“Of course I had, right along,” I defended my skill as a sleuth. That was while he was still in the hospital. “I didn’t believe Sherry was cracked. He was one hard, sane-looking scoundrel. And I didn’t believe he was the sort of man who’d be worried much over any disgrace that came his way. I was willing enough to believe that he was out for Kavalov’s scalp, but only if there was some profit in it. That’s why I went to sleep and let the old man’s throat get cut. I figured Sherry was scaring him up—nothing more—to get him in shape for a big-money shakedown. Well, when I found out I had been wrong there I began to look around.
“So far as I knew, your wife was Kavalov’s heir. From what I had seen, I imagined your wife was enough in love with you to be completely in your hands. All right, you, as the husband of his heir, seemed the one to profit most directly by Kavalov’s death. You were the one who’d have control of his fortune when he died. Sherry could only profit by the murder if he was working with you.”
“But didn’t his breaking my arm puzzle you?”
“Sure. I could understand a phony injury, but that seemed carrying it a little too far. But you made a mistake there that helped me. You were too careful to imitate a left-hand cut on Kavalov’s throat; did it by standing by his head, facing his body when you cut him, instead of by his body, facing his head, and the curve of the slash gave you away. Throwing the knife out the window wasn’t so good, either. How’d he happen to break your arm? An accident?”
“You can call it that. We had that supposed fight arranged to fit in with the rest of the play, and I thought it would be fun to really sock him. So I did. And he was tougher than I thought, tough enough to even up by snapping my arm. I suppose that’s why he killed Mickey too. That wasn’t on the schedule. On the level, did you suspect us of being in cahoots?”
I nodded.
