When the body of Penny Wake, a young red-haired housewife, is found in undergrowth by a couple out jogging, DI Friend and the Murder Investigation Team are called in to investigate her death. There are no signs of a struggle but her body has been cleaned inside and out with bleach - the police know they are looking for a calculating and forensically aware killer.

Her husband, Henry, has no alibi for the night of her murder and is consequently their prime suspect, but when another red-haired woman is brought into the local hospital drugged and disorientated a new line of enquiry opens up for the police team which will lead them to one man's terrible and dark secret.
