On a hot Tuesday morning in June, Detective Chef Inspector Harry Brock is called to Richmond Park in south-west London, where the body of a young woman has been found, strangled and half-naked, in the Isabella Plantation. The killer fled the scene with nothing - except the victim's bra.

The discovery of further bodies, all women in their twenties, and all with missing bras, suggests a serial killer is at loose. With the help of Detective Superintendent Dave Poole and the rest of his team, it's not long before Harry uncovers a dark web of lies, betrayal, desire and deceit. But can he break the deadlock to catch a determined killer?
