The Adventures of Ellery Queen began on CBS radio in 1939 as a one-hour program starring Hugh Marlowe as Ellery, Ted de Corsia (replacing Howard Smith) as Sgt Velie, and Marion Shockley as Nikki Porter. It was cut back to 30 minutes about half-way through its run.

After more than a year off the air the show returned in 1942, now on NBC and with a mostly new cast:

Ellery: Carleton Young
Inspector Queen: Santos Ortega
Sgt Velie: Ted de Corsia
Nikki Porter: Marion Shockley

EQ: Hugh Marlowe
Inspector Queen: Santos Ortega
Sgt Velie: Ted de Corsia
Nikki Porter: Charlotte Keane

Australian radio remade a number of US scripts. Charles ‘Bud’ Tingwell took the EQ role, and Wendy Playfair was Nikki:
