"Surprises around every corner. Mass Transit is an enjoyable ride in NYC from the 1900s." -Dale B. Ward, author of Killing the Butterfly

Birdie Kelley, a former stage actress, has hit bottom and struggles to overcome severe injuries and find love. A prominent Broadway producer calls. Instead of a stage roll, he offers her a case. His daughter had been savagely killed. She and her new PI license hit the streets of Manhattan running, breaking laws and making enemies. Revenge motivates her to show up a former lover and NYC detective.

She discovers the killing was a result of a mistaken identity. The axe killer, a psychotic NYC Transit cop experimenting in spiritual meditation, mistook the victim for his ex-girlfriend. Complications occur which prevent her from arresting the transit cop. A crooked homicide detective has a conflicting interest. He's recruited the transit cop for another case involving a newly formed Russian mob. Conflict escalates after Birdie plants evidence on her suspect and in turn, the unstable transit cop sets a trap for her.

The final curtain drops with the transit cop receiving a visit by an archangel of death.
