Ransom at Sea

With a relaxing few days in mind, Miss Emily Charters signs up for a four-day seniors' cruise of the Great Lakes organized by her church. In the company of her friend and housekeeper, Lynn Francis, Charters and the other seniors set sail from Chicago, but while the waters on the lake are calm and predictable, her fellow passengers are not. However, a little tension is the least of the problems when one of her fellow passengers is found horribly murdered in her cabin.
