Can you hear something peculiar?" Jon said quietly. "A high thin noise." "Yes, I can," whispered Penny. "It's everywhere!" Now there was a faint glow above the land. The whining noise increased. Then Jon pointed with a shaking hand. Something - an object such as they had never seen before - was rising swiftly into the night sky . . . Penny's parents, home from abroad for a spell, suggest Penny and Jon invite along the Mortons and Peter to share their holiday in a lonely house on Dartmoor. And to the Lone Piners' amazement they see strange flying objects there. Are they flying saucers from outer space - or are they something to do with the mysterious Secret Station high on the moor? What is the sneaky little bird-watcher Green up to? And just what is his connection with the pleasant but suspicious manservant Donaldson? And when Jon and David see a sinister foreign helicopter harassing the mysterious man living rough on the moors, the plot thickens. As usual with their thirst for adventures the Lone Piners are in the thick of things - determined to find out all about the mysterious saucers - whose secret is finally revealed in a thrilling climax. This is the eighth exciting story in the Lone Pine Adventure series, and like all the others it is a complete story in itself.
