 In an episode filmed in New York (mostly in a claustrophobic office building, although there are some exterior shots), Grady has landed work at an accounting firm where the owners are suspected of "cooking the books." Grady becomes the prime suspect when one of the partners is murdered, but Jessica discovers that a "phantom" rumored to haunt the office building is a real person, a homeless man who lives in the vents and air ducts, swipes food off desks, and may be a witness to the murder.
