Zoe Martinique Investigation, 1. Zoe Martinique has turned her unusual ability into a career. When she's traveling, she can't be seen which makes her an ideal professional snoop.

She witnesses a murder and a soul stealing, and discovers she has unwelcome company: Trench- Coat, a ghostly killer who can see and hurt her.
