"MI5 is arguably the most secret and most misunderstood of all government departments. Its enigmatic title - much more than its proper name, the Security Service - stands in the public mind for the dark world of the secret services in general. In reality it has a very specific brief: counter-intelligence. Its object is to combat espionage, sabotage and subversion directed against the UK. Nigel West's book traces the history of MI5 clearly and accurately from its modest beginnings in 1909 until 1945. Many of its operations both at home and abroad are described for the first time."--Source : inconnue.

The author of GCHG describes covert missions that “are worthy of spy fiction, but the entire book is utterly fascinating and informative. Brilliant!” (Books Monthly) Written by the renowned expert Nigel West, this book exposes the operations of Britain’s overseas intelligence-gathering organization, the famed Secret Intelligence Service, MI6, and traces its origins back to its inception in 1909. In this meticulously researched account, its activities and structure are described in detail, using original secret service documents. The main body of the book concerns MI6’s operations during the Second World War, and includes some remarkable successes and failures, including how MI6 financed a glamorous confidant of the German secret service; how a suspected French traitor was murdered by mistake; how Franco’s military advisors were bribed to keep Spain out of the war; how members of the Swedish secret police were blackmailed into helping the British war effort; how a sabotage operation in neutral Tangiers enabled the Allied landings in North Africa to proceed undetected; and how Britain’s generals ignored the first ULTRA decrypts because MI6 said that the information had come from “a well-placed source called BONIFACE.” In this new edition, operations undertaken by almost all of MI6’s overseas stations are recounted in extraordinary detail. They will fascinate both the professional intelligence officer and the general reader. The book includes organizational charts to illustrate MI6’s internal structure and its wartime network of overseas stations. Backed by numerous interviews with intelligence officers and their agents, this engaging inside story throws light on many wartime incidents that had previously remained unexplained. “[An] extraordinary book.” —The Daily Telegraph “Fascinating reading.” —Firetrench

The author of The Kompromat Conspiracy shares the history of MI5, from its beginnings in 1909 to 1945 and its role in the Second World War. MI5 is arguably the most secret and misunderstood of all the British government departments. Its enigmatic title—much more than its proper name, the Security Service—stands in the public mind for the dark world of the secret services. In reality it has a very specific responsibility: counterintelligence. Its purpose is to combat espionage and subversion directed against the UK. Nigel West’s book traces the history of MI5 from its modest beginnings in 1909 until 1945, focusing on the important role it played in World War II. This includes the story of the sixteen enemy agents rounded up in Britain who were either hanged or shot; the manipulation of the Axis espionage networks by the use of “turned” Abwehr agents (the famous Double Cross System) and the all-important check on its success provided by the intercepted German signals decoded at Bletchley; and the various deceptions practiced on the German High Command. Laced with true anecdotes as bizarre and compulsively readable as any John Le Carré novel, this book is the fruit of years of painstaking research. West has traced and interviewed more than a hundred people who figure prominently in the story: German and Soviet agents, counterintelligence officers, and even more than a dozen double agents. In this newly revised edition, Nigel West details the organizational charts which show the structure of the wartime security apparatus, in the most accurate and informative account ever written of MI5 before and during the Second World War.
