Paraplymordet - Historien om Agent Piccadilly

What Is the Series About?

Paraplymordet - Historien om Agent Piccadilly is a three-part Danish documentary series produced by DR and broadcast on DR1 and DRTV from 13 March 2023. It investigates the 1978 umbrella murder of Bulgarian dissident writer and broadcaster Georgi Markov on Waterloo Bridge in London — one of the most audacious political assassinations of the Cold War era — and connects that killing to what Danish broadcaster DR describes as Denmark's biggest espionage case. The series' central figure is Francesco Gullino, an Italian-born Danish citizen and antique dealer who allegedly operated as a spy for Bulgarian communist intelligence under the codename Piccadilly.

The title translates directly as The Umbrella Murder — The Story of Agent Piccadilly, and the series frames a question that has haunted intelligence services and true crime observers for more than four decades: was a man living quietly in Copenhagen the assassin who ended Markov's life with a poison pellet and an umbrella on a London bridge?

The Case

On 7 September 1978, Georgi Markov — a Bulgarian writer and journalist who had defected to the West and became a sharp, influential voice broadcasting for the BBC World Service and Radio Free Europe — was crossing Waterloo Bridge in London when he felt a sudden sting in the back of his right leg. A man behind him had jabbed him with the tip of an umbrella. Four days later, Markov was dead. A post-mortem examination revealed a tiny platinum pellet, no larger than a pinhead, embedded in his leg. The pellet had contained ricin, one of the most lethal poisons known.

The killing sent shockwaves through Western intelligence communities and became a defining symbol of Cold War-era state-sponsored assassination. Bulgaria's communist regime, under pressure from Moscow, was widely suspected of ordering the hit to silence one of its most effective and internationally prominent critics. For decades, however, no one was ever charged.

The documentary's key suspect is Francesco Gullino (1946–2021), an Italian-born man who became a Danish citizen and settled in Copenhagen, running a business as an antique dealer. According to reporting by Politiken and coverage by DR, Gullino was a former smuggler who was later recruited by Bulgarian state intelligence. He allegedly operated under the codename Piccadilly, carrying out intelligence work for the Bulgarian communist state.

In 1993 — fifteen years after the killing — English police traveled to Copenhagen and interviewed Gullino. According to DR, they left the interview convinced that the man they had questioned was a Bulgarian agent and the likely killer of Georgi Markov. Despite this, no formal charges were ever filed, no indictment was ever issued, and the case remained open and officially unsolved.

Berlingske's coverage of the documentary noted that much of the evidence points strongly toward Gullino's involvement, with the series presenting what Danish press described as "new heavy indicia" — substantial new material pointing at him as the perpetrator. Scotland Yard kept the case file open and at various points cooperated with foreign authorities as the investigation continued across decades.

Francesco Gullino died in 2021. He was never convicted of the murder of Georgi Markov. The Markov case therefore remains, in strict legal terms, unsolved.

Production

The series was produced by DR — Denmark's national public broadcaster — and aired on DR1 and its streaming platform DRTV. According to available sources, journalist and documentarian Ulrik Skotte was the driving force behind the project, conducting deep investigative work into the espionage case and its connection to the Markov assassination.

The production draws on decades of reporting and investigation, including access to material surrounding the 1993 police interview in Copenhagen and broader documentation of Gullino's alleged intelligence activities. A companion book, Paraplymordet, was also published by Gyldendal, further extending the investigative narrative for Danish audiences. The DRTV episode page lists the first episode as Spionen med de tusinde ansigter — "The Spy with a Thousand Faces" — a title that reflects how thoroughly Gullino concealed his alleged double life.

The series also reached international audiences via SVT Play in Sweden, reflecting the broader Scandinavian interest in the case and its Danish dimensions.

Reception

The documentary generated significant public and journalistic attention in Denmark upon its premiere on 13 March 2023. Danish press coverage described the series as presenting compelling new evidence, with Politiken noting the weight of the indicia pointing toward Gullino. The series is listed on IMDb under title ID tt28256835, though no verified audience rating score is available from current sources.

The central controversy the series provokes is stark: that a man who lived for years as a Danish citizen and antique dealer in Copenhagen was, in all likelihood, the Cold War assassin responsible for one of the most infamous targeted killings of the twentieth century. This allegation — explosive both in its geopolitical and domestic Danish implications — drove considerable viewer interest and press debate about how the case was handled and why no prosecution ever followed.

Criticism and discussion also centered on the broader systemic question: how does a suspected state-sponsored assassin live out his days in a Western European country, questioned by police but never charged, dying in 2021 without legal accountability?

The Case Today

With Francesco Gullino's death in 2021, any prospect of a criminal trial in the Markov case died with him. Scotland Yard had kept the investigation formally open for decades, and the 2023 documentary renewed public focus on what many investigators and journalists consider a solved case in all but legal name.

Georgi Markov's murder remains one of the most documented and discussed Cold War assassinations, a case that helped define the West's understanding of Bulgarian and Soviet intelligence methods during the Communist era. The documentary series ensures that the story — and the name of Francesco Gullino — is part of the permanent record, even as the courts never delivered a verdict.

For viewers outside Denmark, the series is available via Apple TV and has been broadcast on SVT Play in Sweden, bringing this Cold War cold case to an international true crime audience.
