We'll hear an on-air recreation of Hitchcock's Shadow of a Doubt, featuring Joseph Cotten in his big screen role. It originally aired on Academy Award on CBS on September 11, 1946.

Larry Thor stars as Detective Danny Clover as he walks “the gaudiest, the most violent, the lonesomest mile in the world” in Broadway is My Beat.

Then, we'll hear "The Harry Foster Murder Case" (originally aired on CBS on May 5, 1951).

Before his death in 1951 at age 43, Wally Maher made a name for himself as a versatile, in-demand radio actor. Equally adept at comedy and drama, Maher could be heard in regular roles on shows all over the dial. We’ll hear him as Sgt. Matt Grebb in “Eddie Gaynor Framed for Murder” from The Line-Up (originally aired on CBS on July 20, 1950) and as Michael Shayne, Private Detective in “Judge Thorman Shot” (originally aired on Mutual on January 14, 1947).

First, Marlowe tackles the case of “The Eager Witness” (originally aired on CBS on August 27, 1949), and then “The Deep Shadow” (originally aired on CBS on March 21, 1950).

Long before Dragnet, Gang Busters brought true crime to radio. Over its two decade run, the series presented stories of dangerous criminals and the determined police officers who brought them to justice. Producer Phillips H. Lord pulled cases from state and local law enforcement agencies and presented them in one of radio’s most down to earth crime dramas. Its memorable introduction - with the wail of sirens and a hail of bullets - gave rise to the expression “coming on like Gang Busters.” We’ll hear “The Case of the Incorrigible Killer,” first aired on ABC on October 9,  1948.

William Gargan wasn't a great private eye in real life, but he played a mean one on radio. Years after he supported himself checking credit and shadowing suspects, Gargan starred as several radio detectives including Barrie Craig, Confidential Investigator. We'll hear the actor as Craig in "The Lost Lady" (originally aired on NBC on June 14, 1953) and "Ghosts Don't Die in Bed" (originally aired on NBC on September 7, 1954).

Nick and Nora Charles - Dashiell Hammett’s husband and wife detective duo from The Thin Man - charmed readers and later moviegoers with their flirtatious and funny approach to cracking a case of murder. In 1941, Nick and Nora moved radio in The Adventures of The Thin Man. This blend of comedic banter and crime-solving was a long-running hit with listeners, and it ran on radio for nearly a decade. We’ll hear Les Damon as Nick and Claudia Morgan as Nora in “The Case of the Wandering Corpse,” originally aired on CBS on October 10, 1943.

One of radio’s men of a thousand voices, Paul Frees was heard all over the dial during the Golden Age of Radio, as Boris Badenov on television, and as the ghostly host at Disney’s Haunted Mansion. In honor of this versatile, talented actor’s birthday, we’ll hear him in two episodes as The Green Lama, the pulp hero who came to the airwaves in his own detective series. Frees stars as the Lama, aka Jethro Dumont, in “The Million Dollar Chopsticks” (originally aired on CBS on June 26, 1949) and “The Adventure of the Perfect Prisoner” (originally aired on CBS on August 21, 1949).

Reformed jewel thief Boston Blackie was a debonair detective in his years on radio. Along with his girlfriend Mary Wesley and sidekick Shorty, Blackie used his underworld know-how to catch more unscrupulous thieves and scoundrels. Racing against Blackie to crack the case first was Inspector Farraday of the police, always unsure of Blackie’s conversion to the side of law and order. To celebrate the anniversary of his radio debut, we’ll hear him in a pair of radio mysteries: “The Star of the Nile” starring Chester Morris (originally aired on NBC on July 14, 1944), and “Blackie Steals a Necklace for Charity,” a syndicated episode starring Richard Kollmar.

When Yours Truly, Johnny Dollar came back to the airwaves in 1955 after a brief hiatus, it was reenergized by a new nightly serialized format and a new star in Bob Bailey. Bailey made the role of “the man with the action-packed expense account” his own in rich, complex scripts that could play out five nights a week in a combined hour of airtime. We’ll hear Bailey as Dollar  in all five parts of “The Laughing Matter” (first aired on CBS from June 11 to June 15, 1956).

Jack Webb is back as Sgt. Joe Friday in a two-part episode of Dragnet.

Dashiell Hammett is widely regarded as the father of the hard-boiled school of crime fiction. After his days as a Pinkerton detective, he turned to writing mysteries, and he gave the genre some of its best loved stories, including The Maltese Falcon, The Thin Man, and The Dain Curse. In honor of his birthday, we’ll hear radio adventures of two of his private eyes - Brad Runyon, aka The Fat Man, in “Murder Plays Hide and Seek” (originally aired on ABC on January 2, 1948); and Sam Spade in “The Lawless Caper” (originally aired on CBS on August 29, 1948).

Join Orson Welles as he leads you on a guided tour of The Black Museum, Scotland Yard’s mausoleum of murder.

We’ll hear Welles narrate the syndicated story “The Telegram."

Step into the shoes of the criminal in The Whistler, one of radio’s best mystery anthologies. In tales narrated by the titular sinister storyteller, you’ll follow the culprit as they plot and carry out the perfect crime only to be undone by a twist of fate before the curtain comes down. As the Whistler, Bill Forman narrates stories starring two radio detective stars in roles on the opposite side of the law: Howard Duff in “The Witness at the Fountain” (first aired on CBS on September, 9, 1946); and Gerald Mohr as “The Clever Mr. Farley” (first aired on CBS on November 27, 1949).

In 1952, John Lund became radio’s third Johnny Dollar, and he starred as “the man with the action-packed expense account” for almost 100 episodes in a two-year run. The big-screen star brought a confident, leading man quality to the role and gave Dollar a hard-boiled but world-weary persona. We’ll hear John Lund as Yours Truly, Johnny Dollar in “The Walter Patterson Matter,” originally aired on CBS on December 26, 1952.

We head back to London for another mystery from Scotland Yard and a dangerous, relentless Pursuit. This series let listeners join in on the game of cat and mouse between cop and criminal – “when man hunts man.” Ben Wright stars as the dogged Inspector Peter Black, hot on the heels of England’s most dastardly criminals. We’ll hear him on the job in “Pursuit of the Asiatic Killer,” first aired on CBS on March 11, 1952.

Dick Powell lends his pipes to the role of Richard Diamond, radio’s singing detective. But don’t let his post-crime solving crooning fool you - he can throw a punch and wield a .38 with the best of them. Along the way, he’ll flirt with his girlfriend and frustrate the police a few times before the case is wrapped up. We’ll hear him star in “The Bloody Hat Case” (first aired on NBC on July 2, 1949) and “The Caspary Case” (first aired on ABC on February 2, 1951).

CBS wanted a “Philip Marlowe of the Old West,” and they got that and more in Gunsmoke. One of radio’s finest dramas, Gunsmoke helped to usher in the era of the “adult Western” with mature scripts, unflinching realism, and legendary performances from William Conrad and the rest of the cast. For nearly a decade on radio - and twenty years on television - US Marshal Matt Dillon faced down the violence of the West to keep the streets of Dodge City safe. We’ll hear Dillon fight for law and order in “Shakespeare,” first aired on CBS on August 23, 1952.

In honor of the late Stan Freberg, “Down These Mean Streets” presents a bonus episode showcasing some of the radio work of this legendary comedian.

Then, Freberg takes a dramatic starring turn in “Alibi Me” from Suspense (an Armed Forces Radio Service rebroadcast of an episode from April 20, 1958).

J. Edgar Hoover’s FBI agents captured headlines with their daring pursuits of bank robbers and enemy spies, and their exploits made for thrilling radio adventures. Several radio programs brought the cases of the Bureau to listeners and featured dramatizations of actual FBI case files. We’ll hear special agents on the job in “The Traveling Man” from The FBI in Peace and War (originally aired on CBS on June 10, 1953), and “The Hollywood Frame-Up” from This is Your FBI (originally aired on ABC on February 10, 1950).

Before he protected the innocent on Dragnet, Jack Webb made a name for himself in a pair of hard-boiled detective dramas. The characters he played were miles away from the straight arrow Sgt. Joe Friday. They were down-on-their-heels working stiffs out for a buck and usually getting cheated out of it, working their way through cases full of deceitful dames, angry gunsels, and impatient cops. We’ll hear Webb as Pat Novak For Hire in “Reuben Calloway’s Pictures” (originally aired on ABC on March 13, 1949) and as Jeff Regan, Investigator in “The Man with the Key” (originally aired on CBS on October 2, 1948).

In 1944, Michael Shayne came to radio. Brett Halliday’s red-headed shamus had thrilled readers and moviegoers, and Wally Maher was tapped to bring the character to the airwaves. Maher starred as Shayne (with Cathy Lewis as Shayne’s secretary Phyllis Knight) for the next three years. Maher’s Shayne was cocky and glib, and he liked to use his brains instead of his brawn to crack a case. We’ll hear him in “The Return to Huxley College,” originally aired on Mutual on November 5, 1946.

The radio success of Mr. and Mrs. North convinced CBS to bring the adventures of the crime-solving couple to television. Richard Denning and Barbara Britton starred as Jerry and Pam and moved to take over the radio roles after a year on the small screen. Denning and Britton continued the program’s trademark balance of crime with light comedy simultaneously over radio and on television. We’ll hear the Norths in “The Comic,” an Armed Forces Radio Service rebroadcast of an episode originally aired on CBS on July 7, 1953.

Hercule Poirot, the diminutive, eccentric, and brilliant Belgian detective, has thrilled mystery fans since his first appearances in the novels of Agatha Christie. In 1945, he came to American radio in a series that boasted an introduction by Christie herself. Harold Huber starred as the mustachioed master of deduction in Agatha Christie’s Poirot, and he was perfect as the fastidious investigator. We’ll hear him in “The Case of the Careless Victim,” originally aired on Mutual on February 22, 1945.

We raise a glass to Mickey Spillane, the hard-boiled wordsmith born March 9, 1918. Spillane introduced the world to Mike Hammer, one of fiction’s toughest gumshoes, in 1947, and detective fiction was never the same. The unique blend of sex and violence, powered by Spillane’s terse prose, enthralled readers and led to adaptations on television, the big screen, and on radio. We’ll hear Larry Haines as Mike Hammer in That Hammer Guy in “There’s Something About a Dame” (first aired on Mutual on March 31, 1953) and “What You Don’t Know About Dames” (first aired on Mutual on April 28, 1953).

Craig Rice’s crafty criminal lawyer John J. Malone, a wisecracking counsellor at law, sprang from the pages of mystery novels to radio in The Amazing Mr. Malone. Malone takes tough cases in Chicago, where he does his own leg work to clear his wrongfully accused clients. He’s more of a Paul Drake than a Perry Mason in the way he tackles his cases. We’ll hear George Petrie star as Malone in “Hard Work Never Killed Anyone,” originally aired on NBC on June 1, 1951.

For fourteen films and hundreds of radio episodes, Nigel Bruce brought the most famous sidekick in detective fiction to life. As Dr. John H.

Charles Russell stars as Yours Truly, Johnny Dollar in one of the earliest adventures of "America's fabulous freelance insurance investigator."

We'll hear him in "The Robert Perry Case," originally aired on CBS on March 4, 1949.

Sixty-five years ago this week, radio listeners met Randy Stone, the intrepid Chicago reporter of Night Beat.

The Green Hornet was one of radio's most popular masked crime-fighters, and his exploits came to the big and small screens. We'll hear Al Hodge as the Hornet in "The Corpse That Wasn't There," originally aired on the Blue Network on March 7, 1943.

Big screen villain Dan Duryea takes a heroic turn as Lt. Lou Dana, The Man from Homicide. Dana is a hard-boiled cop who shoots straight and throws a mean punch. His outlook on his job is summed up with his mantra: "I don't like killers." This short-lived series blends the two-fisted pulp persona of a private eye with the dogged cops of police procedurals. We'll hear Duryea as Dana in "The Franklin Kelso Case," originally aired on ABC on July 16, 1951.

Dana Andrews is undercover for Uncle Sam in I Was a Communist for the FBI. Based on the real-life exploits of Communist infiltrator Matt Cvetic, the syndicated series presented espionage dramas of Reds on the homefront and the efforts of the G-men to thwart their nefarious plans. Cvetic's story was adapted for the big screen in an Oscar-winning film and then on radio in this syndicated drama. We'll hear Matt Cvetic on the case in "Treason Comes in Cans."  

Sinners beware - The Saint is on the case! Vincent Price stars as Simon Templar, "the Robin Hood of modern crime" in two radio mysteries.

Sydney Greenstreet settles into the armchair of Nero Wolfe, Rex Stout's gargantuan gourmet and irascible (but brilliant) detective. Wolfe will tackle a case only when his bank account demands it, and even then he farms out the fact-finding to his leg man, Archie Goodwin. Greenstreet stars in two radio mysteries: "The Case of the Impolite Corpse," with Larry Dobkin as Goodwin (originally aired on NBC on December 8, 1950); and "The Case of the Party for Death," featuring Harry Bartell as Archie (originally aired on NBC on February 16, 1951).

Howard Duff was one of radio's brightest stars until the blacklist and "Red scare" paranoia derailed his career.

In 1958, CBS launched a radio version of its hit western television series Have Gun - Will Travel. The radio program was one of the last great dramas of the Golden Age of Radio. John Dehner assumed the role of Paladin, the West Point-educated hired gun, a gunman for hire who would take on dangerous jobs for the right price. This blend of western adventure and private eye mystery was just as engaging as its television brother. We'll hear Paladin in "Strange Vendetta," originally aired on CBS on November 23, 1958.

Damon Runyon remains one of America’s unique storytellers. His tales of 1920s New York have a language and style all their own, and his colorful characters include gangsters, gamblers, and average guys down on their luck. Runyon’s distinct voice came to radio in The Damon Runyon Theater, a series produced by Alan Ladd. We’ll hear John Brown star in “What, No Butler?” from the syndicated series.

Dick Powell transformed his career with his dynamic performance as Philip Marlowe and he left his days as a baby-faced crooner behind.

Glenn Langan stars as Drake in this series that originally aired on Mutual before it was repackaged for syndication. We’ll hear the syndicated episode “The John Crain Murder.”

Natalie Masters is back as San Francisco's loveliest private investigator, Candy Matson. One of radio's most famous girl detectives, Candy cracks cases with the best of them.
