Viner introduced Mr. Pawle to Miss Penkridge with the remark that she was something of an authority in mysteries, and as soon as they had sat down to lunch, told her of Langton Hyde and his statement.

"Just so!" said Miss Penkridge dryly. "That's much more likely to be the real truth than that this lad killed Ashton. There's a great deal more in this murder than is on the surface, and I dare say Mr. Pawle agrees with me."

"I dare say I do," assented Mr. Pawle. "The difficulty is—how to penetrate into the thick cloak of mystery."

"When I was round there, at Number Seven, this morning," observed Miss Penkridge, "those two talked very freely to me about Mr. Ashton. Now, there's one thing struck me at once—there must be men in London who knew him. He couldn't go out and about, as he evidently did, without meeting men.

"And there's another thing," said Miss Penkridge. "I should find out what can be told about Mr. Ashton where he came from. I believe you can get telegraphic information from Australia within a few hours. Why not go to the expense—when there's so much at stake? Depend upon it, the real secret of this murder lies back in the past—perhaps the far past."

"That too shall be done," agreed Mr. Pawle. "I shouldn't be surprised if you're right."

"In my opinion," remarked Miss Penkridge, dryly, "the robbing of this dead man was all a blind. Robbery wasn't the motive. Murder was the thing in view! And why? It may have been revenge. It may be that Ashton had to be got out of the way. And I shouldn't wonder a bit if that isn't at the bottom of it, which is at
