“This is the most compelling analysis of the new evidence!” –Oleg Kalugin, former KGB General and Chief of Counterintelligence“Experts in the art of espionage, West and Melton deliver a brilliant historical thriller on the most consequential and highest profile of Stalin's multitude of targeted political assassinations. Their newly uncovered archival research exquisitely lifts the veil on a sophisticated Soviet global spy operation with tentacles reaching into the U.S. A must-read for understanding how the Trotsky assassination spawned the Kremlin's playbook for creating a dictatorial regime full of fear and subjugation, which Putin follows to this day.” –Daniel O. Hoffman, retired CIA Senior Clandestine Services Officer"Readers may be excused for mistaking the engrossing account of THE ASSASSINATION OF LEON TROTSKY for a spy novel. This compelling narrative combines espionage intrigue, operational execution and never before documented evidence to establish the how and why of Stalin’s obsession with destroying his most feared rival. Melton and West meticulously reconstruct the decade-long conspiracy on three continents to track, harass and kill their target. For today’s audience, the relentless pursuit of Trotsky by Stalin’s operatives will mirror 21st century assassinations by Putin’s Russia. THE ASSASSINATION OF LEON TROTSKY presents a compelling example of how the best history informs the present." –Robert Wallace, retired Director, CIA Office of Technical Service“For those who have worked in the intelligence profession, this book reads less like history and more like a case file. H. Keith Melton and Nigel West have produced a meticulously researched account, informed by decades of experience in the world of espionage. The authors illuminate how nation-states can weaponize tradecraft, access, and human relationships, with profound human consequences. It is a powerful reminder that these methods did not disappear—they continue to evolve.” –Alan E. Kohler, Jr., retired Assistant Director, Counterintelligence Division, FBI
