Aisling always felt like a piece of herself is missing. Desperate to find answers, she uploads her DNA to an ancestry website. But instead of finding answers, she comes face to face with Detective Jonah Sheens. Her DNA is a match for recent serial killer crime scenes. The police have three lead suspects: her father, or one of her two sons.

Gytha Lodge lives in Cambridge with her son. She Lies in Wait, her debut novel, was a Sunday Times bestseller, a Richard & Judy Book Club pick and an international bestseller. Set in the New Forest and the surrounding area, Lodge's highly-acclaimed DCI Jonah Sheens series also includes Watching From the Dark, Lie Beside Me and Little Sister. A Killer in the Family is the fifth instalment in the series.
