1968, Sicily. Just months after a terrible earthquake has destroyed the mountain town of Gibellina, Enzo and his wife Irene Borgata are making their way back to the family home, Villa Alba, on roads overlooked by the eerie backdrop of the flattened ghost town. When their car breaks down, Enzo leaves his young wife to go and get help, but when he returns there is no trace of Irene. No body, no sign of a struggle, nothing.

2003. TV showman and true crime aficionado Milo Conti is Italy's darling, uncovering and solving historic crimes for his legion of fans. When he turns his attention to the story of the missing Irene Borgata, accusing her husband of her murder, Enzo's daughter Maddi asks her childhood friend, retired detective April Cobain, for help to prove her father's innocence. But the tale April discovers is murky: mafia meetings, infidelity, mistaken identity, grief and unshakable love. As the world slowly closes in on the claustrophobic Villa Alba, and the house begins to reveal its secrets, will the Borgata family wish they'd never asked April to investigate? And what did happen to Enzo's missing wife Irene?

Bestselling author Louise Douglas returns with an irresistibly compelling, intriguing and captivating tale of betrayal, love, jealousy and the secrets buried in every family history.
