The Expats

A unique and twisty debut spy thriller from former book editor Chris Pavone, in which the main character is an ex-CIA agent who has given up her job to move to Luxembourg for her husband's banking career. When another American couple befriends them, her spy-instincts start to tingle. Are they being watched? And is it her they are after, or her husband. Good stuff, structured in such a way that it's constantly surprising.
