The claimant smiled, and nodded genially to the young man whose uncle he alleged himself to be.
"I wish to remain Mr. Cave," he said. "I don't want to turn my nephew out of title and property, so long as he will do something for his old uncle. Call me Mr. Cave, by all means."
"We must talk—and at once," said Mr. Carless. "There are several points arising out of your evidence on which you must give me information. Whoever is at the back of that woman who handed you those papers is probably the murderer of John Ashton—and that is what must be got at. Now, where can we have a conference—immediately?—Your office, Methley, is not far away, I think."
"My house is nearer," said Viner. "Come—we shall be perfectly quiet in my study, and there will be nothing to interrupt us. Let us go now."
A police official let them out by a side-door, and Viner and Mr. Pawle led the way through some side-streets to Markendale Square, the others coming behind, conversing eagerly about the events of the morning. Mr. Pawle, on his part, was full of excitement.
"If we can only trace that woman, Viner!" he exclaimed. "That's the next thing! Get hold of her, whoever she is, and then—ah, we shall be in sight of the finishing-part."
"What about tracing the whole lot through the check he has given?" suggested Viner. "Wouldn't that be a good way?"
"We should have to wait nearly a month," answered Mr. Pawle. "And even then it would be difficult—simple though it seems at first sight. There are folk who deal in post-dated checks, remember! This may have been dealt with already—aye, and that diamond too; and the man who has got the proceeds may already be many a mile away. Deep, cunning folk they are who have been in this, Viner. And now—speed is the thing!"
Viner led his guests into his library, and as he placed chairs for them round a centre table, an idea struck him.
"I have a suggestion to make," he said with a shy smile at the legal men. "My aunt, Miss Penkridge, who lives with me, is an unusually sharp, shrewd woman. She has taken vast interest in this affair, and I have kept her posted up in all its details. She was in court just now and heard Mr. Cave's story. If no one has any objection, I should like her to be present at our deliberations—as a mysterious woman has entered into the case, Miss Penkridge may be able to suggest something."
