Samuel Guy Endore (4 July 1900 - 12 February 1970), born Samuel Goldstein and also known as Harry Relis, was a novelist and screenwriter. During his career he produced a wide array of novels, screenplays, and pamphlets, both published and unpublished. A cult favorite of fans of horror, he is best known for his novel The Werewolf of Paris which occupies a significant position in werewolf literature, much in the same way that Dracula does for fans of vampires. He was nominated for a screenwriting Oscar for The Story of G.I. Joe (1945), and his novel Methinks the Lady . . . (1946) was the basis for Ben Hecht's screenplay for Whirlpool (1949).
I find it almost unbelievable that this was Endore's only published novel before THE WEREWOLF OF PARIS. Ambitious enough in its goals, LIMBO just isn't very good. A tale of a rather unlikable aspiring writer writing a novel is a tough road in the first place and the inevitable merging of fiction and life has to be especially engaging to avoid cliché. The mildly ironic tone doesn't help and shows only a trace of the wit and sophistication of WEREWOLF. A curiosity at best.
