Moonflowers — Helen Haught Fanick

Cora Taylor disappeared 54 years ago, and no trace of her was ever found. Now her sister has enlisted the help of Andrea Flynn and Kathleen Williamson in finding out what happened to Cora. The two are known for their ability to solve cases that are puzzling the police, and Mary Taylor is confident they can uncover Cora's fate. Andrea and Kathleen are doubtful they can find the answer Mary is looking for, but they decide to try. They start researching, and the case becomes more complicated when someone who was close to Cora, a likely suspect in her disappearance, is murdered. The more the sister sleuths investigate, the more complex the situation becomes. How did expensive jewelry end up in Cora's possession? Who knew moonflowers were poisonous and stole them from Andrea's deck? Was the Mafia involved somehow, and what about the accusations against a jealous wife? And when a second suspect is murdered, are the sisters and Mary in danger, too?
