A Whiff Of Garlic — David Hunter

Veteran detective Doyle Griffin pays little attention to the news that someone has broken into the Museum of Legends in the nearby tourist town of Gatlinburg, Tennessee, and has stolen the werewolf exhibit--a silver crucifix and six silver bullets. Then victims start turning up in his own county, beheaded, and with silver bullets in their hearts, canine hair on their clothes, and garlic stuffed into their body cavities. The detective turns to Sarah Trinkle, his girlfriend, who is a Wiccan priestess and a licensed psychotherapist, for help with the case.

Who did it? Was it the professed werewolf who raises and sells wolves? Was it the Indian craftsman, a former police officer, who made the silver bullets? Or was it the taxidermist with strange things in his freezer? You'll still be wondering when you get to the last chapter.
