CBS RADIO MYSTERY THEATER, “The Great Brain,â€, starring Gordon Heath, with  E.G. Marshall, host. A scientist wagers he can use his brain power to escape from the stat pentitentiary’s solitary confinement cell.

Dr. Gregory March, who never played chess in his life, defeats the grandmaster champion in four of five matches. “I’m just trying to show that anything is possible with human brain power,â€ he says. To prove his thesis further, he wagers with two of his colleagues that he can break out of the best-guarded cell in the state prison in no more than a week. All he asks the warden is for some tooth powder, one five-dollar and two ten-dollar bills, and permission to have his shoes shined before he enter the cell.
