Giraud shook his head.

“The man is a Frenchman—I would take my oath of that—”

But at that moment they were interrupted by the doctor who was sitting back on his heels with a perplexed expression.

“You say he was killed yesterday morning?”

“I fix it by the theft of the dagger,” explained Giraud. “He may, of course, have been killed later in the day.”

“Later in the day? Fiddlesticks! This man has been dead at least forty-eight hours, and probably longer.”

We stared at each other in blank amazement.

The doctor’s words were so surprising that we were all momentarily taken aback. Here was a man stabbed with a dagger which we knew to have been stolen only twenty-four hours previously, and yet Dr. Durand asserted positively that he had been dead at least forty-eight hours! The whole thing was fantastic to the last extreme.

We were still recovering from the surprise of the doctor’s announcement, when a telegram was brought to me. It had been sent up from the hotel to the Villa. I tore it open. It was from Poirot, and announced his return by the train arriving at Merlinville at 12:28.
