Sleeping Murder (Miss Marple, #13)

by Agatha Christie

There’s a type who commits a crime, manages to get away with it, and is darned careful never to stick his neck out again.

But supposing somebody goes poking about, digging into things, turning up stones and exploring avenues and finally, perhaps, hitting the target? What’s your killer going to do about it? Just stay there smiling while the hunt comes nearer and nearer? No, if there’s no principle involved, I’d say let it alone.” He repeated his former phrase: “Let sleeping murder lie.”

Can’t you ever leave murder alone, woman? Even murder in retrospect?”

It really is very dangerous to believe people. I never have for years.”
