What I try to do is write a story about a detective rather than a detective story.

The puzzle isn't so interesting to me as the behavior of the detective attacking it.

Dashiell HammettI distrust a man that says when. If he's got to be careful not to drink to much it's because he's not to be trusted when he does.
