Rory Cormac, "Fakers: A Top-Secret Tale of Phantoms and Forgeries on the Disinformation Front Line" (Oxford UP, 2026) New Books in National Security

Fakers: A Top-Secret Tale of Phantoms and Forgeries on the Disinformation Front Line (Oxford UP, 2026) reveals the rise and fall of the mavericks running Britain's Cold War forgery empire. Their secret mission was audacious: to disrupt and discredit adversaries across the world using phantom groups, fake sources, and counterfeit documents. The leader was a remarkable character, wrestling with personal and professional dilemmas: Hans Welser. An Austrian refugee and one-time MI5 suspect interned behind barbed wire, Welser was a great survivor who rose to become special operations adviser to the Foreign Office, working hand in glove with MI6. His second in command was an eccentric, hard drinking, and high-flying journalist-turned-propagandist called John Rayner. Brought out of semi-retirement, for one final posting. Their team of bowler-hatted refugees, voluble ex-journalists, trailblazing women, and licentious literary sorts navigated loyalty and betrayal — both professionally and romantically — from the diplomats' attic, in the most sensitive part of the Foreign Office's secret propaganda department. The newly declassified files expose an array of plots, some comically absurd and others dangerously controversial. The forgery empire impersonated everything from hippies and ghosts to Islamists and ballet composers in their campaign to smear hostile politicians, stir tensions among adversaries, and even stymie the career of a contentious British historian. All took place against a high stakes backdrop — both overseas as states competed beneath the looming threat of nuclear war and in the corridors of power at home where grey-suited bureaucrats circled, keen to shut down the team for good. With timely insight into how propaganda works and how to respond to disinformation, Fakers is a thrilling journey into a secret world where nothing was as it seemed.
