From beloved British novelist David Ambrose comes a spy thriller unlike any other about why some memories are better off buried.
Charlie Monk is the ultimate spy. He has no conscience, no fear -- and no memory. Dr. Susan Flemyng thinks she may have found a way to give him his memory back. As the two of them embark on a series of experiments to recover Charlie's long-lost memory, they find something terrifying in the deepest recesses of his mind.
