A Case for Dr. Morelle was a captivating 13-episode British Old Time Radio show that aired on the BBC Light Programme from April 23 to July 16, 1957. Created by Ernest Dudley during World War II, the show revolved around the acerbic and eccentric criminal psychologist Dr. Morelle, played by Cecil Parker, and his devoted secretary Miss Frayle, portrayed by Sheila Sim.

Set in 221b Harley Street, London, the series showcased Dr. Morelle's unique talent for using psychological profiling to solve complex murder cases. Often challenged by the interruptions of his secretary, Dr. Morelle relied not on physical evidence but his understanding of the human mind to reveal the true culprit in each self-contained story.

Audiences appreciated the witty banter between Dr. Morelle and Miss Frayle, which provided a light-hearted touch to an otherwise serious drama. With a total of thirteen engaging episodes, A Case for Dr. Morelle remains a classic radio series from the 1950s, demonstrating the power of criminal psychology and deductive reasoning.
