From John Dickson Carr to Ellery Queen, we now move to the last of our look at the scientific detectives on radio - the master himself, Sherlock Holmes, as written by Anthony Boucher (right) and Denis Green. Iâll do a little comparing to the Edith Meiser version of Holmes too.

Continuing the examination of the detectives using the deductive process, a look at the authors Fred Dannay and Manfred Lee, aka Ellery Queen and their famous detective. We'll follow their connection to last week's author John Dickson Carr and hear an episode that while not from the first year (the hour long series) reflects the hour long series since the originals are lost to time. This is from The Ford Theatre and stars the original Ellery Queen Hugh Marlowe (right).

This week concludes my focus on John Dickson Carr. A look at a radio play based upon his Colonel March detective stories (written under the pseudonym Carter Dickson) without, unfortunately, the Colonel. "Five Canaries in a Room" starring Ona Munson (right) is based upon his Colonel March short story "The Crime in Nobody's Room." This version has been Americanized and was written by Carr himself but without Colonel March. Instead we have an Inspector Braddock.
