Radio's longest-running private detective wasn't a smart-mouthed, gun-toting wise guy. He was the gentle, dignified, soft-spoken Mr. Keen. Bennet Kilpack stars as the intelligent investigator in this 16-episode collection.

The "kindly old tracer" didn't get into gunfights with thugs on foggy waterfront nights, he simply solved crimes...with a dogged determination. And he was always accompanied by his dense-but-loyal sidekick Mike Clancy (Jim Kelly). Join them as they uncover secrets and crack cases.
