"No, for I met her a few months ago only, at Antibes." "And Mr. Carter, too?"

"Ah no, Mr. Carter did not accompany his wife! I met Mr. Carter for the first time on Friday, when I arrived to spend the week-end here. Little did I think then it would end in such tragedy!"

"No, sir. I understand that you were one of the last people to see Mr. Carter before he set out for the Dower House this afternoon?"

"Is it so indeed? That I did not know, for I myself was gone from the house before he left it. I asked of him the way to Dr Chester's house. Miss Cliffe, I think, was present. Yes, I am sure. I left her with him."

"At what time would that have been, sir?"

The Prince shook his head. "I am sorry. I cannot tell you. It was certainly more than half past four, but I cannot be precise, for I had not the occasion to look at my watch."

"What did you do when you left the house, sir?"

"But naturally I walked to the garage. I should explain, perhaps, that Miss Fanshawe was so very kind as to lend me her car. I drove myself, therefore, to the doctor's house."

"Did you happen to notice what the time was when you arrived there?"

The smile flashed out again. "It is, I see, very fortunate for me that I can say yes, Inspector. Mr. Carter told me it was impossible that I should mistake the house, and this I found was entirely true. I did, in fact, arrive at five minutes to five. The doctor was not in: he had been called out, his housekeeper told me. But in perhaps ten minutes he came back, and we had tea together, and he showed me his relics, until it was time for him to go to his surgery. Then I motored back here, to find - what horror!"
