Moon of the Wolf (1972) is a really underappreciated film in the werewolf sub-genre

Based on a novel by Leslie H. Whitten and directed by Daniel Petrie, Moon of the Wolf is a murder-mystery of the wolfish variety that also operates as a capsule of small town life. After a woman turns up dead in the woods, the residents of a rural Louisiana town believe that a pack of wild dogs are responsible. However, Sheriff Aaron Whitaker (David Janssen) suspects that a person is behind the crime, only to discover later on that the culprit might be a werewolf.
