Jeremy Logan is an "enigmalogist," an investigator who specializes in analyzing phenomena that have no obvious explanation. He travels to an isolated writers' retreat deep in the Adirondacks to finally work on his book when the remote community is rocked by the grisly discovery of a dead hiker on Desolation Mountain. The body has been severely mauled, but the unusual savagery of the bite and claw marks call into question the initial suspicions of a wild bear attack. When Logan is asked to help investigate, he discovers no shortage of suspects capable of such an attack --- and no shortage of locals willing to point the finger and spread incredible rumors. One rumor, too impossible to believe, has even the forest ranger believing in werewolves.
