A highly topical thriller set amongst the world of the homeless in Cambridge.

With the help of his estranged wife, and her new husband, a WPC with whom he has a brief affair; a talkative and knowledgeable 'Big Issue' seller and a collection of rough sleepers and market traders Frank gets nearer to the truth. But this only increases the danger to him and those helping him. An explosive culmination to his quest will bring violence and further death to the city.
