"I very much doubt it—but I feel we have to try."

"You will find, I am afraid, no diaries with carefully reasoned resumes of Mademoiselle Bergen's recollections of the incident—for she came here only for a half hour, having been discharged from the hospital, before leaving to share an apartment with a friend."

"Miss Rogers. Yes, we do know that. In fact, Miss Rogers is to meet us at Miss Bergen's apartment to see if she can remember anything the murdered girl said in that half hour—or whether the place reminds her of anything that may be of interest or of use in our inquiry."

"So. Well, I wish you luck, gentlemen, in your quest with the charming Mademoiselle Rogers..."

But the charming Mademoiselle Rogers seemed singularly reluctant to keep her appointment. "What time did Sherry tell you she'd be here?" Solo asked Illya when they had been examining the place for twenty-five minutes—and had found nothing.

"Ten o'clock. The time we arranged to get here."

"Well, that's very odd. We weren't late, so she couldn't have come and gone. When did you last see her, Illya?"

"Last night, of course. We went for a little drive after you left. We had a look at Eze village. And then I drove her home."

"Where did you leave her?"

"Outside her flat, of course," the Russian said, coloring slightly. "In the Rue Massena."

"All right, all right," Solo said, smiling. "Don't get all Slavic on me. I just thought if you had happened to stay for breakfast, it would —"

"There was nothing like that at all," Illya said stiffly—adding, with a (for him) rare flash of sarcasm: "You forget, Napoleon; I am not the chief enforcement officer!"

"Touche!" The woman's voice drawled sleepily from the door as Solo burst into laughter. Helga Grossbreitner was standing there, leaning against the doorpost. She was wearing a white linen suit with a huge-brimmed hat in lacy black straw—and she looked cool, and infinitely attractive. "Sorry I'm a few minutes late," she added, "but I came on in as the door was open...to hear my virtue—at least by implication—being impugned!"

"Come on in," Solo grinned. "Don't mind my friend: he's just a little jealous."

"Good morning, Helga," Illya said. "Do forgive me. Really, I did not in any way mean —"

"Oh, for heaven's sake!" the girl interrupted. "Don't give it a thought; we're all grown up here. If I don't mind the night porter at a man's hotel seeing me come in without luggage at one A.M., why should I object to good-humored remarks from his friend?" She paused and looked across at Solo speculatively, adding in her throatiest voice: "When are you going to ask me to dinner again, Solo?"

"Tonight," the agent replied promptly. "We're agreed that we should follow up the social life of your employees, and there's a party of them going up to Haut-des-Cagnes. I think we could do worse than tag along. We'll make up a foursome...you do know Sherry Rogers?"

"But of course. Very well. She was already on the staff at the airport when I was working here."

"Good. Which brings me to another point—the one we had been discussing when you came in: Sherry was due here at ten o'clock and now it's twenty-five to eleven. You haven't seen her?"

"I'm afraid not. I shouldn't worry though. She works in Liaison now, doesn't she? There may easily have been some panic at the aeroport."

"I suppose so. There must be plenty of alarms and excursions in your game, apart from crashes—late arrivals, reroutings, diversions and so on..."

"You're telling me!" the girl said. "Can I help in any way?"

"You can try, if you would. All we wanted to ask Sherry was to keep an eye open for anything in this apartment that she thought might throw a light—however faint—on the crash Andrea Bergen was injured in."

"But of course. Have you found anything at all yet?"

Solo and Illya admitted that they hadn't. Nor, despite the able and willing assistance of Helga, were they able to discover a single thing out of the ordinary in the apartment. Clothes, cosmetics and shoes were all neatly in place; the small kitchen held a collection of canned goods in a refrigerator, as befitted the home of a girl whose business took her away several days a week; household bills and bank statements were neatly docketed in a bureau; a bundle of unexceptional letters from a Second Officer in Swissair lived under the sachets in a handkerchief drawer. By twelve thirty, they had to confess that the apartment would yield nothing.

"I shall leave you, then," Helga said, approaching close to Solo and picking a small piece of thread from his lapel with a gloved hand. "Tonight we meet at what time?"

"Let's say seven thirty, okay?"

"Fine," Illya said. "Unless something's happened that makes it too early for Sherry. I'll have to check her apartment and the T.C.A. office to find out what's happened. I can't think what's become of her..."

But the apartment on the Rue Massena was empty and the T.C.A. bureau at the airport had heard nothing from Sherry Rogers since she went off duty at six thirty P.M. the previous day.

"She's not due on again till tomorrow morning at eight," the pretty, plump girl Illya had spoken too when first he came to the airport volunteered. " I shouldn't worry if I were you. She may have gone off for the day, you know."

"She may, certainly," Illya said to Solo afterwards. "And admittedly I don't know her well—but such behaviour would seem unlike what I have come to expect from her, you know. She definitely said she would see me at Bergen's place today."

"Well, we'll see what happens when it's time for her to show for her next duty," Solo said reasonably. "If she's not here then, you can really start to worry...in the meantime, let's just go over what we know about these automatic landing systems, okay?"

T.C.A.'s Technical Director for France saw them in his office—a small room overlooking the apron from one of the long, low buildings enclosing the company's maintenance unit at Nice. He was a slight man, with smooth dark hair and a clipped moustache, beneath which a long-stemmed pipe with a silver mouthpiece projected. For the whole time they were there, the pipe never left his mouth: it seemed jammed between his teeth, hardly moving except to wag up and down when the exigencies of the language required these to shift their position. Unlike Waverly, however, the owner of this pipe was an active smoker—obscured for much of the time that he spoke by dense clouds of tobacco fumes and surrounded by small ashtrays on which the piles of burned matches gradually mounted.

"Well, chaps," he began, "you both know the general drift now. What's the program for today? Want me to fill you in on the M-S gear?"

"Yes—if you could recap briefly, that would be a help," Solo said. "Then perhaps a few words on the implications vis-a-vis the crashes."

"Wilco," the Technical Director said. He knocked out the pipe, refilled it, sucked noisily on the mouthpiece and applied a match to the bowl. "Well, I daresay you know the R.A.E. at Bedford—the Royal Aircraft Establishment, you know—began experimenting with automatic landings soon after the war," he continued. "In 'fifty-five, the Blind Landing Unit had worked out a system for the V-bombers of the R.A.F...that's —"
