Season one introduced Inspector Mark Saber of the Homicide Squad and his able assistant, Sergeant Tim Maloney.
But despite the negative reviews, ABC radio ordered a second season of episodes to premiere in the fall of 1952.
Hearthstone of the Death Squad reproduced broadcasts from the two years of CBS Mystery Theatre repackaged as their own series.
In the end, listeners were getting weary of both CBS's Hearthstone and ABC's Mystery Theater and their similarities and neither of the two stories survived the 1952–1953 radio season.
It aired on Fridays prime time at p.m. EST,[1] against CBS's Mama, and NBC's Quiz Kids, and in April 1952 was moved to 9:30 p.m. on Wednesdays.
For the 1952–53 television season, it was retitled Inspector Mark Saber – Homicide Squad and aired on 8 p.m. on Mondays,[1] where it competed against CBS Lux Video Theatre and NBC What's My Name?
