“That’s what I’ve felt. And, what’s more, I’ve felt that his skeleton may be lying there now.”

“You suggest some agreeable reflections. Do you mean to say that, during all these years, no one has been in the house to see?”

“No one.” He paused; presently adding, in a tone which he intended should be pregnant with meaning, “At least, until shortly before this last Christmas. And I’ve no certainty about that. A man can only draw his own conclusions.”

“What do you mean?”

“You see those shutters? Well, for over twenty years there weren’t any shutters hiding those windows. One morning I looked across the street, and there they were.”

“Someone had put them up in the night?”

“That was my impression. But Mrs. Varley, who lives next door to this, says that she noticed them coming for about a week. Each morning there was another window shuttered. She never mentioned a word of it to me; so that I can only tell you that when I saw them first they were all up.”

“Who was responsible for their appearance?”

“That’s what I should like to know. Directly I clapped eyes on them I went straight across the road, and knocked at the door; thinking that if old Robertson had come back—though he’d be pretty ancient if he had—I might get my money after all; and that if he hadn’t there’d be no harm done. But no more attention was paid to me than if I hadn’t been there. I daresay that if I’ve knocked once since I’ve knocked twenty times; but, though I’ve always felt as if there was someone inside listening, I’ve never seen a soul about the place, and no one has ever answered. I tell you what; there’s something queer about that house. More than once it’s been on the tip of my tongue to warn a policeman to keep an eye on it. It’s my opinion that London will hear about it yet.”

Mr. Kennard was oracular. When, however, on quitting his establishment I glanced at No. 84, I myself was conscious of a queer feeling that there was an unusual atmosphere about the house, as if something strange was brooding over it. I told myself that I was still a little bilious, and imagined things.
