A tour of historic Savannah, Ga., features the extravagancies and eccentricities revealed in John Berendt's bestseller "Midnight in the Garden of Good and Evil." Included: an 18th-century pirate said to haunt the notorious Pirates' House tavern; Fort Jackson's phantom soldiers; and tales of deceased slaves who frequent the waterfront where they once labored as shipwrights, caulkers and ropemakers.
