“Not since,” replied Mrs. Walters. “No—and I was wondering if he’d be coming round, because——” She paused there and looked at Spargo with particular enquiry—“You’re a friend of his, aren’t you?” she asked. “I suppose you know as much as he does—about this?”

“He and I,” replied Spargo, with easy confidence, “are working this case together. You can tell me anything you’d tell him.”

The landlady rummaged in her pocket and produced an old purse, from an inner compartment of which she brought out a small object wrapped in tissue paper.

“Well,” she said, unwrapping the paper, “we found this in Number 20 this morning—it was lying under the dressing-table. The girl that found it brought it to me, and I thought it was a bit of glass, but Walters, he says as how he shouldn’t be surprised if it’s a diamond. And since we found it, the waiter who took the whisky up to 20, after Mr. Marbury came in with the other gentleman, has told me that when he went into the room the two gentlemen were looking at a paper full of things like this. So there?”

Spargo fingered the shining bit of stone.

“That’s a diamond—right enough,” he said. “Put it away, Mrs. Walters—I shall see Rathbury presently, and I’ll tell him about it. Now, that other gentleman! You told us you saw him. Could you recognize him—I mean, a photograph of him? Is this the man?”

Spargo knew from the expression of Mrs. Walters’ face that she had no more doubt than Webster had.

“Oh, yes!” she said. “That’s the gentleman who came in with Mr. Marbury—I should have known him in a thousand. Anybody would recognize him from that—perhaps you’d let our hall-porter and the waiter I mentioned just now look at it?”

“I’ll see them separately and see if they’ve ever seen a man who resembles this,” replied Spargo.

The two men recognized the photograph at once, without any prompting, and Spargo, after a word or two with the landlady, rode off to the Atlantic and Pacific Club, and found Ronald Breton awaiting him on the steps. He made no reference to his recent doings, and together they went into the house and asked for Mr. Aylmore.
