Real estate mogul Derek J. Turpin, a chocolate company, and a journalist present the Dickens Detective Agency with its greatest challenge yet. After returning from a honeymoon cruise aboard a sailing ship, Damien and Millie land a plum assignment - a trip to Montreal to run a simple background check on a chocolate company. But, their plans are disrupted when a fellow passenger from their cruise comes to them for protection. What did Barbara Lafleur, a travel writer for a Montreal newspaper, learn about Derek Turpin's activities that has put her in fear for her life? After she is struck by a car in a deliberate hit-and-run, it's up to Team Dickens to put a stop to Turpin's schemes.
