"He wishes to consult you?"

"Du tout, Hastings. I wish to consult him."

"What about?"

"The Regent's Court murder."

"You are going to prove that he did it?"

"A man cannot be tried twice for murder, Hastings. Endeavor to have the common sense. Ah, that is our friend's ring."

A few minutes later Signor Ascanio was ushered in - a small, thin man with a secretive and furtive glance in his eyes. He remained standing, darting suspicious glances from one to the other of us.

"Monsieur Poirot?"

My little friend tapped himself gently on the chest.

"Be seated, signor. You received my note. I am determined to get to the bottom of this mystery. In some small measure you can aid me. Let us commence. You - in company with a friend - visited the late Count Foscatini on the morning of Tuesday the 9th -"

The Italian made an angry gesture.

"I did nothing of the sort. I have sworn in court -"

"Précisément - and I have a little idea that you have sworn falsely."

"You threaten me? Bah! I have nothing to fear from you. I have been acquitted."

"Exactly; and as I am not an imbecile, it is not with the gallows I threaten you - but with publicity. Publicity! I see that you do nor like the word. I had an idea that you would not. My little ideas, you know, they are very valuable to me. Come, signor, your only chance is to be frank with me. I do not ask to know whose indiscretions brought you to England. I know this much, you came for the especial purpose of seeing Count Foscatini."

"He was not a count," growled the Italian.

"I have already noted the fact that his name does not appear in the Almanach de Gotha. Never mind, the title of count is often useful in the profession of blackmailing."

"I suppose I might as well be frank. You seem to know a good deal."

"I have employed my gray cells to some advantage. Come, Signor Ascanio, you visited the dead man on the Tuesday morning - that is so, is it not?"

"Yes, but I never went there on the following evening. There was no need. I will tell you all. Certain information concerning a man of great position in Italy had come into this scoundrel's possession. He demanded a big sum of money in return for the papers. I came over to England to arrange the matter. I called upon him by appointment that morning. One of the young secretaries of the Embassy was with me. The Count was more reasonable than I had hoped, although even then the sum of money I paid him was a huge one."

"Pardon, how was it paid?"

"In Italian notes of comparatively small denomination. I paid over the money then and there. He handed me the incriminating papers. I never saw him again."

"Why did you not say all this when you were arrested?"
