"A communication from Dr. Renshaw," said Crate, with an air of great importance. "He called here this afternoon with the intention of seeing you. In your absence, he saw me; and stated that he was leaving for India to-night by the P. and O. steamer 'Oceana.' Before leaving, he wished to see and speak with you."

"Before leaving, he has to see and speak with me," retorted Fanks, coolly. "I would have him arrested on suspicion if he attempted to leave London without according me an interview."

"You have no evidence on which you can arrest him, Mr. Fanks."

"I have more evidence than you are aware of, Crate. If Dr. Renshaw could have defied me he would have done so; but he dare not. Where is he now?"

"He is still at Great Auk Street, where he has been watched ever since the night of the murder."

"When does the 'Oceana' leave the Docks?"

"To-night at ten o'clock. Dr. Renshaw goes down from Fenchurch Street by the eight train."

"It is now a quarter past five. Good! I shall call at Great Auk Street; in the meantime, I have to keep another appointment."

"Have you found out anything since I saw you last, Mr. Fanks?"

"I have found out that there is a woman in the case," said Fanks. "And that reminds me, Crate. You must go to Paris by to-night's mail. Are you busy with anything else?"
