"And how do these changes make you uneasy?"
"They indicate a serious situation."
"What situation?"
"I do not know; I have never stated exactly."
"Why not?"
"Because I was afraid; and I closed my eyes so that I might not see."
"See what?"
"The explanation of all that is mysterious in your life."
"When did you notice the mystery in my life?"
"At the time of Caffie's death; and before, when you told me that you could kill him without any remorse."
