Against the stark beauty of southwest Ireland, veterinarian Dimpna Wilde must reckon with a stalker whose obsession has turned deadly in Carlene O’Connor’s gripping, atmospheric Irish crime novel for fans of Tana French, Dervla McTiernan, and Ann Cleeves.

Dazed and distraught, Niamh passes out after muttering incoherently, and at her apartment, Dimpna and Patrick make a grisly discovery. There’s a dead woman in Niamh’s bed, shot in the head, a hunting rifle beside her. When Niamh comes to, she has no memory of the day’s events, and no idea of the woman’s identity.
