“I fear so, sir, though when or how I cannot say. I was ill, very ill, for a time after Paula’s—death. They were in an escritoire in my bedroom, and after I recovered I found they were gone.”

“Do you suspect anyone?”

Boris shook his head.

“Impossible to suspect the good friend with whom I live, or any of my visitors. I have wondered sometimes whether, in my delirium, I might not myself have destroyed them, on some subconscious impulse, remembering that she had told me to burn them.
