All by myself, alone
(Book)

Fleeing the disastrous and humiliating arrest of her hedge fund executive husband-to-be, Celia Kilbride, a gems and jewelry expert, hopes to escape from public attention and allegations she was a co-conspirator by lecturing on a brand-new cruise ship--the Queen Charlotte. On board she meets "Lady Em" who plans to wear her priceless emerald Cleopatra necklace. Three day sout at sea and Lady Em is found dead--and the necklace is missing. Celia, with the help of her new friends Willy and Alvirah Meehan, who are celebrating their 45th wedding anniversary, sets out to find the killer, not realizing that she has put herself in mortal danger before the ship reaches its final destination.
