The bodies of vulnerable young women keep piling up. And every one of them reminds him of his own failure... Detective Chief Inspector Ronald Carlson thought he'd seen the worst of it. But nothing could have prepared him to discover his own daughter hanging by a knot she tied herself. So when his first case after a leave of absence is a strangled prostitute of the same age, he vows to redeem himself by bringing her murderer to justice. Repulsed by the grisly scene, Carlson follows the trail of clues... to another dead sex worker and a mocking video from the depraved madman responsible. As the body count rises, the beleaguered detective races the clock to catch the killer before more parents lose their daughters. Can Carlson get inside the mind of a monster before more women end up in the morgue? Tangent is the first book in the gritty DCI Ronald Carlson police procedural series. If you like strong characters, twisted villains, and graphic crime, then you'll love Caroline Goldsworthy's atmospheric thriller.
