Book 11: Beware the Headless Horseman!

Word of Malcolm and Dandy's work as ghost hunters has spread around the neighborhood! Mr. Gable from the local horse stables has put in a call to get the boys to rid his stables of a headless ghost. The boys consult Washington Irving's The Legend of Sleepy Hollow to see how to handle a situation like this. It'll take a little imagination and some help from Dandy's new girlfriend to zap this horse-riding spirit!
