Two days after the start of the 1941 invasion of Malaya, Captain Patrick Stanley Vaughan Heenan, a New Zealander serving in the Indian Army, was caught sending secret codes to the Japanese. The authorities ordered an immediate blackout of all information on his arrest, and the secrets he betrayed were ordered to be suppressed for 100 years. This book looks at these secrets and how they enabled the Japanese to win the air war and then dominate the campaign. It also looks at the reasons behind his behaviour and what caused his guards to become his executioners.
