"Why?" inquired Miss Glenn practically.
"How should I know?" Morgan demanded, with some asperity. His imagination had been working on opulent ballrooms full of tiaras and red shirt-ribbons; and sinister whiskery strangers smoking cigarettes round the corners of pillars. "Maybe it was accident, maybe Film-Flam is a professional diplomatic crook who dashes about from capital to capital and hopes for the best. Anyway, you've got to admit it was somebody who'd been in Washington and heard all about the indiscretion… Righto, then. He's abandoned the idea, but all the same he happens to be travelling aboard the same boat as Curt. If you looked at the passenger-list, Curt, would you recognise the name of anybody who'd been at your uncle's house that night?"
Warren shook his head.
"There were millions of 'em and I didn't know anybody. No, that won't work… But you mean this. You mean that this bird (after abandoning the idea) overhears that cable in the wireless-room, tumbles to it before I do, and takes a long chance on stealing it before I've got time to realise what I'm carrying?"
"He'd have to work fast, man. Otherwise, as soon as you knew you'd chuck it overboard. And here's another thing," crowed Morgan, stabbing his finger into his palm as the idea grew on him. "The field of search isn't as wide as you'd think at first. Again this is only a theory, but look here! — isn't this chap pretty sure to be somebody who has scraped an acquaintance with you already? I mean, if I were an international crook, even though I didn't think you were carrying that roll of film, I'm jolly certain I'd try to get into your good graces. As Uncle Warpus's favourite nephew, you'd be a valuable person to make friends with… Doesn't that sound reasonable?"
By this time they were all eagerly engrossed, in the business, floundering as they tried to stand or sit in the creaking cabin, and each playing with theories. Warren, who had produced paper cups and was pouring out drinks, stopped. He handed a cup carefully to Peggy Glenn before he spoke. Then he said:
"It's a funny thing you should say that…
"Well?"
"Aside from yourselves, I know very few people aboard this tub. The weather's been too bad, for one thing. But it's funny." He blew into a folding paper cup savagely to open it; then he looked up. "There were — let's see — there were five people in the wireless-room at the time my cable came through, aside from the operator and myself. There was
Captain Whistler, who was having some kind of whispered row with the operator; he walked out in a turkey-cock rage. There was a girl I hadn't seen before. Wash out the captain and that girl, and there were three men. One of 'em I didn't know; didn't notice him at all… But the last two are the only other people I do know. One was that fellow Woodcock, the travelling salesman for the bug-powder firm; and the other was Dr. Kyle, who sits at our table."
