When Chief Inspector Lorimer returns from his holiday on the island of Mull, he feels a welcome sense of calm. But it doesn’t last long. Kelvin FC’s new star midfielder is found brutally stabbed to death in his own home and, with his wife apprehended trying to leave the country, a seemingly straightforward new case begins. But the grisly murder of a referee after a Kelvin match throws light on some dark secrets at the ground. And when the latest signing to the club becomes the latest victim in a string of killings, Lorimer knows there’s a serial killer on the loose – one that’s only beginning to show his true colours. As lies emerge and tensions build, the players and managers live under the constant threat of becoming the next Kelvin fatality.
