Plot
The Five are camping on Billycock Hill, near the farm of Toby, a boy who loves jokes and pranks. When Toby's cousin Jeff, a Royal Air Force pilot, and Jeff’s friend Ray are reported to have defected and stolen the newest aeroplanes, the Five and Toby are shocked. The media later reports Jeff and Ray crashed their planes and drowned at sea. Toby refuses to believe that Jeff was a spy, as he had always seemed a trustworthy man. The Five attempt to comfort the distraught Toby. Later that day, Toby's younger brother Benny's pet piglet, Curly, appears with a message leading the children to find Jeff and Ray imprisoned in Billycock Caves. The children then rescue the pair.
