In a large house in London's fashionable Chelsea, a baby is awake in her cot.

Well-fed and cared for, she is happily waiting for someone to pick her up. In the kitchen lie three decomposing corpses. Close to them is a hastily scrawled note.

They've been dead for several days. Who has been looking after the baby? And where did they go?

Two entangled families. A house with the darkest of secrets.

A compulsive thriller from Lisa Jewell.
