Philadelphia, 1921. Edie Shippen has officially started her new career as a private investigator... even though she has yet to book a client. When she runs into an old friend, the film actress Ava Sylvester, Edie is delighted at the chance to rekindle their relationship. But when Ava's co-star and new husband, Duncan, dies suddenly, all signs point to Ava. Edie's first official case begins in earnest, desperately trying to clear her friend's name. Gilbert Lawless has carved out a peaceful existence as a coroner's assistant. The last thing he wants is to jeopardise his position by involving himself with Edie Shippen. But when the body count racks up, Gilbert finds himself drawn into Edie's investigation on the set of Philadelphia's most famous film studio, where everyone seems to have something to hide. As the cameras roll, Edie and Gilbert race to catch a poisoner before one of them ends up being the next body in the morgue.
