At nineteen, Gwen Arnold left her office job to volunteer for the WAAF. She was trained in the operation of top secret Radio Direction Finding (RDF) equipment, later known as "Radar". Posted to Bawdsey Manor in Suffolk, she and her fellow WAAF RDF operators were responsible for tracking the movements of aircraft and shipping across the North Sea. Despite long working hours, often in uncomfortable conditions, they carried out their orders with dedication and enthusiasm. But they were also young and high spirited, managing to find time for fun and romance. The highs and lows of wartime life and love are recalled with great affection in this honest and entertaining memoir.
