Memory

The main character is an actor (Paul Edwin Cole) in a traveling company. While out of town where nobody knows him, he sustains a head injury, causing severe memory loss. He's left to fend for himself when the acting company moves on. The story is about how he gradually finds or re-creates himself and his life.

Not a typical Westlake; closer to the ones he wrote under other names. Very haunting. Amazing how Mr. Westlake gets into the character's head. Story has it that this was Mr. Westlake's first book, but it wasn't published until after he died.
