Her job is to bring that soul back at any cost, and as punishment for straying she takes ownership of them. Most endure eternal torture, some are slaves, and then there are the few who somehow escape. Learning that this soul was taken by force however, Naomi decides to end Latimer's life. In need of help, Latimer goes to an old friend (literally), Rafiq Haroun, a spirit who never left his grave. From here all the advice he is given is to find part of Naomi's blood line here in the city.
Not long after Nanette runs away from Latimer, angry after a fight they had just had. She stumbles into an apartment deep in Chicago. Knowing no human can see here, she decides to stay here for awhile. When the owner comes home however, he is able to see her. At first Nanette thinks he was sent by Naomi, but learns it is her brother Cedric. He had been in exile for some time now, but is still able to see the supernatural such as ghosts, demons, and more. Having knowledge of how to defeat his sister and keep both Latimer and Nanette alive, or in Nanette's case safe, he agrees to help them.
Along the way, Latimer's neighbor Godfried and his dog Fluffy constantly spy on him. Though they can't see Nanette, they can definitely see Cedric and Naomi when she stops by to give the two misfits a warning. Godfried can come in handy, only sometimes. His constant spying and note taking reminds Latimer of important details in his life that he can use to stop Naomi, such as a special amulet.
With one goal in mind, Latimer and Nanette have to destroy Naomi somehow to prevent an eternal life of suffering.
