Short review: This is a unique take on a traditional spy novel. A super spy has Alzheimer's. Everyone wants to take him out because they don't know what he might tell or do. His estranged son has no idea his father is a spy, but soon is also a target. Lots of good action, some real thoughts on the loss of capacity as Alzheimer's takes hold. If you like spy novels you will like this. If you like family drama's you will probably also like this.
