Samantha and Nellie set sail for Europe in 1906. Also aboard the ship is a world-famous archaeologist and the legendary sapphire he is carrying to a London museum. When his priceless jewel disappears, Samantha realizes that every one of the first-class passengers is a suspect--and one of them must be the thief!

Samantha and Nelly are both excited to be cruising to Europe with Grandmary and the Admiral, even though their trip will skip Ireland in pursuit of England and France. Their French tutor is wonderful, so they're very upset when she is suspected of stealing. Nelly doesn't believe it for a second, and is hurt by Samantha's doubt, so both girls work together and solve the mystery of who really took the Blue Star Sapphire. When they solve it and clear their tutor, Grandmary and the Admiral reward them by adding Ireland to the agenda. ( )
