“6:40 to Montreal: A Novel” by Eva Jurczyk starts with a good premise. A successful mystery writer takes a first-class train trip from Toronto to Montreal on the week between Christmas and New Year’s Day. Caught in a terrible blizzard, the train suddenly grinds to a halt halfway to the destination. The doors between cars are locked, and the mystery writer is trapped with a small group of strangers.
Suddenly, one of the passengers slumps over dead. Since everyone’s been locked in the train car, one of them must be a killer. Who might be next?
