“But the envelopes are not here. Have you kept any of them?”

“I hardly know; there may be some at home. Is it important?”

“It may be; but those I can see at another time. Please go on.”

“These things continued to arrive, as I have said, and I continued to burn them till I began to find myself watched and followed, and then I kept them. That was two or three months ago. It is a most unpleasant sensation, that of feeling that some unknown person is dogging your footsteps from corner to corner and observing all your movements for a purpose you are doubtful of. Once or twice I turned suddenly back, but I never could catch the creatures, of whom I am sure Penner was one.”

“You saw these people, of course?”

“Well, yes, in a way—with the corner of my eye, you know. But it was mostly in the evening. It was a woman once, but several times I feel certain it was Penner. And once I saw a man come into my garden at the back in the night, and I feel quite sure that was Penner.”

“Was that after you had this request to put the article demanded on the stone seat in the garden?”

“The same night. I sat up and watched from the bath-room window, expecting someone would come. It was a dark night, and the trees made it darker, but I could plainly see someone come quietly over the wall and go up to the seat.”

“Could you distinguish his face?”

“No; it was too dark. But I feel sure it was Penner.”
