Washington Irving's "The Legend of Sleepy Hollow" is one of the best-known works of American literature. But what other myths lie hidden behind the landscape of New York's Hudson Valley? Imps cause mischief on the Hudson River; a white lady haunts Raven Rock; Major Andre's ghost seeks redemption; and real headless hessians search for their severed skulls. Local folklorist Jonathan Kruk tells these and other tales of the lore of the Hudson Valley the stories that have created an atmosphere of mystery that helped inspire Irving's legend.
