Cast in doubt

**From Amazon.com:**

While the tumultuous 1970s rock the world around them, a collection of aging expatriates linger in a quiet town on the island of Crete, where they have escaped their pasts and their present. Among them is Horace, a gay American writer who fears he has finally reached old age. Friends only frustrate him, and his youthful Greek lover provides little satisfaction. Idling his time away with alcohol and working on a novel that he will never finish, Horace feels closer than ever to his own sorry end.

That is, until a young, enigmatic American woman named Helen joins his crowd of outsiders. In Helen, Horace discovers someone brilliant, beautiful, and stubbornly mysterious — in short, she becomes his absolute obsession.
