Trick or treat! It's time for the annual Down These Mean Streets Halloween Special! In this king-sized bonus show, we'll hear a parade of stories - both spooky and silly - designed to get you in the spirit of the season. First, big screen horror legend Boris Karloff lends his voice to "The Corridor of Doom," a thriller from Inner Sanctum Mysteries (originally aired on CBS on October 23, 1945). The Great Gildersleeve attends a Halloween party (originally aired on NBC on October 29, 1947) and a Halloween prank backfires on Henry in The Aldrich Family (originally aired on NBC on October 30, 1940). Then, it's ghosts vs. gumshoes in a pair of old time radio mysteries. Michael Shayne finds a dead body in a haunted house in "The Ghost of Moccasin Hill" (originally aired on Mutual on April 9, 1945), and a ghost may be responsible for a murder in a syndicated adventure of Boston Blackie. The Origin of Superstition tells us the story of the Boogey Man in a syndicated show from 1935, and Favorite Story dramatizes Washington Irving's classic "The Legend of Sleepy Hollow." Dorothy McGuire reprises her screen role as The Screen Director's Playhouse adapts "The Spiral Staircase" (originally aired on NBC on November 20, 1949), and Herbert Marshall makes a monster in a Suspense production of "Frankenstein" (originally aired on CBS on November 3, 1953).
