From the author of This Books Kills comes another twisty mystery that's part Agatha Christie, part Karen McManus. Trapped in a mansion with a murderer and a family of liars - how would you survive?

When Devi, Lizzie, and Jayne get snowed in and stranded at the grand Bramble Estate, home of the wealthy Vanforte family, they find themselves accidentally right in the middle of a murder plot. The matriarch, Emily Vanforte, has been poisoned at her own dinner party, and whoever did it is still on the loose.

The killer could only be one of four people: Charles, Emily's notorious politician husband; Lottie their seemingly perfect teenage daughter; Douglas, Lottie's good-for-nothing boyfriend; and Tate, Charle's nephew who is more than meets the eye.

Cut off from help, confined in an isolated house with a killer, and surrounded by suspects, the girls decide to solve the mystery before one of them becomes the next victim. But no one is safe with knives hidden under the floorboards, vanishing guns, and secret passages in the walls. And in a house full of liars, how will they ever discover the truth in time?
