In the wake of the Profumo Affair the COI “produced a lively booklet … as part of their educational campaign to improve the awareness of middle and lower grade officials and members of the Armed Forces of their responsibilities in regard of security matters” (Gladden, Civil Services of the United Kingdom: 1885-1970, p166). Includes accounts of notorious cases, tricks of the trade, and helpful advice, “Spies are with us all the time. They are interested in everything, defence secrets, scientific secrets, political decisions, economic facts, even people’s characters in order to recruit more spies” (Preface).
