Jake Evans is a former police detective who retired after a criminal discovered where he lived and killed his wife. He eventullay became a private-eye working for the highest bidder, but soon discovered that he had the ability to see ghosts. A specter in the form of his deceased wife serves as his companion, helping him to contact the spirits and to see things he normally would not. He also serves as a mentor and adviser to a group of young people with special powers and abilities, often homeless or growing up in poor areas calling themselves the Underground.
