Alison Hart is a medium by trade. She and her cynical assistant the slender flint-hearted Colette travel the clubs and psychic fairs of London's orbital road - Alison passing on the messages of the dead. But behind Alison’s plump smiling public persona is a tormented woman - being a bridge between the living and the dead can be an affliction not a blessing. Her days and nights are haunted by the unpleasant thugs and petty criminals that she grew up with; men who visited her prostitute mother harrassing and preying upon Alison. The more she tries to be rid of their ghosts the stronger and nastier they become.
