Intrigue On a Longship Cruise

Arielle and her aunt, Eloise, are going on a Longship cruise up the Rhône River in France. They are happily anticipating a week of fun meeting new people, eating gourmet food, seeing historic sites in famous cities, buying souvenirs, and photographing it all. It promises to be a lovely trip together after being cooped up at home during the recent pandemic. Vaccinated and packed, they are ready to tour the South of France, free from any worry about dangerous microbes. At least, that's what they think.
Someone else aboard their ship has other ideas, including murder, and something worse than murder. What could be worse than murder? Read the story to find out, and enjoy Arielle's photographs.
