Happy 4th of July and a happy 250th birthday to the USA! In honor of this momentous occasion, I'm sharing an encore presentation of four American history mysteries.

Henry Fonda recreates his role of Young Mr. Lincoln in a radio version of the classic film on Academy Award (originally aired on CBS on July 10, 1946). Honest Abe is a lawyer who must clear his wrongfully accused clients of murder. Lee Bowman plays Allan Pinkterton, one of America's most celebrated detectives, as he investigates a case of robbery and murder in "The Pinkerton Man" from The Cavalcade of America (originally aired on NBC on November 18, 1946). A recently released convict falls in with a gang that forges correspondence from historical figures in "Letters from Aaron Burr" from The Whistler (originally aired on CBS on November 20, 1949). And "the man with the action-packed expense account" hunts for a stolen original copy of the Gettysburg Address. Bob Bailey stars as Yours Truly, Johnny Dollar in "The Meek Memorial Matter" (AFRS rebroadcast from March 3, 1957).
