“Of course he killed her. Who else could have done so?”
“I don’t know. But I’m sure he didn’t kill her.”
“He went into that house three minutes after her and came out as white as a sheet.”
“Because he found her dead.”
“But nobody else went in.”
“Then the murderer was in the house already, or else he got in some other way. There’s no need for him to pass the lodge, he could have climbed over the wall.”
Suzanne glanced at me sharply.
“‘The Man in the Brown Suit,’” she mused. “Who was he, I wonder? Anyway, he was identical with the ‘doctor’ in the Tube. He would have had time to remove his make-up and follow the woman to Marlow. She and Carton were to have met there, they both had an order to view the same house, and if they took such elaborate precautions to make their meeting appear accidental they must have suspected they were being followed. All the same, Carton did not know that his shadower was the ‘Man in the Brown Suit.’ When he recognized him, the shock was so great that he lost his head completely and stepped back onto the line. That all seems pretty clear, don’t you think so, Anne?”
I did not reply.
“Yes, that’s how it was. He took the paper from the dead man, and in his hurry to get away he dropped it. Then he followed the woman to Marlow. What did he do when he left there, when he had killed her—or, according to you, found her dead. Where did he go?”
