A detailed look at UK-US intelligence through a personal lens based on working uniquely for UK intelligence as a British citizen and US intelligence as a US citizen.

UK/US intelligence and the wider Five Eyes community of Canada, Australia and New Zealand is primarily about one main thing: Relationships. In this remarkable book, Anthony Wells charts fifty years of change, turmoil, intense challenges, successes and failures, and never-ending abiding Five Eyes relationships. He traces the development of institutions that he firmly believes have sustained, and indeed may have saved, Western democracies and their allies from those ill disposed to the value system and culture of our nations. More than a chronology of the UK/US intelligence community during this fifty-year period, it is also a personal insight into key relationships and the abiding strength of the United States and the United Kingdom and its Five Eyes allies relationships. The author is the only living person to have worked for British Intelligence as a British citizen and US Intelligence as a US citizen. As a fully trained and accredited security officer for two US intelligence organizations, Anthony has relied on his own extensive unclassified collection of papers, personal notes and diaries, as well as his family library for source material to create this book.

“Few people are as uniquely well equipped as Anthony Wells to write an account of these close and special relationships. His penetrating and informed analysis offers us all hope for the continuance of an alliance which makes the world a safer place." —Vice Admiral Sir Jeremy Blackham, Knight Commander of the Bath, editor, The Naval Review.

"This is a fascinating insider’s account of the origin and evolution of the more than fifty-year close intelligence sharing relationship called the 'Five Eyes' Community - the United States, the United Kingdom, Canada, Australia, and New Zealand. Especially pertinent is the chapter on current and emerging threats and their impact on intelligence collection and analysis by the 'Five Eyes'."

"It is clear from reading the book that Wells has a prolific mind and had a fascinating career. His position integrated into US intelligence had no predecessor nor a successor. As Between Five Eyes has largely a naval focus it will be of most interest to those interested in naval intelligence. But its breadth of topics is far greater."

"This reviewer...highly recommends that every Active Duty/Reserve/Retired US Navy intelligence officer and senior intelligence specialist read this comprehensive history of the Five Eyes Community."

"Those less familiar with intelligence agencies will likely enjoy the discussion and I would recommend it to those just beginning their historical journey into global intelligence practices and strategies."

“…an excellent summary of a 75 year history of intelligence sharing between the United States, United Kingdom, Canada, Australia and New Zealand from World War II to present.”

"Especially pertinent is the chapter on current and emerging terrorist and related threats and their impact on intelligence collection and analysis by the 'Five Eyes'."
