Hurry, hurry, hurry - come to the midway for four radio mysteries set at the carnival. A fortune teller predicts her own murder in a syndicated adventure of Boston Blackie starring Richard Kollmar. Then, a carnival dancer marries a wealthy admirer and then schemes to get rid of him in "The Brass Ring" (originally aired on CBS on September 16, 1946). Sam Spade tries to save a carnival performer from marriage to an infamous widower - to be followed by a quick funeral - in "The Bluebeard Caper" (originally aired on CBS on August 8, 1948). And we take flight with Superman to save a carnival from an unscrupulous rival owner in "Death Rides the Roller Coaster" (originally aired on ABC on December 3, 1949).

It's not just adults who need a good detective. Our heroes this week come to the aid of kids in trouble. First, Dan Holiday helps a boy find a lost astronomer in "Archimedes and the Roman" from Box 13. Next, Philip Marlowe is hired to find the missing uncle of a newsboy in "The Kid on the Corner" (originally aired on CBS on December 3, 1949). Finally, Johnny Dollar believes the life of a teenage girl is in danger when she stands to inherit a fortune in the five-part mystery "The Matter of Reasonable Doubt" (originally aired on CBS between May 28 and June 1, 1956).

Our heroes this week encounter hypnosis and meet those who have fallen under its spell and who have used it to try and conceal their crimes. First, Boston Blackie suspects a woman's murder confession was driven by hypnosis rather than guilt. Then, a woman is hypnotized to help solve a murder in "Cupid Can Be Deadly" from Crime Club (originally aired on Mutual on October 16, 1947). In "The Voice of Darkness," Chandu the Magician investigates a bombing where the eyewitness was hypnotized into losing her memory (originally aired on Mutual on April 14, 1949). And finally, Bob Bailey stars as George Valentine in "Eleven O'Clock" from Let George Do It, where a woman's recent odd behavior may be tied to the experiments of a psychology professor (originally aired on Mutual on July 17, 1950).

As Americans head to the polls to pick a president, we'll hear some old time radio mysteries centering on the seedier side of the political process. Fortunately, The Green Hornet is on hand to keep things safe for democracy and to deliver a decisive blow against the crooked machines who try to get corrupt politicians elected. We'll hear the Hornet and his loyal sidekick Kato in "Votes for Sale" (originally aired on Mutual on October 9, 1940), "Ballots and Bluff" (originally aired on Mutual on November 1, 1945), and "Election Boomerang" (originally aired on Mutual October 15, 1952). Plus, we'll hear "Final Returns," a story from The Whistler about a politician who decides to vote his domineering wife out of his life permanently (originally aired on CBS on October 29, 1945).

Get ready for thrills, chills, and spills with trick-or-treat tales both scary and silly in the annual Down These Mean Streets Halloween special! Ray Milland reprises his big screen role as The Screen Director's Playhouse presents "The Uninvited" (originally aired on NBC on November 18, 1949). Then, two radio gumshoes face off against things that go bump in the night: The Saint in "The Ghosts Who Came to Dinner" (originally aired on NBC on April 8, 1951) and Barrie Craig, Confidential Investigator in "Ghosts Don't Die in Bed" (originally aired on NBC on September 7, 1954). J. Carrol Naish stars in a heartwarming and hilarious Halloween episode of Life with Luigi (originally aired on CBS on October 30, 1951), and William Conrad leads an expedition in the Himalayas to capture "The Abominable Snowman" on Escape (originally aired on CBS on September 13, 1953). Ozzie and Harriet have a haunted house adventure (originally aired on NBC on October 31, 1948), and Bob Hope recreates his horror-comedy classic in "The Ghost Breakers" from Screen Director's Playhouse (originally aired on NBC on June 14, 1951). Finally, the syndicated anthology The Weird Circle presents one of the classic horror stories - Mary Shelley's "Frankenstein."

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).

Great Scott...600 episodes?! To mark the occasion, I'm on a trip to 221B Baker Street with my favorite radio adventures of Sherlock Holmes. In this super-sized Sherlock special, we'll hear John Gielgud and Ralph Richardson in "A Scandal in Bohemia." Basil Rathbone and Nigel Bruce are Holmes and Watson in "The Notorious Canary Trainer" (originally aired on Mutual on April 23, 1945) and "The Speckled Band" (originally aired on Mutual on November 12, 1945), and then Bruce is joined by Tom Conway as Holmes in "The Adventure of the Tolling Bell" (originally aired on ABC on April 7, 1947). My personal favorite Holmes and Watson - John Stanley and Alfred Shirley - headline "The Laughing Lemur of Hightower Heath" (originally aired on Mutual on October 26, 1947), "The Cadaver in the Roman Toga" (originally aired on Mutual on November 9, 1947), "The Stolen Naval Treaty" (originally aired on Mutual on November 23, 1947), and "The Case of the Sudden Senility" (originally aired on Mutual on January 11, 1948). And finally, it's - appropriately enough - "The Final Problem," with Gielgud, Richardson, and special guest star Orson Welles as Professor Moriarty.
