“Nevertheless, it is necessary,” said Poirot calmly. “It is necessary for this reason⁠—Grant is not the murderer.”

“What? Who, is, then?”

“The murderer was, I should fancy, a youngish man. He drove up to Granite Bungalow in a trap, which he left outside. He went in, committed the murder, came out, and drove away again. He was bareheaded, and his clothing was slightly bloodstained.”

“But⁠—but the whole village would have seen him!”

“Not under certain circumstances.”

“Not if it was dark, perhaps; but the crime was committed in broad daylight.”

Poirot merely smiled.

“And the horse and trap, sir⁠—how could you tell that? Any amount of wheeled vehicles have passed along outside. There’s no mark of one in particular to be seen.”
