Bill Stroud thought his life was over. His wife and son were dead, his daughter and his son-in-law had disappeared at sea while on passage toward the Caribbean, and he had lost interest in everything, including his only hobby: offshore sailing. But then a friend sends him a picture postcard of a marina in St. Thomas, and he is almost sure that one of the boats in the background is his daughter's. When he discovers that all her traveler's checks were cashed a week after she sailed on that final, ill-fated cruise, he knows there is one more voyage he must make.
