Allerdyke rubbed his chin and knitted his brows in obvious bewilderment. "There must ha' been more than them in at it," he said musingly. "A regular gang of 'em, judging by results."

"Every gang has its ganger," replied Appleyard, with a knowing smile. "There's no doubt this is a big thing—but there must be a central point, a head, a controlling authority in it. We come back, you see, after all, to where we started—these people were the only people in England who knew about these jewels, so far as we know."

"Aye, but only so far as we know," said Allerdyke. "There may have been others. There may have been folks who got to know about them over there in Russia and who communicated their knowledge to some folks here. And there's always this to be borne in mind—the affair, the plot, may have been originated there, and worked from there. Remember that!"

"Quite so—and you can't decide on anything relating to that until this Princess comes," agreed Appleyard. "It'll have to rest till you've heard all she has to say, and then you'll know where you are. But in the meantime you can find out a bit about Fullaway and this millionaire man—I can find out for you, if you like, in a few hours."

"Do, my lad!" said Allerdyke. "It's always well to know who you're dealing with. Aye—make an inquiry or two."

"But remember that all I can inquire about will be in the ordinary business way," continued Appleyard. "I can ascertain if there is a Delkin in town, who's a Chicago millionaire, and if Fullaway's a reputable business man—but that'll be all. As to the secretary, I can't do anything."

"I'll keep an eye on her myself," said Allerdyke. "Well, do this, then, and let me know the results. I've put up at the Waldorf, and there I shall stop while all this is being investigated here in London, but I shall pop in and out here, of course. And now I'll go back there and find out if there's any fresh news from the police or from Hull. I reckon there'll be some fine reading in the newspapers in a day or two, Ambler—it'll all have to come out now."

In this supposition Allerdyke was right. The police authorities, finding that the affair had assumed dimensions of an astonishing magnitude, decided to seek the aid of the Press, and to publish the entire story in the fullest possible fashion. And Allerdyke and all London woke next morning to find the newspapers alive with a new sensation, and every other man asking his neighbour what it all meant. Three mysterious murders—two big thefts—together—the newspaper world had known nothing like it for years, and the only regrets in Fleet Street were those of the men who would have sacrificed their very noses to have got the story exclusively to themselves. But the police authorities had exercised a wise generosity, and no one newspaper knew more than another at that stage—they all, as Fullaway said to Allerdyke at breakfast, got a fair start, and from that one could run their own race.

"We shall be to these Pressmen as a pot of honey to flies," he observed. "Take my advice, Allerdyke—see none of them, and if you should—as you will—get buttonholed and held up, refuse to say a word."

"You can leave that to me," answered Allerdyke, with a twitch of his determined jaw. "It 'ud be a clever newspaper chap that would get aught out of me. I've other fish to fry than to talk to these gentry. And what good will all this newspaper stuff do?"
