“Yours faithfully
“P. T. RENAULD.”

Below the signature was a hastily scrawled line, almost illegible: “For God’s sake, come!”

I handed the letter back with quickened pulses.

“At last!” I said. “Here is something distinctly out of the ordinary.”

“Yes, indeed,” said Poirot meditatively.

“You will go of course,” I continued.

Poirot nodded. He was thinking deeply. Finally he seemed to make up his mind, and glanced up at the clock. His face was very grave.

“See you, my friend, there is no time to lose. The Continental express leaves Victoria at 11 o’clock. Do not agitate yourself. There is plenty of time. We can allow ten minutes for discussion. You accompany me, n’est-ce pas?

“Well—”

“You told me yourself that your employer needed you not for the next few weeks.”
