 "We've assumed that the blackmailer of Mrs. Ferrars is necessarily the murderer of Mr. Ackroyd. Mightn't we be mistaken?"

Poirot nodded energetically.

"Very good. Very good indeed. I wondered if that idea would come to you. Of course it is possible. But we must remember one point. The letter disappeared. Still, that, as you say, may not necessarily mean that the murderer took it. When you first found the body, Parker may have abstracted the letter unnoticed by you."

"Parker?"

"Yes, Parker. I always come back to Parker—not as the murderer—no, he did not commit the murder; but who is more suitable than he as the mysterious scoundrel who terrorized Mrs. Ferrars? He may have got his information about Mr. Ferrars's death from one of the King's Paddock servants. At any rate, he is more likely to have come upon it than a casual guest such as Blunt, for instance."

"Parker might have taken the letter," I admitted. "It wasn't till later that I noticed it was gone."

"How much later? After Blunt and Raymond were in the room, or before?"

"I can't remember," I said slowly. "I think it was before—no, afterwards. Yes, I'm almost sure it was afterwards."

"That widens the field to three," said Poirot thoughtfully. "But Parker is the most likely. It is in my mind to try a little experiment with Parker. How say you, my friend, will you accompany me to Fernly?"
