That said, the novel is wonderful, and a masterful example of building suspense through realistic characters and subtlety. Much of the suspicion towards the main character, Andy Bentley, comes from his own wife, Claire, through a combination of their collective insecurities, little white lies he tells, and her misunderstanding of overhearing only part of a phone conversation he has.

   Two people on two different continents are brutally murdered and Andy receives disturbing emails that hint he may have a personal connection to the victims. At the same time, he meets a mysterious client who leads him down a chain of intrigue.

   I don’t want to reveal any more of the plot because Campbell skillfully draws us in by hurling us into the points of view of Andy and Claire, unraveling the mystery only small amounts at a time since you only know what they know.

   A fine psychological thriller indeed.
