The Problem Professor: Doro Banyon Cozy Historical Mysteries (Doro Banyon Historical Mysteries Book 4) (Kindle Edition)

After spending the summer with her parents in Colorado, Doro, college librarian and amateur sleuth, plans to enjoy a luxurious respite in posh surroundings on the train trip home. Traveling with her best friend and her grandmother adds to her enthusiasm until an accident occurs, and part of the train must be left behind. Hours later, a passenger who has crossed swords with several others on board is found dead. As the news spreads, apprehension stalks those stranded with the unknown killer. With no way to contact help and no towns nearby, a sense of foreboding permeates the atmosphere. Passengers and crew grow increasingly apprehensive.

Who murdered the victim and why? Suspects abound. In the midst of chaos and fear, Doro remembers past cases and resolves to crack this one, too, but the perpetrator is watching her every move. Can she catch him before he nabs her?
