“Certainly. If you know where he is——”

“I perceive that you do not believe that I do know. And yet I have told you just now that I know everything. The truth of the telephone call, of the footprints on the window-sill, of the hiding-place of Ralph Paton——”

“Where is he?” said Blunt sharply.

“Not very far away,” said Poirot, smiling.

“In Cranchester?” I asked.

Poirot turned towards me.

“Always you ask me that. The idea of Cranchester it is with you an idée fixe. No, he is not in Cranchester. He is—there!”
