Ascanio, however, was not sent for trial. No less a personage than the Italian Ambassador himself came forward and testified at the police-court proceedings that Ascanio had been with him at the Embassy from eight till nine that evening. The prisoner was discharged. Naturally, a lot of people thought that the crime was a political one, and was being deliberately hushed up.

Poirot had taken a keen interest in all these points. Nevertheless, I was somewhat surprised when he suddenly informed me one morning that he was expecting a visitor at eleven o’clock, and that that visitor was none other than Ascanio himself.

“He wishes to consult you?”

“ Du tout , Hastings. I wish to consult him.”

“What about?”

“The Regent’s Court murder.”
