The first book in the “Spies Are People Too” series. "Variation of Loyalties" is a spy novel written in the best traditions of the genre. A dynamic plot involving political intrigue and a hidden war within the KGB itself. A charming and charismatic young KGB officer Lazarev masterfully carries out tasks, bypasses the enemy, checking every step and still balancing on the edge of the abyss. All this makes the book fascinating, exciting and incredibly interesting. The events take place in the early 60s of the last century. This story uses real facts, but many of them are controversial and do not have documentary evidence. The book does not pretend to be a documentary; it is an action-packed novel about events of the past.
