Dublin, 2019: Michael Gleeson is a well-respected psychiatrist—a quiet man, a good friend, and a useless cook. He also spends part of his professional life secretly counseling former members of the disbanded IRA. Michael always thought this would be enough to satisfy his Republican heritage, but when the highly skilled yet deeply disturbed Turlough O’Sullivan enters his office, Michael sees an opportunity that he just can’t overlook.
Haunted by childhood tales of the gruesome history of the Irish people under British rule, Michael persuades his new patient to help him track down and kill the living descendants of the worst men in Ireland’s past, figures whose names still send a shiver down the spine.
But Michael’s plan for a twisted and bloody revenge doesn’t run smoothly—not only must he confront the truth about the role models who formed him as a child, but on his trail is a young detective at Scotland Yard, an officer obsessed with stopping the unknown serial killer who is out for an historical revenge that she can’t understand.
