A London gangster brings terror and murder to Bath, but is he about to meet his match in Patrick Gillard and Ingrid Langley?

Damien ‘Spike’ Baker is a young voyeur who loves to climb up trees, houses, walls . . . and look in people’s windows. But when he climbs up some rampant ivy on a large house and peers through one of its windows, he makes a deadly mistake. What did he see?

Detective Chief Inspector James Carrick of Bath CID is dealing with a raid on a jeweller’s shop. Then he breaks his leg and has the discovery of Damien’s body on a building site near the River Avon to contend with. Fortunately his old friend, Patrick Gillard, now retired – almost – from the National Crime Agency, offers to assist with the investigation. Can Patrick and his wife and working partner, Ingrid Langley, catch an out-of-control psychopath intent on strangling everyone who gets in his way?
