When Detective Murphy asks Dresden to help her with a series of ritualistic slayings, he discovers that werewolves are involved. Only the werewolves aren't the huggers, they're the victims. And when the FBI get's involved with the investigation, Harry becomes the prime suspect and is thrown in jail. An innocent woman is targeted by the hugger and Harry may not be able to help her.
Ever since he was a boy, Harry Dresden, knew that monsters were real, just as he was able to make things happen simply with the force of his will. As he grew he began to learn of his magical heritage, given to him by his mother, and coveted by his Uncle, who would stop at nothing to possess it.
Now that he is grown Harry is the only private investigator / wizard in Chicago and listed in the phone book. He uses real magic to help him solve his cases, much to the chagrin of both the police and the magical establishment, whose shadow wars often spill into the 'real' world and involve people who have no idea just how magical, and dark, the world can be.
