by Canaris to England during the heady days of 1940, when invasion seemed certain. Becker, posing as a Swiss businessman, set himself up in suitable style in Kensington and began collecting every questionable secret he could lay his hands on. It was Becker's use of counterfeit sterling that set Vicary onto him, and within a matter of weeks he had been spun into MI5's web. Vicary, with the help of the watchers, went everywhere Becker went: to the parties where he traded in gossip and drank himself stiff on black-market champagne; to his meetings with live agents; to his dead drops; to his bedroom, where he brought his women, his men, his children, and only God knew what else. After a month Vicary brought down the hammer. He arrested Becker--pulled him from the arms of a young girl he had kept locked away and drunk on champagne--and rolled up an entire network of German agents.

Next came the tricky part. Instead of hanging Becker, Vicary turned him--convinced him to go to work for MI5 as a double agent. The following night Becker, from his prison cell, turned on his radio and tapped out a coded recognition signal to the operator in Hamburg. The operator asked him to stay on the air for instructions from his Abwehr control officer in Berlin, who ordered Becker to determine the exact location and size of an RAF fighter base in Kent. Becker confirmed the message and signed off.

But it was Vicary who went to the airfield the next day. He could have called the RAF, obtained the coordinates for the base, and sent them to the Abwehr, but it wouldn't be so easy for a spy. To make the message appear authentic, Vicary went about reconnoitering the air base just the way a spy would do it. He took the train from London and, because of delays, didn't arrive in the area until dusk. A military policeman harassed him on a hillside outside the base and asked him for his identification. Vicary could see the air base on the flats below, the same perspective from which a spy might see it. He saw a cluster of Nissen huts and a few aircraft along the grassy runway. During his return to London, Vicary composed a brief report on what he had seen. He noted that the light had been poor because the trains were late and said he had been prevented from getting too close by an MP. That night Vicary forced Becker to send the report with his own hand, for each spy had his own distinctive keying style, known as a fist, fist, that German radio operators could recognize. Hamburg congratulated him and signed off. that German radio operators could recognize. Hamburg congratulated him and signed off.

Vicary then contacted the RAF and explained the situation. The real Spitfires were removed to another field, the personnel evacuated, and several badly damaged fighters were fueled and placed along the runway. That night the Luftwaffe came. The dummy planes exploded into fireballs; certainly the crews of the Heinkel bombers thought they had scored a direct hit. The next day the Abwehr asked Becker to return to Kent to assess the damage. Again, it was Vicary who went, gathered a report on what he could see, and forced Becker to send it.

The Abwehr was ecstatic. Becker was a star, a super-spy, and all it had cost the RAF was a day patching up the runway and carting off the charred skeletons of the Spitfires.

So impressed were Becker's controllers, they asked him to recruit more agents, which he did--actually, which Vicary did. By the end of 1940, Karl Becker had a ring of a dozen agents working for him, some reporting to him, some reporting directly to Hamburg. All were fictitious, products of Vicary's imagination. Vicary tended to every aspect of their lives: they fell in love, they had affairs, they complained about money, they lost houses and friends in the blitz. Vicary even allowed himself to arrest a couple of them; no network operating on enemy soil was foolproof, and the Abwehr would never believe none of their agents had been lost. It was mind-bending, tedious work, requiring attention to the most trivial detail; Vicary found it exhilarating and loved every minute of it.

The lift was on the blink again, so Vicary had to take the stairs from Boothby's lair down to Registry. Opening the door he was struck by the smell of the place: decaying paper, dust, tangy mildew from the damp creeping through the cellar walls. It reminded him of the library at the university. There were files on open shelves, files in the file cabinets, files stacked on the cold stone floor, piles of paper waiting to ripen into files. A trio of pretty girls--the shakedown night staff--moved quietly about, speaking a language of inventory Vicary could not understand. The girls--known as Registry Queens in the lexicon of the place--looked strangely out of place amid the paper and the gloom. He half expected to turn a corner and spot a pair of monks reading an ancient manuscript by candlelight.

He shivered. God, but the place was cold as a crypt. He wished he had worn a sweater or brought something warm to drink. It was all here--the entire secret history of the service. Vicary, wandering the stacks, was struck by the thought that long after he left MI5 there would be an eternal record of his every action. He wasn't certain if he found the thought comforting or sickening.

Vicary thought of Boothby's disparaging remarks about him, and a cold shiver of anger passed over him. Vicary was a damned good Double Cross officer, even Boothby couldn't deny that. He was convinced it was his training as a historian that suited him so perfectly to the work. Often, a historian must engage in conjecture--taking a series of small inconclusive clues and reaching a reasonable inference. Double Cross was very much like engaging in conjecture, only in reverse. It was the job of the Double Cross officer to provide the Germans with small inconclusive clues so they could arrive at desired conclusions. The officer had to be careful and meticulous in the clues he revealed. They had to be a careful blend of fact and fiction, of truth and painstakingly veiled lies. Vicary's bogus spies had to work very hard for their information. The intelligence had to be fed to the Germans in small, sometimes meaningless bites. It had to be consistent with the spy's cover identity. A lorry driver from Bristol, for example, could not be expected to come into possession of stolen documents in London. And no piece of intelligence could ever seem too good to be true, for information too easily obtained is easily discarded.

The files on Abwehr personnel were stored on open floor-to-ceiling shelves in a smaller room at the far end of the floor. The V V 's started on a bottom shelf, then jumped to a top one. Vicary had to get down on all fours and tilt his neck sideways, as if he were looking for a lost valuable beneath a piece of furniture. Damn! The file was on the top shelf, of course. He struggled to his feet and, craning his neck, peered at the files over his half-moon reading glasses. Bloody hopeless. The files were six feet above him, too far to read the names--Boothby's revenge on all those who had not attained regulation department height. 's started on a bottom shelf, then jumped to a top one.

The files were six feet above him, too far to read the names--Boothby's revenge on all those who had not attained regulation department height.

One of the Registry Queens found him gazing upward and said she would bring him a library ladder. "Claymore tried to use a chair last week and nearly broke his neck," she sang, returning a moment later, dragging the ladder. She took another look at Vicary, smiled as if he were a daft uncle, and offered to get the file for him. Vicary assured her he could manage.

He climbed the ladder and, using his forefinger as a probe, picked through the files. He found a manila folder with a red tab: VOGEL, KURT--ABWEHR BERLIN. He pulled it down, opened it, and looked inside.

Vogel's file was empty.

A month after he arrived at MI5, Vicary had been surprised to find Nicholas Jago working there too. Jago had been head archivist at University College and was recruited by MI5 the same week as Vicary. He was assigned to Registry and ordered to impose some discipline on the sometimes fickle memory of the department. Jago, like Registry itself, was dusty and irritable and difficult to use. But once past the rough exterior he could be kind and generous, bubbling with valuable information. Jago had one other valuable skill: he knew how to lose a file as well as find one.

Despite the late hour, Vicary found Jago working at his desk in his cramped, glass-enclosed office. Unlike the file rooms it was a sanctuary of neatness and order. When Vicary rapped his knuckle against the windowed door, Jago looked up, smiled, and waved him in. Vicary noticed the smile did not extend to his eyes. He looked exhausted; Jago lived lived in this place. There was something else: in 1940 his wife had been killed in the blitz. Her death had left him shattered. He had taken a personal oath to defeat the Nazis--not with the gun, with organization and precision. in this place. There was something else: in 1940 his wife had been killed in the blitz. Her death had left him shattered. He had taken a personal oath to defeat the Nazis--not with the gun, with organization and precision.

Vicary sat down and refused Jago's offer of tea--"real stuff I hoarded before the war," he said excitedly. Not like the atrocious wartime tobacco he was stuffing into the bowl of his pipe and setting ablaze with a match. The vile smoke smelled of burning leaves, and it hung between them in a pall while they swapped banalities about returning to the university when the job was done.

Vicary signaled he wanted to get down to business by gently clearing his throat. "I'm looking for a file on a rather obscure Abwehr officer," Vicary said. "I was surprised to find it's missing. The exterior cover is on the shelf, but the contents are gone."

"What's the name?" Jago asked.

"Kurt Vogel."

Jago's face darkened. "Christ! Let me take a look for it. Wait here, Alfred. I'll just be a moment."

"I'll come with you," Vicary said. "Maybe I can help."

"No, no," Jago insisted. "I wouldn't hear of it. I don't help you find spies, you don't help me find files." He laughed at his own joke. "Stay here. Make yourself comfortable. I'll just be a moment."

That's the second time you've said that, Vicary thought: I'll just be a moment. I'll just be a moment. Vicary knew that Jago had become obsessive about his files, but one missing dossier on an Abwehr officer was not cause for a departmental emergency. Files were misplaced and mistakenly discarded all the time. Once Boothby sounded a red alert after losing an entire briefcase filled with important files. Department legend said they had been found a week later at the flat of his mistress.

Department legend said they had been found a week later at the flat of his mistress.

Jago rushed back into the office a moment later, a cloud of the vile pipe smoke floating behind him like steam from a locomotive. He handed Vicary the file and sat down behind his desk.

"Just as I thought," Jago said, absurdly proud of himself. "It was right there on the shelf. One of the girls must have placed it in the wrong folder. Happens all the time."

Vicary listened to the dubious excuse and frowned. "Interesting--never happened to me before."

"Well, maybe you're just lucky. We handle thousands of files a week down here. We could use more staff. I've taken it up with the director-general, but he says we've used up our allotment and we can't have any more."

Jago's pipe had gone dead and he was making a vast show of relighting it. Vicary's eyes teared as the little chamber of an office filled with smoke again. Nicholas Jago was a thoroughly good and honest man, but Vicary didn't believe a word of his story. He believed the file had been pulled by someone recently and hadn't made its way back to the shelf. And the someone who pulled it must have been someone damned important, judging by the look on Jago's face when Vicary had asked for it.

Vicary used the file to wave a clear patch in the cloud of smoke. "Who had Vogel's file last?"

"Come on, Alfred, you know I can't tell you that."

It was the truth. Mere mortals like Vicary had to sign out files. Records were kept on who pulled what files and when. Only the Registry staff and department heads had access to those records. A handful of very senior officers could get files without signing them out. Vicary suspected Vogel's file had been pulled by one of those officers.

"All I have to do is ask Boothby for a chit to see the access list and he'll give it to me," Vicary said. "Why don't you let me see it now and save me the time?"

"He might, he might not."

"What do you mean by that, Nicholas?"

"Listen, old man, the last thing I want to do is get between you and Boothby again." Jago was busying himself with the pipe again--stuffing the bowl, digging a match out of the matchbox. He stuck the thing between his clenched teeth so the bowl bounced while he spoke. "Talk to Boothby. If he says you can see the access list, it's all yours."

Vicary left him sitting in his smoky glass chamber, trying to set fire to his cheap tobacco, his match flaring with every drag on the pipe. Taking one last glance at him as he walked away with Vogel's file, he thought Jago looked like a lighthouse on a foggy point.

Vicary stopped at the canteen on the way back up to his office. He couldn't remember when he had last eaten. His hunger was a dull ache. He no longer craved fine food. Eating had become a practical undertaking, something to be done out of necessity, not pleasure. Like walking London at night--do it quickly, try not to get hurt. He remembered the afternoon in May 1940 when they had come for him. Mr. Ashworth delivered two nice lamb chops to your house a short time ago Mr. Ashworth delivered two nice lamb chops to your house a short time ago. . . . Such a waste of precious time.

It was late and the selection was worse than usual: a chunk of brown bread, some suspect cheese, a bubbling cauldron of brown liquid. Someone had crossed out the words Beef broth Beef broth on the menu and written on the menu and written Stone soup. Stone soup. Vicary passed on the cheese and sniffed at the broth. It seemed harmless enough. He cautiously ladled himself out a bowl. The bread was as hard as the cutting board. Vicary hacked off a hunk with the dull knife. Using Vogel's file as a service tray, he picked his way through the tables and chairs. John Masterman sat stooped over a volume of Latin. A pair of famous lawyers sat at a corner table, rearguing an old courtroom duel. A popular writer of crime novels was scribbling in a battered notebook. Vicary shook his head. MI5 had recruited a remarkable array of talent. Vicary passed on the cheese and sniffed at the broth. It seemed harmless enough. He cautiously ladled himself out a bowl.

A popular writer of crime novels was scribbling in a battered notebook. Vicary shook his head. MI5 had recruited a remarkable array of talent.

He walked carefully up the stairs, the bowl of broth balanced precariously on the file. The last thing he needed was to soil the dossier. Jago had written countless irate memoranda imploring case officers to take better care of the files.

What's the name?

Kurt Vogel.

Christ! Let me take a look for it.

Something about it just wasn't right--that Vicary knew. Better not to force it. Better to set it aside and let his subconscious turn over the pieces.

He set the file and the soup down on his desk and switched on the lamp. He read the file through once while he sipped at the soup. It tasted like a boiled leather boot. Salt was one of the few spices the cooks had in plentiful supply, and they had used it generously. By the time he finished reading the file the second time, he had a desert thirst and his fingers were beginning to swell.

Vicary looked up and said, "Harry, I think we have a problem."

Harry Dalton, who had drifted off to sleep at his desk in the common area outside Vicary's office, got to his feet and came inside. They were a dubious pairing, jokingly referred to inside the department as Muscle & Brains, Ltd. Harry was tall and athletic, sharp-suited, with thickly brilliantined black hair, intelligent blue eyes, and a ready all-purpose smile. Before the war he was Detective-Inspector Harry Dalton of the Metropolitan Police Department's elite murder squad. He was born and raised in Battersea and still had a trace of working-class south London in his soft pleasant voice.

"He's got brains, that's for certain," Vicary said. "Look at this: doctorate of law from Leipzig University, studied under Heller and Rosenberg. Doesn't sound like your typical Nazi to me. The Nazis perverted the laws of Germany. Someone with an education like that couldn't be too thrilled about them. Then in 1935 he suddenly decides to forsake the law and go to work for Canaris as his personal attorney, a sort of in-house counsel for the Abwehr? I don't believe that. I think he's a spy, and this business about being Canaris's legal adviser is just another layer of cover."

Vicary was flipping through the file again.

"You have a theory?" Harry asked.

"Three theories, actually."
