Triggered by the disappearance of a brilliant young professor, this mystery takes the Hardy Boys first to Kenworthy College, where they find a puzzling message on an examination paper. But then their pal Chet Morton and buddy Biff Hooper turn up a clue that sends the young detectives in another direction, to the Honeycomb Caves.
After many dangerous encounters, Frank and Joe discover a powerful searchlight on one of the craggy caverns along the seacoast. In the white glare of the searchlight, the startling secret of the cave is dramatically revealed.
"Filled with action and plot twists, the mystery is ably read by Bill Irwin. His delivery is soft, but he has enough variety to keep the listener's interest. The sound effects and music are also appropriate for the production." (AudioFile)
