A snowbound group of people in the north woods must deal with a supernatural killer unleashed by a seance they hold. Locked rooms and impossible murders seem to be explainable only by believing that the dead can come back to take revenge on the living. Footprints that begin and end in the middle of unbroken snowfields, the appearance of a Wendigo that can swoop down on its victims, someone killed by someone possessed by a dead man -- these are some of the puzzles adventurer Rogan Kinkaid is faced with in this classic whodunit/howwasitdun. (Also worth seeking is Talbot's first novel with Kinkaid, "The Hangman's Handyman." Not as atmospheric as "Rim," it features a nice puzzle concerning an ancient curse.)
