The man at the desk turned to Purdie, glancing at Lauriston.
"About those rings?" he asked. "What's Mr. Lauriston got to say?"
"Let me tell," said Purdie, as Lauriston was about to speak. "Mr. Lauriston," he went on, "has been to Peebles, where his father and mother lived. He has seen an old friend of theirs, Mrs. Taggart, who remembers the rings perfectly. Moreover, she knows that they were given to the late Mrs. Lauriston by a Mr. Edward Killick, a London solicitor, who, of course, will be able to identify them. As to the marks, I think you'll find a trade explanation of that—those rings and the rings in Multenius's tray probably came from the same maker. Now, I find, on looking through the directory, that this Mr. Edward Killick has retired from practice, but I've also found out where he now lives, and I propose to bring him here. In the meantime—I want to know what you're going to do about Mr. Lauriston? Here he is!"
The superior official glanced at the New Scotland Yard man.
"I suppose your people have taken this job entirely in hand, now?" he asked.
"Entirely!" answered the detective.
"Got any instructions about Mr. Lauriston?" asked the official. "You haven't? Mr. Lauriston's free to go where he likes, then, as far as we're concerned, here," he added, turning to Purdie. "But—he'd far better stay at hand till all this is cleared up."
"That's our intention," said Purdie. "Whenever you want Mr. Lauriston, come to me at my hotel—he's my guest there, and I'll produce him. Now we're going to find Mr. Killick."
He and Lauriston and Guyler walked out together; on the steps of the police-station Ayscough called him back.
"I say!" he said, confidentially. "Leave that Mr. Killick business alone for an hour or two. I can tell you of something much more interesting than that, and possibly of more importance. Go round to the Coroner's Court—Mr. Lauriston knows where it is."
