You were on the train, returning to the big city after seeing your folks in your hometown. You were reading a newspaper about recent homicides in town that the police had not yet apprehended.

A young man strolled in and sat by you as the cabin door slid open. Before saying out, he spotted the document you were holding.

"I wonder when he will strike again."

He said this with a knowing grin. You had no idea he was the man the cops were hunting for.
