The Devil's Game, by Poul Anderson

Anybody ever read this? There must be a Poul Anderson fan or two in here. Anyone? Anyone? That is the correct spelling of his first name, by the way, P O U L. Notice that O is at the opposite side of the keyboard from A, soooo that's not a typo. I think the name might be Danish.

Anyway, the story is sort of a cross between the movie The Legacy (1978) and the TV show Survivor. The book I'm talking about came out a long time ago, in the late 70s or early 80s. It's about a bunch of people who get called to a remote island in the Caribbean, to take part in a contest overseen by an eccentric millionaire who is friendly with an entity who seems to be some kind of demon.

It's a pretty old book, but I just thought I'd mention it in case anyone here is a particularly huge fan of The Legacy, Survivor, or Poul Anderson.
