Jessica's plans to enjoy a relaxing cruise to Alaska are dashed when her friend Kathy Copeland joins her. Kathy's sister vanished from the very same vessel on a prior voyage, and though Wilimena often disappeared on flights of fancy, Kathy is convinced that this time is different.
The Copeland sisters had a notorious aunt -- the most famous madam in Alaska's history, who, rumor has it, struck it rich during the gold rush. It seems daring Wilimena has gone searching for the treasure and may have attracted the wrong kind of attention. Suddenly Jessica's vacation becomes a challenging investigation. And before Kathy and she are even halfway to their destination, Jessica senses that someone is watching every move they make.
