All by Myself, Alone (Broché)

Fleeing the humiliating arrest of her husband-to-be, Celia Kilbride, a jewelry expert, hopes to escape from public attention by lecturing on a brand-new cruise ship—the Queen Charlotte. On board she meets eighty-six-year-old "Lady Em." Immensely wealthy, Lady Em plans to wear her priceless emerald Cleopatra necklace, which, according to legend, placer a deadly curse on whoever brings it to sea. The Queen Charlotte is three days out and Lady Em is found dead—and the necklace is missing.

Or is it the young lawyer who tried to persuade Lady Em to return the necklace to Egypt ? The list of suspects is large and growing. Celia does not realize that her friendship with Lady Ein has not escaped the notice of the killer.
With the help of her new friend, Willy and Alvirah Meehan, she must avoid the danger that awaits her before the ship reaches its final destination...
