Lost Soul: Harbinger P.I.

Alec Harbinger is a preternatural investigator, a hunter of things that go bump in the night. When his employers, the Society of Shadows, banish him from his Chicago office to a small town in Maine, Alec thinks his career and life are over. How is a preternatural investigator supposed to find work in a sleepy town in the middle of nowhere? But when a local teenager comes back from a weekend at the lake with an altered personality, Alec is hired to investigate a possible demon possession. A young man turning up at Alec's office insisting he's been bitten by a werewolf adds to the caseload. And just to make his first day at the office perfect, Alec discovers that someone in the Society of Shadows is trying to kill him with ogre assassins. No work for a preternatural investigator in a sleepy Maine town? Yeah, about that...
