Thousands of dog owners are becoming victims of the UK's latest crime wave: Dognapping. Their family pets are stolen from locked cars, secure gardens and even from their own houses - all for the sake of a few quid, or in the most sinister cases, for ransoms that can run into thousands of pounds. The police have other priorities, but one woman has quickly risen to become Britain's top expert in the new field of pet detection. Her name is Jane Hayes, and she'll do anything to re-unite the victims of dog theft with their pets - even as her marriage crumbles around her.
