In this piece

Eddie Horniman is the second son who inherited a dukedom he was never meant to have, discovered a cannabis farm under his lawn, spent a season trying to get out of it and a season trying to expand it, and ended season two forcing his own brother to behead a man with a chainsaw. He is played by Theo James.

Full spoilers for both seasons below.

Who is Eddie Horniman?

A former British Army captain who served as a UN peacekeeper, and the younger of the late Duke's two sons. When Archibald Horniman, the 12th Duke of Halstead, dies in the first episode, the title and the estate pass to Eddie rather than to his older brother Freddy (Daniel Ings).

Freddy is the only one who reacts with fury, but Eddie is surprised too. He had spent his life treating Freddy as the heir and himself as the spare; the Army was the life he built outside the inheritance. What distinguishes him is not that he expected the title — it is that he is the only functioning adult in the house. His mother is elegant and unbothered, his brother is a cocaine addict, his sister is away at university. The show's opening joke is that the least entitled member of the family is the one who can actually run an estate.

He is also, crucially, calm around violence in a way the series keeps quietly explaining through his service record. That calm is the thing everything else grows out of.

Season one: the inheritance and what came with it

Eddie finds out after the funeral that his father had a long-standing arrangement with the Glass family. Underneath the Halstead grounds is an industrial cannabis operation belonging to Bobby Glass (Ray Winstone), who is in prison, and run day to day by his daughter Susie (Kaya Scodelario).

He wants out immediately. The arrangement predates him and the Glasses will not simply be evicted, and then Freddy makes the situation immeasurably worse.

Freddy owes a fortune to Tommy Dixon (Peter Serafinowicz), Susie negotiates the debt down to £4 million with a humiliating chicken-suit performance attached, and Freddy shoots Tommy dead on camera at the end of the first episode. That murder turns an inherited problem into a personal criminal conspiracy Eddie now has to conceal.

His solution tells you who he already is. Rather than let Susie kill the only outside witness, Eddie frames Tommy's accountant Jethro (Josh Finan) for the killing, pays him £2 million and puts him on a boat to Australia — then sells that version to Tommy's brother Gospel John (Pearce Quigley). It works. What Eddie does not know is that Susie has already arranged for Jethro not to survive the voyage.

That is the first serious crack between them, and it establishes the pattern. Eddie solves problems by constructing something plausible and selling it to the person who most needs to believe it.

The moment he changes

The whole first season is Eddie being pulled in while insisting he is on his way out — and being far better at it than a man leaving ought to be.

It ends with Bobby announcing a fake sale of the business, which turns out to be a test of both Eddie and his own daughter. They pass it by manipulating every other bidder off the board.

Then the scene that decides the character. Henry Collins (Max Beesley), the man who nearly killed Susie's brother, is taken to the woods. Eddie offers Susie the gun. She tells him the kill belongs to his own journey, and he shoots Collins himself. They end the season not as landlords collecting Bobby's rent, but as co-owners of the Glass business alongside him and Susie.

Season two: ambition

A year later, Eddie is not reluctant about anything.

His plan is to get marijuana decriminalised, invest in the legal trade, and quietly feed illegal Glass product into the legitimate market. To get the votes he wants a seat in the House of Lords, which he obtains through Lord Hawthorne (Hugh Bonneville) — and then secures Hawthorne's compliance by drugging him and staging a corpse in his bed so he wakes believing he is a murderer.

That is the same trick he played on Gospel John, run on a peer of the realm. The man who spent season one trying to leave spends season two trying to expand, and the methods have not changed at all. Only the scale has.

Stanley Johnston (Giancarlo Esposito) spends the season encouraging it, in cathedrals, at length, in the vocabulary of lineage and destiny.

The fall

Bobby wants the bill dead to protect what he already has. When Eddie moves against him, Bobby has Hawthorne killed, staged as a heart attack and a fall from a window. The warning takes the peer and the bill together. Then he has Eddie beaten and left in a shallow grave with two broken legs and a broken arm.

He crawls out and follows a line of painted X's to a road. That image — a wrecked man dragging himself through a field — is what the season opens on, three months before it happens.

To repay Marco Moretti (Sergio Castellitto) he borrows £100 million from Stanley Johnston, with Halstead as security.

Then he marries Bella (Benedetta Porcaroli), the contessa who took Cico Maldini's place in the Italian operation after Moretti had him killed. It begins as an alliance between two families and does not stay one — Netflix's own account is that Eddie falls in love with her. Her seaplane explodes in front of him within hours of the ceremony at Lake Maggiore.

The revenge

Eddie tortures a captured mercenary until the man names Bobby, and commissions Moretti to have him killed in prison.

He has the wrong target. Susie brings him what he is missing — Bobby bought Eddie's debt from Johnston on the morning of the wedding, which makes him the last man who wants Eddie dead — and Johnston confirms it by phone. Eddie reaches the prison in time to help, though Bobby finishes the assassin himself.

His parting line is that holding the debt does not mean owning him.

Then his mother mentions that Freddy rang home after a bad dream, and Eddie remembers telling his brother exactly how Bella would be travelling. Using Susie's relationship with Carlos Vargas (Cosimo Fusco), the two of them lure Gospel John into a bonded warehouse, wipe out his protection, and leave him alive on purpose.

He confronts Freddy, beats him, pulls a gun and does not fire it. A van opens: Gospel John bound inside, next to a man with a chainsaw. Eddie tells his brother somebody has to die and puts him in the van. Freddy comes out holding the head, and Eddie lights a cigar.

What the makers say he is becoming

Theo James, who is also a co-executive producer on the show, has cited *The Godfather Part II* as the model — a man who gets better and better at destroying his enemies while losing pieces of himself. He describes the finale as Eddie psychologically castrating his brother while taking revenge on the man who killed his wife.

Matthew Read frames the ending as a deliberately open question: has Eddie gone mad, or is he becoming a ruthless leader capable of extraordinary things? Read leans towards the second.

Where season two leaves him

A peer of the realm. A widower. A man who has taken an already murderous brother and made him kill again, this time deliberately and on command.

And Halstead is more exposed than when he started. The estate secured Johnston's £100 million loan, and Johnston sold that debt to Bobby. Eddie's defiant closing line does not change who holds the security.

Our reading: Eddie's problem across two seasons has never been capability. He is obviously capable. It is that the power he acquires keeps arriving tied to somebody else's leverage — the dukedom came with the Glasses attached, the peerage came through Hawthorne, and the money that cleared Moretti ended up in Bobby's hands. Too many of his threats have had a creditor standing behind them.

On that reading, a third season that finally gives him something he owns outright is the one where he becomes genuinely dangerous. Season three is confirmed for eight episodes with Ritchie directing, and nothing about the story has been announced.
