Written in prison in South Africa, Ireland and the United States, Enemy of the Empire was originally a device for keeping sane in a situation of extreme boredom and oppression. A trained aviation engineer, up-to-date with the latest technology, Eamon McGuire worked in countries that were extricating themselves from the bonds of empire such as Kenya and Malaysia. His mission was to keep ahead of the British army in terms of weapons and detection by procuring and designing systems. His activities forced him to go on the run, hiding in remote parts of Africa and eventually ending up in war-torn Mozambique. He was captured by the CIA in South Africa and subsequently spent several years in various prisons where he started to write what became the basis of this book.
