"I can't," she said. "Those stretchers, remember?"

"Stretchers be damned. This is destiny." He gave her his crooked smile and loped off toward the building, and as he did, she had a sudden sense of deja vu, too, a feeling that she had met him before.

Which ruled out its having happened in the future. She couldn't remember something which hadn't happened yet. It had to have been here, on this assignment. Could they have met when she was on her way to Dulwich-in the railway station as she attempted to buy a ticket? Or in Portsmouth? No, she wouldn't have forgotten those rakish good looks or that crooked smile. And it wasn't so much that he looked familiar as that he reminded her of someone.

Who? Someone in Oxford? Or on a previous assignment? She squinted, trying to remember, but she couldn't place him. Perhaps she'd only had the sensation of deja vu because of Stephen's having suggested they'd met before.

She gave up, reached for the map, and began plotting the coordinates of the V-1s which had fallen between two and five o'clock so she could plan a route back to Hendon which would avoid them. As soon as she'd finished, she mapped out a safe route back to Dulwich from Hendon. If Flight Officer Lang returned by four, and it didn't take too long to get the stretchers in Edgware, she should be able to return the way she'd come, except that she'd have to go around Maida Vale and then cut through Kilburn.

He wasn't back by four. Or half past. Or five. He'd clearly underestimated the time the meeting would take. She made a mental list of the V-1s that had fallen between five and six-no, best make it seven-and redid the route back to Hendon and then the one home, which was far longer and more complicated. She hoped she could follow it. If he wasn't here soon, she'd be driving home in the dark. And the blackout.

He finally emerged from Whitehall at a quarter past six, looking furious. "Do you know what those fools said? 'You in the RAF need to come up with more effective defensive tactics against the rocket bombs,' " he fumed, getting in and slamming the door. She started up the car and edged into traffic. "Exactly what do they suggest?" he said angrily. "It's not as though there's a pilot we can shoot, or a way to defuse the bomb en route. It's already triggered when it's launched."

She nodded absently from time to time and concentrated on getting them out of London and onto the road to Hendon. At least he'd abandoned the "Haven't I met you somewhere?" topic.

"And if we shoot them down," he raved on, "we can't control where they'll land and we may end up killing more people than would have been killed if we'd let them continue on to their target. But could I make them understand that? No."

She drove through the evening with her foot down hard on the accelerator pedal, wanting to reach Edgware Road while she could still make out landmarks, as he ranted on about how the generals knew nothing about rockets or aeroplanes.

"They demanded to know why the RAF couldn't invent some method whereby the rockets would hit woods or a meadow instead of a populated area," he told her, incensed. "But not a pasture, mind you. No, the explosion might disturb the cows!"

It was half past seven when they finally reached the turn to Hendon. By the time she dropped him off, went to Edgware, and talked the ambulance post out of the stretchers, it would almost certainly be dark.

"And you can imagine what wonderful sorts of suggestions they came up with," Stephen said. "One of the generals suggested we use nets, and another-a hundred if he was a day; I shouldn't be surprised to find he'd led the Charge of the Light Brigade-asked why we couldn't toss a rope round the rocket's nose, like roping a mare, and lead it back to France. A brilliant suggestion. Why on earth didn't I think of that?

"Sorry," he apologized. "I didn't mean to inflict my rantings on you, even though we are destined to spend the rest of our lives together. I don't suppose you gave any thought to where we should be married while I was in with that lot of fools, did you?"

"Yes," she said. "I decided we shouldn't, that wartime attachments are a bad idea. Particularly if you're going to be lassoing flying bombs."

"Well, then, I'll simply have to think of something better. And in the meantime, I'll take you to tea and-" He seemed suddenly to take in their surroundings. "We're not out of London already, are we? I intended to take you to tea at the Savoy for being so patient. Where are we exactly?"

"Home." She pulled up to the airfield gate.

"Wait," he said as she brought the Daimler to a stop. "You can't go yet." He reached to take her hand.

She avoided letting him by reaching past him for the transport form at the same time. "Have you a pen?" she asked innocently. "Oh, never mind, I have one."

He tried again. "You can't go yet. We've only just met."

"You forget, we met before," she said, filling up the transport form. "You really do need to keep your pickup lines straight, Flight Officer Lang."

"So I do," he said ruefully. "But just because I've failed in the romance department doesn't mean you should starve. You've already gone all day without food, thanks to me. Look, there's a nice little pub only a few miles from here."

She shook her head. "I must go to Edgware for those stretchers, remember?"

"I'll go with you. I'll help you load your stretchers, then we'll have dinner and work out where it was we've met before."

That was the last thing she needed. "No, I must get back. My commanding officer's extremely strict." She handed him the form to sign. "Sorry," she said, and smiled at him. "It's fate."

"All right. You win, Isolde." He signed the form, climbed out of the Daimler, and then leaned back in. "But keep in mind this is only round one. I have all sorts of techniques I haven't tried yet, which I promise you, you will not be able to resist-though I'm forced to admit you have better defenses than any girl I've ever met. Perhaps we should use you to stop the V-1s. You could turn them away with a flick of your hand or a well-timed word-"

He stopped and looked blindly at her, as if he'd suddenly remembered something.

Please don't let it be where we met, she thought. "I really must be going," she said quickly.

"What?"

"The stretchers."

"Oh. Right," he said, coming back from wherever he'd been. "Adieu, Isolde, but don't think you've seen the last of me. It's our destiny to meet again very soon. Very soon. It wouldn't surprise me if I needed a driver again tomorrow."

"I'm on duty tomorrow, and you're lassoing V-1s, remember?"

"Quite right," he said, and got that odd, looking-straight-through-her gaze again. She took the opportunity to say goodbye, pull the door shut, and drive off quickly.

"One can't escape one's destiny by driving away from it!" he called after her. "We were meant to be together, Isolde. It's fate."

I'll have to make certain I'm on duty or away from the post for the next few days, she thought, turning toward Edgware. After which he'll forget all about attempting to remember where he met me and begin calling some other girl Isolde.

She should have found a way to escape from him sooner. By the time she located Edgware's ambulance post and managed to talk them out of one lone stretcher, it was not only dark but past eight o'clock. She was in unfamiliar territory, her shuttered headlamps gave almost no light at all, and if she got lost and took the wrong road, she'd be blown up.

But she also couldn't creep along. Dulwich had had three V-1s tonight. They'd need every ambulance, and the route she'd mapped out was only good till twelve, and with the blackout, she'd have no way to look at the map. I must be home by midnight, she thought, leaning forward, both hands on the wheel, peering at the tiny area of road her headlamps illuminated. Just like Cinderella.

There wasn't enough light to see signposts by, even if there were any, which there weren't. The threat of invasion's long since over, she thought, annoyed. There's no reason for them not to have put the signposts back up.

But they hadn't, and as a result, she made two wrong turns and had to retrace her way for a tense few minutes, and it was half past twelve by the time she reached Dulwich.

The garage was empty. They've already left for the V-1 that fell at 12:20. Good, that means I can have my tea before the next one. But she'd no sooner pulled in than Fairchild and Maitland piled in beside her. "V-1 in Herne Hill, DeHavilland," Fairchild said. "Let's go."

"They've had three in the last two hours," Maitland said, "and they can't handle it all."

And for the rest of the night, Mary clambered over ruins and bandaged wounds and loaded and unloaded stretchers.

It was eight in the morning before they came home. "I heard you got stuck with my job, Triumph," Talbot said when she went into the despatch room. "Which one was it? I hope not the Octopus."

"The Octopus?"

"General Oswald. Eight hands, and cannot keep any of them to himself." Talbot shuddered. "And very quick, even though he's ancient and looks like a large toad."

"No," Mary said, laughing. "Mine was young and very good-looking. His name was Lang. Flight Officer Lang."

"Oh, Stephen." Talbot nodded wisely. "Did he convince you he'd met you somewhere before?"

"He attempted to."

"He uses that line on every FANY who drives him," Talbot said, which should have been a relief, but part of her had been secretly looking forward to the possibility of seeing him on her next assignment.

"I wouldn't set my cap for him," Talbot was saying. "He's definitely not interested in wartime attachments."

"Good," Mary said. "I'm not either. If he rings up saying he needs a driver, would you-"

"I'll see to it the Major sends Parrish."

"Thank you. Talbot, I wanted to apologize again for pushing you down. I am sorry."

"No harm done, Triumph," Talbot said, and the next day she hobbled into the common room on her crutches and kissed her on the cheek.

"What was that for?" Mary asked.

"This," Talbot said, waving a letter at her. "It came in the post this morning. Listen, 'Heard about your accident. Get better soon so we can go dancing. Signed, Sergeant Wally Wakowski,' " she read. "And in the parcel with it were two pairs of nylons! Your pushing me down was an absolute godsend, DeHavilland! As soon as my knee's healed, I'll take one-no, two-of your shifts for you."

But over the next week, the Germans increased the number of launchings till nearly two hundred and fifty V-1s were coming over every twenty-four hours, and everyone, including Talbot, went on double shifts. If Stephen had called and pretended he needed a driver, there wouldn't have been any drivers or vehicles to send. Mary and Fairchild drove the Rolls to three separate incidents, and the Major spent most of her time on the telephone attempting to talk HQ into an additional driver and/or ambulance.

But the next week, the number of V-1s arriving abruptly dropped. Mary wondered if the Germans had finally begun acting on the false information Intelligence had been feeding them and recalibrated their launchers to send the V-1s to pastures in Kent. Or perhaps Stephen had thought of a way to shoot them down. Whichever it was, the ambulance unit was able to go back to regular shifts and going to dances.

Parrish, Maitland, and Reed dragged Mary to one in Walworth. Since she now knew what a V-1 sounded like-she'd heard one on a run to St. Francis's-and since there weren't any within a twenty-mile radius of Walworth on the day of the dance, she thought she could risk it.

She was wrong. She met an American GI with exactly the same "Haven't we met somewhere before?" line as Stephen Lang, none of Stephen's charm or wit, and no dancing ability at all. She came home limping almost as badly as Talbot.

The GI rang her up every day for a week, and on Thursday, when she and Fairchild got back from their second incident of the day-one dead, five injured-Parrish met them as they came in from the garage with "Kent, there's someone waiting to see you in the common room."

"American?" she asked.

"I don't know. I'm only relaying a message from Maitland."

"I do hope it's not that GI who couldn't dance."

"Would you like me to come rescue you?" Fairchild offered.

"Yes. Wait five minutes, and then come tell me I'm needed at hospital."

"I will. Here, give me your cap."

She handed it to Fairchild, went down the corridor to the common room, and opened the door. Maitland sat perched on the arm of the sofa, swinging her legs and smiling flirtatiously at a tall young man in an RAF uniform.

It wasn't the GI. It was Stephen Lang. "Isolde," he said, smiling crookedly at her. "We meet yet again."

"What are you doing here?" she asked. "Do you need a driver?"

"No, I came to thank you."

"Thank me?"

"Yes, on behalf of the British people. And to tell you I finally remembered."

"Remembered?"

"Yes. I told you we'd met before. I finally remembered where."

Do not tell the enemy anything. Hide your food and your bicycles. Hide your maps.

1940.

London-November 1940 EILEEN LUCKED UP WILDLY AT THE SOUND OF THE SIREN. It wound up to a full-throated wail, its rising and falling notes filling the corridor outside the Hodbins' flat. "Binnie!" Eileen shouted through the door. "Where's the nearest shelter?"

She rattled the knob, but the door was locked. "Binnie, you can't stay in there!" she called through the door. "We must get to a shelter!"

Silence except for the siren, which seemed to be right there in the tenement with her, it was so loud. "Binnie! Mrs. Hodbin!" She pounded on the door with both fists. The tube station they'd come from that day she first brought the children home was over a mile away. She'd never make it in time. It would have to be a surface shelter. "Mrs. Hodbin! Wake up! Where's the nearest shelter? Mrs. Hod-"

The door flew open and Binnie shot past her down the stairs, shouting, "It's this way! Hurry!" Eileen ran after her down the three flights and past the landlady's shut door, the siren ringing in her ears. She heard the outside door bang shut, but by the time she got outside, Binnie'd vanished. "Binnie!" she called. "Dolores!"

There was no sign of her, and no one else in sight to tell her where the nearest shelter was. Eileen ran back inside and along the corridor, looking for steps that would lead down to a cellar, but she couldn't find any.

And these tenements collapse like matchsticks, she thought, panic washing over her. I must get out of here.

She ran outside and back along the street, searching for a shelter notice or an Anderson, but there were only smashed houses and head-high heaps of rubble. The planes would be here any moment. Eileen looked up at the sky, trying to spot the black dots of the approaching bombers, but she couldn't see or hear anything.

There was a thump, followed by the slither of falling dirt, and Alf leaped down from the rubble and landed at her feet. "I thought I seen you," he said. "What're you doin' 'ere?"

She was actually glad to see him. "Quick, Alf," she said, grabbing his arm. "Where's the nearest air-raid shelter?"

"What for?"

"Didn't you hear the siren?"

"Siren?" he said. "I don't 'ear no siren."

"It stopped. Is there a surface shelter near here?"

"Are you sure you 'eard a siren?" he said. "I been out 'ere ages, and I ain't 'eard nothin', 'ave I?"
