"We'll wait," replied Allerdyke. He dropped into a chair and drew out his cigarette-case. "Have a drink while we're waiting?" he suggested, beckoning a waiter who was passing. "What's it to be?"

"Oh—something small, then," said Fullaway. "Dry sherry. Better bring three—Van Koon won't be long."

But the minutes passed and Van Koon was still absent. Ten minutes more went, and still he did not come. And Fullaway pulled out his watch with an air of annoyance.

"Too bad of Van Koon," he said. "Time's going, and I know Delkin lunches at two o'clock. Come on, Allerdyke," he continued, rising, "we'll go over to Delkin. If Van Koon comes, he'll find us. He's probably gone off with that other man, though—he's an absent-minded chap in some things, and too much given to the affair of the moment. Come on—I'll introduce you."

The Chicago millionaire, once put in possession of Allerdyke's name, looked at him with manifest curiosity, and motioned him and Fullaway to take seats with himself and his two companions.

"We were just talking of your case, Mr. Allerdyke," he said quietly. "The Princess, of course, has told me about you. Fullaway, I don't know if you know this gentleman—his name's well enough known, anyway. This gentleman is Mr. Chilverton, the famous New York detective. Chilverton—Mr. Fullaway, Mr. Allerdyke."

Fullaway and Allerdyke both looked at the man in the Homburg hat with great interest as they shook hands with him. Fullaway at any rate knew of his world-wide reputation; Allerdyke faintly remembered that he had heard of him in connection with some great criminal affair.

"Been telling Mr. Chilverton about our business, Mr. Delkin?" asked
Fullaway pleasantly. "Asking his expert advice?"

"I've told him no more than what he could read for himself in the newspapers," answered Delkin. "He's got stuff of his own to attend to, here in London. About our affair now, as you call it, Fullaway. It's not my affair, or I guess I'd have been more into it by this time. The Princess here thinks things are going real slow, and so do I. What do you think, Mr. Allerdyke!"

"It's a case in which things go slow of sheer necessity," replied Allerdyke. "It's a case of widespread ramifications—to use a long word. But—we keep having developments, Mr. Delkin. There's been one this morning. We came to see you about it—and perhaps you'll let Fullaway tell!—he'll put things into fewer words than I should."
