Oooh, the Howling? Mmmm... werewolves, and nasty ones. It's an oldie but a classic; he was a werewolf and he'd leave little smiley stickers as his calling cards at the scene of his killings. Police didn't know he was one of the werewolves though. I love me some mean, nasty, gruesome type werewolves....
But I didn't want you to think I was ignoring it either.
