Curlie Carson Listens In

A resourceful teenage radiophone operator notices repeated interference with coast-to-ship messages and, with colleagues, traces a puzzling set of coded broadcasts that mention a map, an airplane, a ship, and treasure. The investigation moves from tower-room sleuthing to a cross-country and then sea voyage prompted by a mysterious chart, encountering storms, a ghostly sighting, a wreck, urgent S.O.S. signals, a confession, and a revealed secret that links the map to a rescue and recovery. The narrative combines technical radio procedure, suspenseful pursuit, and maritime adventure, structured as a sequence of escalating discoveries and chases that resolve the mystery of the broadcasts.
