Felix dies in Saltburn because Oliver secretly poisons the alcohol Felix drinks in the hedge maze, causing what appears to be an overdose rather than an obvious murder.

Quick Scoop

What actually happens

  • After Felix discovers Oliver has been lying about his background, he pulls away from him and their friendship breaks down.
  • During a lavish party at the Saltburn estate, Felix follows or meets Oliver in the garden maze, where they argue but seem to part without violence.
  • Oliver has already spiked the bottle (champagne or liquor) he hands to Felix, lacing it with something lethal.
  • Felix drinks from the poisoned bottle in the maze, collapses there, and is found dead the next morning at the maze’s center.

How the film frames his death

  • To the outside world and the Catton family, Felix’s death looks like an overdose or tragic accident, not a clearly solved murder.
  • In the late-film reveal, Oliver’s narration and flashbacks show that he deliberately poisoned Felix, turning the “mystery” into a calculated killing that fits his larger plan to infiltrate and ultimately take over the Catton family’s wealth and estate.
  • Some explanations note that Oliver likely used a lethal amount of Farleigh’s cocaine in the bottle, letting him both kill Felix and make Farleigh look responsible for the drug-related death.

Why this matters to the story

  • Felix’s death is the turning point where Oliver’s obsession stops being “just” social climbing and becomes overtly homicidal.
  • It allows Oliver to stay at Saltburn while Farleigh is blamed and pushed out, clearing one more obstacle in Oliver’s path to controlling the family.
  • The way Felix dies—off-screen, seemingly unexplained at first, then recontextualized—feeds into the film’s themes of class envy, manipulation, and how easily a charming outsider can rewrite a wealthy family’s narrative.

In simple terms: Felix doesn’t drown or fall or die by random overdose; Oliver poisons his drink in the maze so that Felix’s death looks like a tragic, drug-related accident while actually being a planned murder.

TL;DR: In Saltburn , Felix dies after drinking from a bottle Oliver has secretly poisoned in the hedge maze, leading everyone to assume an overdose or accident when it is, in fact, murder.
