Peaky Blinders' Most Shocking Episode Is Why The Crime Thriller Is Still A Masterpiece 9 Years Later

A crime saga keeps changing
Set in early-20th-century Birmingham, Peaky Blinders follows Tommy Shelby, played by Cillian Murphy, as he builds the family gang into a powerful organization. Across six seasons and a movie, its reach grows into English politics, while new enemies test Tommy and take a toll on him.
The series combines stylized performances and anachronistic music with a story that continues to expand. Its pulp-fiction feel brings scheming rivals and narrow escapes, but major turns keep the drama from standing still.
A sudden loss reshapes expectations
In the season 4 premiere, a card bearing the Black Hand of the Sicilian-American Mafia signals fresh danger. The Americans arrive in Birmingham and shoot John and Arthur Shelby; John, played by Joe Cole, dies.
John was a central character, and his death came as a shock. Until then, the immediate Shelby family had seemed beyond the reach of the show’s most severe consequences. The killing made clear that this protection was gone.
The Mafia raises the stakes
Before the Mafia’s arrival, Tommy had faced a local gang leader, a corrupt detective, remnants of the IRA and exiled members of the Russian royal family. He had dealt with each without suffering a comparable loss.
John’s death established the Mafia as a formidable opponent. Later in the season, the audience can believe Arthur may also have been killed because the premiere has already shown what the group can do.
Risk keeps the story fresh
The article describes season three as the show’s weakest, with its pattern of introducing a villain who gains an advantage before Tommy defeats them. That repetition risked making the series feel procedural, with little changing from one season to the next.
Grace’s death in season three was another major turn, though it was less surprising because of her closeness to Tommy. Along with John’s death, it opened new story possibilities and showed the value of unexpected choices in a long-running series.
Key points
- John Shelby’s death in the season 4 premiere made the Shelby family’s vulnerability unmistakable.
- The Sicilian-American Mafia became a credible threat after killing John.
- The episode disrupted a pattern of villains being defeated with little lasting change.
- Grace’s and John’s deaths created new possibilities for the story.
