Truman Capote was already a celebrity by the time Breakfast at Tiffany's was released in
1958. It was written at the end of what he called his second cycle of writing which began with his first published novel, Other Voices, Other Rooms. Although it was never assumed by the critics at the time, Breakfast at Tiffany's was to become one of the most famous and influential works Capote ever wrote. I would put it second only to his non-fiction novel, In Cold Blood which emerged in his third cycle.
