"I remained at the head of the stairs. For quite a while I remained at the head of the stairs. Then I crope ..."

"You what?"

"I crope to the door of the picture gallery."

"Oh, I see. Yes?"

"Because the sneezing seemed to have come from there. And then I heard another sneeze. Two or three sneezes, Mr. John. As if whoever was in there had got a nasty cold in the head. And then I heard footsteps coming toward the door."

"What did you do?"

"I went back to the head of the stairs again, sir. If anybody had told me half an hour before that I could have moved so quick I wouldn't have believed him. And then out of the door came a man carrying a bag. He had one of those electric torches. He went down the stairs, but it was only when he was at the bottom that I caught even a glimpse of his face."

"But you did then?"

"Yes, Mr. John, for just a moment. And I was stottled."

"Why? You mean he was somebody you knew?"
