[0957-2300] THE UMBRELLA DECLASSIFIED – Companion Dossier (PDF)

Description

At 1:45 p.m. on September 7, 1978, Bulgarian dissident Georgi Markov stood at a London bus stop on Waterloo Bridge when a sharp prick in his right thigh sealed his fate. Four days later, the BBC broadcaster was dead, baffling St Thomas’ Hospital physicians until an autopsy uncovered an engineered 1.52-millimeter platinum-iridium sphere drilled with microscopic ports. The forensic specialists at Porton Down soon identified the fatal cargo: ricin, an incurable cellular toxin deployed with surgical deniability. The Companion Dossier (PDF) chronologically documents this landmark Cold War assassination using declassified Bulgarian Secret Service surveillance logs, British inquest files, and KGB operational memorandums. Follow the precise paper trail from Markov’s defiant broadcasts at Bush House to the secret technical laboratories in Moscow that engineered compressed-gas umbrella delivery systems. Featuring forensic diagrams, declassified wiretap summaries, and ballistics data, this briefing reveals how a routine London commute transformed into one of the most calculated state-sponsored killings of the twentieth century.
