It happened. Finally. After months of coffee, cherry pie, and cryptic dreams about giants and dwarves, David Lynch and Mark Frost finally gave us the answer. Twin Peaks Season 2 Episode 9, titled "Arbitrary Law," is the moment the floor dropped out from under the audience. It’s the episode where we find out who killed Laura Palmer.
Honestly, it’s a miracle this episode even exists in the form it does.
Think back to 1990. Television didn't do this. TV was meant to be episodic, safe, and eternal. You weren't supposed to solve the central mystery because the mystery was the engine that kept the show running. But the network—ABC—was screaming. They wanted blood. They wanted a name. So, Lynch and Frost gave them Leland Palmer. But they did it in a way that felt less like a resolution and more like a funeral for the show itself.
The Brutal Reality of Leland Palmer
The revelation in Twin Peaks Season 2 Episode 9 is devastating because it isn't a "whodunnit" victory. It’s a tragedy. When Special Agent Dale Cooper finally puts the pieces together—realizing that the "giant" was right all along—the atmosphere in the Sheriff’s Department shifts from procedural tension to pure, unadulterated horror.
Ray Wise, the actor playing Leland, delivers what might be the most physical, soul-crushing performance in the history of the medium.
He’s possessed. He’s Bob. He’s a father who has done the unthinkable.
The scene in the interrogation cell is hard to watch. It's supposed to be. When Leland (or rather, the entity inhabiting him) starts slamming his head against the door while singing "Mairzy Doats," it isn't just "weird" for the sake of being weird. It is the manifestation of a family’s trauma exploding in a sterile room. Most shows would have ended with a pair of handcuffs and a sigh of relief. This episode ends with a man dying in Cooper's arms while the sprinklers wash away the sins of a town that was never really innocent to begin with.

The Lodge, The Giant, and the Gum
Remember the gum? "That gum you like is going to come back in style."
It’s such a throwaway line in the pilot. But in this episode, it becomes the key. When the elderly room service waiter at the Great Northern tells Leland that his favorite gum is back, it’s the cosmic signal that the end is here. This is classic Lynchian storytelling—using the mundane to signal the metaphysical.
The Giant appears to Cooper in the Roadhouse. He returns the ring. The message is clear: the mission is over, but the cost is absolute.
A lot of fans argue that Twin Peaks Season 2 Episode 9 is the true "finale" of the original run. While the show famously spiraled into some pretty questionable subplots afterward (looking at you, James and Evelyn), this specific hour of television remains a masterclass in atmosphere. It manages to balance the supernatural elements of the Black Lodge with the grounded, gut-wrenching reality of child abuse and domestic rot.
Why This Episode Was a Suicide Mission for the Show
Here is the truth: solving the murder killed the ratings.
David Lynch never wanted to reveal the killer. He famously compared the mystery of Laura Palmer to a "goose that laid golden eggs." Once you kill the goose to see what's inside, the magic stops. ABC didn't care about the magic; they cared about the numbers. They thought that by giving the audience the answer in Twin Peaks Season 2 Episode 9, they would satisfy the viewers and move on to the next mystery.
They were wrong.
The audience didn't just want to know who killed Laura; they wanted to live in the mystery. Once Leland died and Bob escaped into the woods, the tension evaporated. The show lost its North Star. If you watch the episodes immediately following this one, you can feel the writers scrambling. They try to pivot to Windom Earle, but without the ghost of Laura Palmer hanging over every pine tree, it just felt like a different show.
Breaking Down the Cooper-Leland Dynamic
The chemistry between Kyle MacLachlan and Ray Wise in this episode is electric. Cooper isn't just a detective here; he’s a witness.
When Cooper recites the Tibetan Buddhist prayers as Leland lies dying, it’s one of the few times we see the "Sherlock Holmes" veneer of the character crack. He’s genuinely moved. He’s heartbroken for this man who was a vessel for a literal demon.
- The Sprinklers: Symbolizing a baptism, a cleansing of the Palmer bloodline.
- The Poetry: Cooper’s use of spiritual texts anchors the show's weirdness in a sense of genuine empathy.
- The Mirror: The recurring theme of doubles—Leland and Bob—reaching its inevitable, shattered conclusion.
It’s heavy stuff. It’s also incredibly sophisticated for a network drama airing on a Thursday night in the early 90s.
The Legacy of Arbitrary Law
You can't talk about modern "prestige TV" without acknowledging what happened in this episode. Shows like True Detective, Lost, or The Killing all owe their DNA to the way Twin Peaks Season 2 Episode 9 handled its big reveal. It proved that you could have a "villain" that was both a human being and a primordial force of evil.
However, it also serves as a warning.

It warns creators about the dangers of "mystery boxes." If you build a show entirely around one question, you better be prepared for what happens once you answer it. Lynch and Frost weren't prepared—at least not for the fallout. The show was canceled shortly after, only to be resurrected decades later in The Return, where we learned that the darkness in Twin Peaks was much, much deeper than a single murder in a small town.
Fact-Checking the "Lynch wasn't involved" Myth
There’s a common misconception that David Lynch had checked out by this point. That’s not entirely true. While he was frustrated by the network’s demands, he directed the reveal episode (Episode 7) and was heavily involved in the creative direction of Episode 9. He knew that if they were going to do it, they had to do it with maximum impact.
He didn't want a tidy ending. He wanted a scar.
And that’s exactly what "Arbitrary Law" is. It’s a scar on the face of American television. It’s the moment we realized that the "good guys" don't always win, even when they catch the killer. The killer might be dead, but the evil—the Bob—is still out there, lurking in the Douglas firs, waiting for a new host.
How to Revisit Episode 9 Today
If you're going back to watch Twin Peaks Season 2 Episode 9 now, you have to look past the 90s film grain and the occasionally soap-opera lighting. Focus on the sound design. The low-frequency hums. The way the wind seems to howl inside the buildings.
This isn't just a TV episode. It’s a sensory experience.
Pay attention to the background characters, too. Look at Deputy Andy and Sheriff Truman. Their reactions to Leland’s confession aren't just "actor" reactions; they feel like the reactions of people whose entire world has just been tilted off its axis. They live in a town where people leave their doors unlocked. After this episode, they never will again.
Actionable Insights for the Ultimate Rewatch
To truly appreciate the craftsmanship of this era, follow these steps during your next viewing:
- Watch for the hands: In Lynch’s world, hands are everything. Notice how Leland’s hands move compared to Bob’s. The "shaking" is a direct link to the nervous system of the town itself.
- Listen to the silence: This episode uses silence more effectively than most modern horror movies use jump scares. The quiet moments in the interrogation room are where the real dread lives.
- Contextualize the "The Return": If you haven't seen the 2017 revival, watch Episode 9 and then jump straight to the finale of Season 3. The parallels in how Cooper handles "closure" are staggering and will change how you view his character's "heroism."
- Track the "Bob" sightings: He isn't just in the mirror. He’s in the shadows of the room, often just out of focus. It reinforces the idea that evil isn't an intruder; it's a neighbor.
The "mystery" may have been solved in the woods that night, but the questions it raised about the nature of evil, trauma, and the American dream are still being debated by fans thirty years later. That is the mark of an episode that didn't just follow the rules—it rewrote them.
