Max Darke, only two years out of Hendon Police Training, finds himself heading up the Demon Division at Scotland Yard. When a nest of Level 3 demons decide to make London their favourite party town, his only help is a Level 2 demon called Sophie, who isn't entirely trustworthy since Max killed her and had her sent her Down Under (to Hell).

The Powers-That-Be have a very strange sense of humour, especially as Max and Sophie are about to battle Lilith, the Mother of All Evil.

Some days, work is Hell.
