Kate owns and runs a gambling nightclub, and one night she surprises a thief in her office, and is shot and killed. A young girl who works for Kate named Jamie, witnesses the murder and flees the scene. Jamie had orders from Kate to contact Harry in the case of her death, taking to him a note revealing that she kept a notebook with the names of important people, which she used for her own protection. This leads Harry down a trail of investigation that involves the blackmail of several important people whose names are in the little black book, resulting in the murder of several individuals and an attempt on Orwell's life.
