It's the witching hour - well, closer to two witching hours, to be precise - for old time radio detectives in this week's episode. We've got four mysteries involving witches just in time for Halloween. First, an author plagued by a witch's hexes seeks the help of Nick Carter in "The Witch of Donderberg Mountain" (originally aired on Mutual on April 22, 1945). Next, a witch at a Halloween party sees danger in Boston Blackie's future. Then, Casey, Crime Photographer investigates the murder of a male witch in "Witchcraft" (originally aired on CBS on February 19, 1948). And finally, Sam Spade is hired to act as security for a Halloween party in "The Fairley Bright Caper" (originally aired on CBS on October 31, 1948). Want more spooky sleuthing for Halloween?
