Part thriller, part spy novel, Exchange Place is set between Belfast and Paris and tracks the individual movements of two men, John Kilfeather and John Kilpatrick, who are trying to solve a mystery concerning a lost friend, a missing notebook and a gun.

But this is no ordinary mystery and the usual rules don't apply. Appearances are deceptive; identities dissolve, become slippery; and it's easy to lose track of who you are in the winding streets and passageways of the city. As the paths of Kilpatrick and Kilfeather slowly and inexorably converge, it is only the subterranean Memory Palace that can open the way to the truth. A brilliant psychological thriller that confirms Carson as one of our most talented Irish writers.
