During World War II, Dickie Metcalfe volunteered as a spy for MI5, using his father's connection with Sir Vernon Kell to gather information about weapons and arms deals. He became BALLOON, a sub-agent of double agent TRICYCLE's Yugoslav spy ring, and collaborated with the co-inventor of the Bren gun to develop a new submachine gun for British forces. After the war, he continued to compete in motor racing until shortly before his death. This book examines his success as a double-cross agent using official documents as a primary source.

Dickie Metcalfe was a unique secret agent, defying the conventions of his time. Unlike many others who were part of the Double Cross System during World War II, he did not defect or succumb to blackmail. Instead, he volunteered his services through his father's connection with Sir Vernon Kell, the first Director of MI5. Having recently been cashiered from his infantry regiment, Metcalfe had a ulterior motive: by providing MI5 with valuable information about weapons and arms deals in his new profession as an arms dealer, he hoped to regain his commission.

Metcalfe became a sub-agent of double agent Tricycle's Yugoslav spy ring, operating concurrently with his espionage activities. He collaborated with the co-inventor of the Bren gun to develop a new submachine gun for British forces. After the war, he continued to excel in motor racing, competing until shortly before his passing. This book explores Metcalfe's remarkable career as a double-cross agent, utilizing official documents as primary sources.

In addition to his exceptional intelligence and daring, Metcalfe possessed a larger-than-life personality. He was charismatic, charming, and fiercely loyal to his friends and colleagues. His success as a double-cross agent in the eyes of both the British and German masters is a testament to his skill and determination.

Metcalfe's story is a fascinating glimpse into the world of espionage during World War II. His determination to serve his country, even in unconventional ways, and his ability to navigate the complex web of espionage make him a memorable character in history. This book provides a detailed account of his life and career, shedding light on the lesser-known aspects of his remarkable journey.
