'Let me out! Please . . .' My tiny fists pound the door, but my voice reverberates off the stone walls and hangs in the air as if suspended by spider's webs. No one comes . . .

Years later, a woman is found face-down in a pool of blood. Detective Lottie Parker is called to the remote farmhouse in the bleak Irish countryside. Inside, she finds a scene that speaks of uncontrollable rage: glasses smashed, chairs ripped apart, the woman's body broken.

A black rain jacket makes Lottie think she knows the killer's identity, but then she finds a disturbing clue: is the murder linked to an old case at St Declan's asylum - a case investigated by her own father, just before he took his life?

When another victim is left without her tongue on the hospital steps, and a young girl goes missing, Lottie knows she has to act fast. Can she face her own demons and uncover the truth before another life is taken?

An absolutely gripping page-turner from the million-copy bestselling author of Irish Top 10 bestsellers, The Missing Ones and The Stolen Girls. If you love Karin Slaughter, Tess Gerritsen and Helen Fields, you'll be completely hooked.
