Code to Zero, by Ken Follett

A man wakes up in Washington D.C. in a public toilet with no memory. He is dressed like a bum and smells like he's been on a bender. He doesn't know his name but discovers he is remarkably skillful at spy craft and staying alive while being chased. If this sounds a lot like The Bourne Identity then you are right—except for without the compelling characters and exciting plot. One dimensional and trite, this is a huge disappointment from a talented writer like Follett. Don't read this—go pick up his Pillars of the Earth instead.

First Sentence:

He woke up scared.
