"Here," Auger said, thrusting some notes at him. "Keep the change."

A minute later she was inside the iron and gla.s.s vault of the station, looking for the ticket office. The platform swarmed with travellers, jostling and orbiting each other like a ma.s.s of grey bees, each knowing their mission and utterly oblivious to anyone else. Beyond, the trains waited with snorting impatience, pushing quills of white steam up towards the roof. Even as she watched, a sleeper drew out, headed for Munich or Vienna or some other city even further into the European night. Its red tail light spilled blood on to the polished surfaces of the rails.

First things first. Auger found the ticket office and was relieved to see that the line for international connections was much shorter than the others. She had already vowed that if there was no accommodation left on the night train, then she would simply board it and argue her case later. Bribery was always an option, as was theft. But there were still couchettes available on the seven o'clock service -later than she would have liked, but better than nothing.

She handed over the money, the ticket clerk barely batting an eyelid at her blackened hands and dirt-encrusted fingernails. She imagined that the clerks had learned not to bat their eyelids at many things.

"What platform?" she asked. The clerk told her, also warning her that the train would not be ready for boarding until thirty minutes before departure.

That gave her nearly an hour before she could get on the train. She used the first twenty minutes of that period finding a ladies' washroom and attending as best she could to the dirt and damage she had sustained in the tunnel. By the time she was done, she had turned the bar of carbolic soap black and the basin looked as if it had been used by a party of miners after a shift down the pit. But she looked and felt human again, and by the time she had changed into more of Greta's clothes, stuffing her own soiled and ripped garments back into the bag, she had also begun to feel that she was less likely to be recognised. With over an hour remaining before the train was due to depart, Auger was tempted to leave the station entirely to seek the comparative anonymity of a local bistro or bra.s.serie. She had not eaten since breakfast, and her hunger was beginning to catch up with her. But she knew that if she left Gare du Nord, she might not have the courage to return, no matter how much money she had spent on the couchette. Instead, she settled on a restaurant inside the station, and within its mirrored labyrinth of an interior she found a secluded booth where she could watch whoever came and went without being the object of attention herself. She ordered a sandwich and a gla.s.s of wine, and willed the hands on the restaurant clock to whirl around to half-past six.

Through the gla.s.s doors of the restaurant, far across the concourse, she saw a man in a grey raincoat and hat pause at a newspaper concession. As he fiddled in a pocket for change, he looked around, like a tourist taking in the station for the first time. After making his purchase, he turned from the concession stand, pushing owlish gla.s.ses back up his nose. He flicked open the paper and started reading. It wasn't Floyd.

Auger's food arrived. She sniffed the wine, drank half the gla.s.s down in short order and for the first time since waking that day permitted a temporary calm to flow through her. In a little while she would be on the overnight train, safe in her berth. It was no more dangerous than staying in Paris-less so, perhaps, since she would be putting increasing distance between herself and the war babies. Once in Berlin, she would follow up on the address for the Berlin manufacturing firm and see where that led. At no point would she put herself in harm's way, or do anything that she felt might expose her true ident.i.ty. Even if all she came back with was a description of the firm's premises, she would have achieved something useful. Caliskan would undoubtedly rebuke her for exceeding the terms of her mission, while expressing private grat.i.tude for what she had done. And even as she followed up Susan White's aborted line of enquiry, Auger would be observing more of this world than she ever could if she stayed locked up in a Paris hotel room, cowering from every shadow.

Another man in a raincoat pushed open the doors to the restaurant. He was hatless, but for a moment- as the steam from the coffee machine blocked her view-it could also have been Floyd. But the man had no sooner stepped inside than a slender woman in a body-hugging emerald dress stood up from her table, and the two of them kissed like the illicit lovers Auger was sure they were. The man had a gift for the woman, which she opened with a gasp of nervous delight. It was some kind of jewellery. He ordered a drink and the two of them sat there holding hands for ten minutes, whereupon the man kissed her goodbye and vanished back into the bustle of the station. A minute later, Auger heard the whistle of a departing train, and knew with absolute certainty that the man was on it, heading back to his provincial house and his provincial family, that ten-minute a.s.signation as much a routine as brushing his teeth and kissing his wife goodbye each morning. For a dizzying instant, the people around her suddenly felt as real as anyone she had ever known, and it was only by a supreme effort of will that she was able to reduce their lives once again to something more manageable, like an echo or afterimage.

Auger checked her watch. In a few minutes she would be able to board the train and find her couchette. An hour from now she would be halfway to the French border, and by the time she awoke she would, for better or worse, have arrived in Berlin. She signalled for her bill, then began gathering her things. Perhaps it was the wine, but now she felt a steely resolve to complete the investigation Susan White had begun.

A waiter in a white c.u.mmerbund brought the bill. Auger dug through her coinage, satisfied when she found enough to include a reasonable tip. Smiling, she slid the money towards the waiter and made ready to leave, deciding she would be better off not finishing the wine.

It was then that she saw the children.

There were two of them, standing quite still next to each other in the middle of the concourse. The boy held the lank thread of a yo-yo, while the girl carried a toy animal that looked as if it had been rescued from a dustbin. The boy wore a red T-shirt and shorts, with white socks and buckled black shoes, the girl a dirty yellow dress and the same kind of shoes. It was only when one really looked at them that it became clear that they were not really children at all, but ghouls in the rough shape of children. The rain had distorted their make-up, making it sag and run. Travellers pushed around them, but gave the children a certain distance, perhaps without realising it.

Auger lost sight of the diminutive figures as a group of people blocked her view. She swallowed and tried to keep her nerve. Her imagination might be running ahead of her. They might just have been street urchins, after all.

When the group dispersed, the two children were gone.

She closed her eyes in relief, then quickly finished what remained of the wine. She told herself to get up and leave the restaurant, while the train was still waiting. There was no point reacting in horror every time a child walked by. Paris was full of strange little boys and girls, and they were not all out to kill her.

A couple of businessmen moved away from the front of the restaurant. There were the children again: standing perfectly still, but now much closer to the door. They were not looking at her, but they were regarding something or someone with the unblinking attention of snakes. Another group of pa.s.sers-by obstructed her view, and when they had moved away, the children were even closer, their attention clearly directed at the restaurant itself. A moment ago she might have stood a chance of leaving without them noticing her, but now she was trapped.

Auger looked down at the remains of her sandwich, then pretended to read the menu again. The last thing she wanted to be seen to be doing was taking an unusual interest in what was going on outside. The children might not necessarily know exactly what she looked like any more, after all.

When she risked another glance towards the door, only the little girl was standing outside. The boy was now inside the restaurant, waiting by the illuminated counter where freshly made cakes were laid out for inspection. A pair of flies hovered near the boy, seemingly more interested in him than in the sugary delicacies.

Auger sank down into the booth. She had a clear line of sight to the boy, but he did not appear to have noticed her yet. Staying rooted to the same spot of floor, his head was rotating in a slow and level arc, like a tracking surveillance camera. She was tempted to move behind the cover of another of the mirrored screens separating the booths, but knew that the boy would probably notice. His eyes blinked but rarely, as if he had to remind himself each time. In a few seconds he would be looking directly at her unless she moved. Belatedly, she remembered that she was carrying two weapons: the automatic and the sleek gun that she had taken from the war baby in the tunnel. The knowledge gave her a flicker of confidence, but she soon dismissed any thought of using the guns. The children were probably armed themselves, and there might be more of them than the two she had noticed. Besides, even if she dealt with the children, she would stand little chance of leaving this busy station without being apprehended and arrested.

The boy's gaze had almost speared her. Frozen, she knew that her only hope lay in his failing to recognise her. Perhaps he would not, given her state of dishevelment and the fact that she was wearing someone else's clothes. She had no sooner clutched at this straw than she forced herself to dismiss it, for the boy was obviously looking for her specifically, and would not be fooled by a few superficial changes.

Auger's hand reached under the table for the automatic. Perhaps she would have to use it after all, regardless of the consequences.

The boy looked at-or more exactly through-her. She felt as if a searchlight beam had swept over her. The smooth rotation of his head continued, taking his attention beyond her. His head had turned through nearly ninety degrees from the starting position of its arc and showed every indication of continuing, impossible though such a movement would be for a human child. Auger wondered how long it would be before someone else spotted the peculiar little boy, but as far as she could tell the other people in the restaurant had noticed nothing out of the ordinary.

Then the child's head stopped and reversed, until the boy was looking towards her again. This time she felt the focus of his attention: he wasn't just looking in her direction, but was concentrating on the booth in which she was sitting. A barely recognisable change came across the powdered and smudged mask of his face, the tiniest widening of his mouth suggesting a smile of triumph or gluttony.

The boy's head snapped back towards the restaurant door and he opened his mouth to emit a single shriek. To any casual bystander, it would have sounded like a meaningless, yodel-like exclamation- evidence, perhaps, of idiocy on the child's part. But Auger knew that the shriek was crammed with sonic information, and that the other child was fully capable of deciphering it.

Stiff-kneed, like a puppet that wasn't being worked properly, the boy began to walk towards Auger's booth. She tried not to react in any way, keeping her own attention on the clock, hoping that the boy would have second thoughts before he reached her. He had pocketed the yo-yo and now something gleamed in his hand, mirror-bright and sharp as gla.s.s.

A hand touched the boy's shoulder. The boy yanked his head towards the adult in fury and incomprehension, his face twisted into a scowl that served only to crack and dislodge the remaining scabs of make-up covering up his true appearance. The hand emerged from the dark sleeve of a suit belonging to one of the waiters. The man was large even amongst adults, and towered over the boy. Still trying not to look directly at what was happening, Auger saw the man crease himself down the middle to bring his moustached, fat-necked head into proximity with the boy. The man started to say something, his lips working silently across the room, and then there was a quick flash of silver and the waiter stepped back from the boy with a look of mild surprise on his face, as if the child had sworn at him in an ingenious and adult way.

The man crashed back into the display of cakes, sprawling across the zinc-topped surface. In the pure white of his c.u.mmerbund was a little spreading star of red, where he had been stabbed. The man dabbed at the wound with his fingers and lifted their reddened tips to his face. He started to say something, the words jamming in his throat. Around him, some of the other diners dropped their cutlery and started talking in alarmed voices. A man shouted something and a woman screamed. A gla.s.s went crashing to the floor.

The boy had gone.

Within a few seconds, complete pandemonium had erupted around the stabbed waiter. Auger could see only the backs of do-gooders crowding around him. Another waiter yelled into the restaurant telephone, while a third jogged across the concourse to fetch help. The scene had already begun to attract the attention of onlookers outside, waiting for trains. Some kind of railway official-a remarkably similar-looking individual to the man Floyd had bribed that afternoon-began to stroll towards the door and, seeing the size of the commotion, broke into a wheezing, heavy-bellied lope. Someone blew three sharp blasts on a whistle.

Auger stood up, gathering her things. Were the children still out there, waiting for her? There was no way of telling. What she did know was that she did not want to be here when-as seemed certain-the police arrived and began taking the names and addresses of witnesses. She could not afford to miss that Berlin train, and she certainly could not afford to fall into the machinery of the law. What if the station official at Cardinal Lemoine had decided to talk to his superiors after all?

She wiped crumbs from her lips and judged her moment, excusing herself past the concerned onlookers crowding around the wounded man. She might as well have been made of smoke for all the attention anyone paid her. Pausing at the door, she looked left and right along the concourse, but there was no sign of the two children. All she could hope was that they had decided to leave the station before too many witnesses described a vicious little boy with a knife. As quickly as she could without attracting unwanted attention, Auger made her way to the departures board and double-checked the platform for the overnight train to Berlin. It was waiting now: a long chain of dark-green carriages, with a black steam engine simmering at the far end. Along the length of the train, the station staff were still preparing it: there were trolleys loaded with linen, food and drink, and men in uniforms were coming and going through the open doors, barking to each other in heavily accented French. A station official shook his head at Auger as she tried to step on to the platform, tapping his watch with a finger.

"Please, monsieur," Auger said. In the distance she heard the sc.r.a.ping whine of police sirens, nearing the railway station. "I need to be on that train."

It might have been the worst thing she could have said, if the man got it into his head that she was running from the authorities. "Mademoiselle," he said apologetically, "Five more minutes, then you can board."

Auger dropped her bags and dug into what was left of her money. "Take this," she said, offering him ten francs. "It's a bribe."

The man pursed his lips, looking her over. The sirens sounded very near now. Out of the corner of her eye, she saw people still cramming around the entrance to the restaurant.

"Twenty," he said. "Then you can find your couchette."

"For twenty you can help me find it," Auger replied archly.

The man seemed to find this an acceptable compromise, pocketing the additional ten-franc note and leading her down the length of two carriages until he found one that corresponded to the number on her ticket. Inside, everything was clean, bright and narrow. The man found her compartment and pushed open the door. There was a key on the inside of the door, which he removed and gave to Auger.

"Thank you," she said.

The man inclined his head, then left her alone. There were two bunks in the sleeping compartment, but she had paid to have the entire cabin to herself. There was a neat aluminised basin and tap in one corner, plus a tiny cupboard and a small fold-down writing desk and stool. The walls were varnished wood with recessed electric lights. There was a communication cord and pull-down fabric blind, and a faded monochrome photograph of some cathedral she didn't recognise.

Auger slid the window down, letting in the noises of the station. Amidst the clatter of slamming doors, arriving and departing trains and announcements over the Tannoy, it was difficult to be sure, but she did not think she could hear the sirens now. Did that mean the police had pa.s.sed the station by entirely, on some other errand? She looked at her watch again, willing the hands to slide around to departure time.

From somewhere nearby, outside the train, she heard a heated exchange of voices. Slowly, Auger inched her head out of the window so that she could look back along the length of the train. There was the man she had bribed, gesticulating and arguing with a pair of uniformed policemen. Angrily, they pushed past the man and began strolling along the line of carriages. They were walking very slowly, stopping at each compartment window. One of the men had a ribbed-metal flashlight, which he was shining into each compartment, tapping on the gla.s.s at the same time. The station official trailed behind them, muttering under his breath.

Auger forced herself to breathe again. Slowly, slowly, she moved her head back inside and slid the window up to its closed position. There was time to get out of the compartment, but what if another policeman was moving along the inside of the train, covering that line of escape?

The voices of the two officers came closer. She heard them tapping on the gla.s.s two or three compartments down from hers. It was much louder now. There was barely time to move her things out of sight, and certainly no time to think of hiding herself. All she could do was act as naturally as possible. Auger dragged the blind down halfway and sat, waiting.

There was a knock on the interior door. She held her breath, silently willing whoever it was to go away.

The person knocked again. A low, urgent voice whispered, "Auger?"

It was Floyd. It was Floyd and she really did not need this.

Keeping her own voice low, she pressed her lips to the door. "Go away. I said I didn't want to see you

again."

"And I think we have unfinished business."

"In your imagination, perhaps."

"Let me in. There's something I have to tell you. Something I think might make you change your mind."

"Nothing you could say or do, Wendell..." But she silenced herself. The officers outside were now very

close to her compartment.

"I kept something back," Floyd said.

"What do you mean?" she hissed.

"From that box of papers. Figured it might be useful to have some bargaining strength."

"I got everything I needed from those papers already, Floyd."

"Is that why you're on your way to Germany? Because you already have all the answers?"

"Don't overestimate yourself," Auger said.

"What happened back at the restaurant?"

She saw no harm in telling him. "One of those child-things. It stabbed a waiter."

"The kid was looking for you?"

What was the point of lying now? "Give yourself a pat on the back. Now quit while you're ahead and

leave me alone."

"The policemen outside think you might have had something to do with it. You fled the scene, after all.

Innocent witnesses don't do that. Ask Custine. He'll tell you all about it."

"I'm sorry about Custine," she said. "I'm sorry he got involved in all of this and I hope you can find a way to help him. But it isn't my problem. Your entire little world isn't my problem."

"You know what really hurts? The way you almost sound as if you mean that."

"I do mean it," she said fiercely. "Now go away."

"Those policemen aren't going to let you ride this train anywhere."

She heard the whistle and snort of a departing train. But it wasn't the one she was sitting in. "I'll deal with them."

"Like you dealt with me this afternoon? You weren't going to use that gun, Verity. I could see it in your eyes."

"Then you're an exceptionally poor judge of character. I would have used it, if necessary."

"But you wouldn't have enjoyed it."

There was a hard knock on the gla.s.s. A voice with a Parisian accent said sharply, "Open the window."

She slid the blind up and pulled on the leather strap that lowered the gla.s.s. "Do you want to see my ticket?"

"Just your identification," said one of the officers standing outside.

"Here." Auger slid the papers through the gap in the window. "Is something the matter? I wasn't expecting to have my papers examined until later."

"Is there anyone else in that compartment with you?"

"I think I'd have noticed."

"I heard you talking."

With a casualness that surprised her, Auger said, "I was reciting a list of the things I have to do in

Berlin."

The man made an equivocal noise. "You're on the train alone, before anyone else. Why were you in such a hurry to get aboard?"

"Because I'm tired and I don't want to have to squabble with anyone else over who has the ticket for this
