His blurred senses were conscious of the strange medley produced by the familiar noises of a railway station blending with the quietly authoritative voice of the chief inspector.

"Mr. Furneaux and I have the inquiry in hand, Mr. Theydon," the detective was saying. "We called at your flat, and Bates told us of the sounds you both heard about 11:30 last night. I'm afraid we have rather upset you by coming here, but Bates was unable to say what time you would return home, so I thought you would not mind if we accompanied him in order to find out the hour at which it would be convenient for you to meet us at your flat—this evening, of course."

"You have certainly given me the shock of my life," Theydon gasped. "That poor woman dead, murdered! It's too awful! How was she killed?"

"She was strangled."

"O, this is dreadful! Shall I wire an apology to the man I'm dining with?"

"No need for that, Mr. Theydon," said Winter, sympathetically. "I'm sorry now we blurted out our unpleasant news. But you had to be told, and it was essential that we should get your story some time tonight. Can you be home by eleven?"

"Yes, yes. I'll be there without fail."

"Thank you. We have a good many inquiries to make in the meantime. Goodby, for the present."

The two made off. Winter had done all the talking, but Theydon was far too disturbed to pay heed to the trivial fact that Furneaux, after one swift glance, seemed to regard him as a negligible quantity. It was borne in on him that the detective evidently believed he had something of importance to say, and meant to render it almost impossible that he should escape questioning while his memory was still active with reference to events of the previous night.

And he had so little, yet so much, to tell. On his testimony alone it would be a comparatively easy matter to establish beyond doubt the identity of Mrs. Lester's last known visitor. And what would be the outcome? He dared hardly trust his own too lively imagination. Whether or not his testimony gave a clew to the police, the one irrevocable issue was that somewhere in London there was a girl named Evelyn who would regard a certain young man, Francis Berrold Theydon to wit, as a loathsome and despicable Paul Pry.
