Killer Fruit

"Are you familiar with the term "killer fruit"? It's a certain kind of queer who has Freon refrigerating his bloodstream. Diaghilev, for example. J. Edgar Hoover. Hadrian."
     --Truman Capote, Answered Prayers

Answered Prayers is an uncompleted novel.  Excerpts were published in Esquire Magazine in 1976, with the result that Capote was alienated from all of his elite social contacts in New York.

I'm thinking of using "Killer Fruit" as the title for a true crime book.
