Swindle - Burton Shirley

Swindle: Mystery at Sea is another book in the Inspector Furnace Mysteries series.  

In this light-hearted, old-fashioned British whodunit, Inspector Furnace and his new wife Martha depart from their Inn in England's countryside for a transatlantic sailing on the luxurious Queen Elizabeth ship to New York City. A delightful array of characters become suspects of a crime on the ship and they participate as a dinner club on the ship in finding the culprits with the help of Inspector Furnace.
