The Haunted Mustache (Night Frights, Bk. 1)

Wolver Hollow is not a normal town. The adults are too busy shuffling off to work at the old coffin factory to notice or care, but the kids know all about monsters, ghosts, and strange lights in the sky. Strange things happen in Wolver Hollow. Creepy things.

But fifth graders Parker and Lucas are determined to debunk one of Wolver Hollow’s legends: Over a hundred years ago, Bockius Beauregard was vaporized in an unfortunate accident and all that remained was his magnificent mustache. People say it returns every year, on the anniversary of Bockius’s death, seeking a lip to claim as its own! When the boys try to prove the story is fake, the find more than they bargained for.
