'Mesmerising, compulsive, deliciously dark - and so good on the complex and thorny bond between friends. Kate Hamer's writing is incandescent.' Lucy Foley, author of The Hunting Party

Phoebe stands on Pulteney Bridge, tights gashed from toe to thigh. The shock of mangled metal and blood-stained walls flashes through her mind as she tries to cover her face so she won't be recognised. It wouldn't do to be spotted looking like this. She's missing a shoe. She feels sick.

Phoebe thought murder and murder happened. Thoughts are just thoughts, they said. Now she knows they were wrong.

At home, Phoebe arranges the scissors and knives so they point toward her mother's room. She is exhausted, making sure there's no trace of herself - not a single hair, not even her scent - left anywhere in the house. She must not let her thoughts unravel, because if they do, there's no telling who might be caught in the crossfire, and Phoebe will have to live with the consequences.
