The body of a woman with her throat ripped out is found on Saddleworth Moor, near Manchester. She is discovered in an area where numerous sightings of a mysterious big black cat have been made. When analysis shows the hairs caught under her nails are those of a panther, it's assumed the animal has killed its first human victim. But then a man DI Jon Spicer is investigating as part of an entirely different case is murdered in exactly the same way. Only this time the body is found in a secluded car park - a popular gay rendezvous far closer to the city centre. Soon DI Spicer finds himself hunting a killer dubbed The Monster of the Moor, a creature whose stealth and savagery strike terror into the local population and way beyond it.
