Lark Dodge flies to Ireland to keep an eye on her convalescent father and reflect on her own marital storms, but her time-out ends before it can begin when she finds a dead man on the castle-like estate where she and her father are staying. The body is that of an unpopular American businessman with a passion for war games played out in a nearby woods. Tensions explode when another murder takes Lark into secrets of the human heart--and the gruesome atrocities the heart is capable of. Her husband’s unexpected arrival--flying to the rescue--drives Lark and Jay further apart. Then Jay vanishes, and so does the chief suspect in the two murders.
