Episode 44 aired on CBS Radio June 1, 1943. Starring veteran actor Donald Crisp. Banquo’s Chair” is the story of the ex-chief of England’s Criminal Investigative department, one William Brent, and the unusual method he devises to extract a confession from a murderer some 20 years after his being set free for lack of evidence. It was the only case in Brent’s case file where his quarry had escaped his clutches. Brent, much like Sherlock Holmes in many ways, is brilliant, cold, and calculating, with an ego that prevents him from letting go this one stain on his otherwise perfect crime-solving career.
