The Return of Sherlock Holmes
"See here, mister," said he. "I make no complaint of being man-handled in this fashion, but I would have you call things by their right names. You say I murdered Peter Carey, I say I killed Peter Carey, and there's all the difference." (Black Peter.112)
"I've had to do with fifty murderers in my career, but the worst of them never gave me the repulsion which I have for this fellow. [...]"
"He is the king of all blackmailers." (Milverton.1.7-9)
"You know, Watson, I don't mind confessing to you that I have always had an idea that I would have made a highly efficient criminal. This is the chance of my lifetime in that direction." (Milverton.1.78)
