Harlan Coben's Lazarus Episode 06 Recap: Joel Finds Sutton's Killer

By Mira Vance · Editor & Lead Reviewer

Harlan Coben’s Lazarus, Season 1, Episode 06 Prime Video · 2025

Joel gets the answer he has wanted for Sutton, then finds out grief does not finish on command.

Joel Lazarus (Sam Claflin) enters Episode 06 with one murder case nearly in reach and another question waiting underneath it. He is drunk, furious, and ready to drive to the hospital because Sam Olsen has handled Sutton’s toy dog. Jenna Lazarus (Alexandra Roach) stops him before he can ruin the one good piece of evidence they have, DCI Alison Brown (Kate Ashfield) finally moves on Olsen, and Aidan’s disappearance drags Bella’s family into the centre of the old wound.

By the close, Sutton’s death has an answer. Joel still does not have peace.

Jenna stops Joel from confronting Olsen

Joel is almost out of control when Jenna finds him in the car. He has the toy dog, the one visible in Sutton’s bedroom on the night she died, and he knows Olsen had it in his house. He wants to go straight to Olsen’s hospital bed, put the evidence in front of him, and tell him he knows what happened.

Jenna understands the danger before Joel does. If he shows Olsen the dog before the police have him, he only gives him a warning. She gets him to Seth McGovern (David Fynn) at half three in the morning, where Joel promises “no ghouls, no ghosts” and lays out the physical evidence instead.

That promise matters. Joel has spent the season asking people to believe things they cannot verify. Here, for once, he has something solid: a VHS image, a toy, and the man who should never have had it.

Brown’s response is careful enough to infuriate him. She calls the evidence compelling but not conclusive. Olsen can deny the dog came from his house. His legal team can suggest Sutton had two similar toys. Joel hears delay. Brown hears a case that has to survive court.

The warrant finally comes through, but the delay costs them. Armed police search Olsen’s home and find no Olsen. Joel’s anger is immediate: doing it properly has given Olsen time to run.

Then the search finds something worse than absence. Behind framed pictures are clothes and girls’ underwear. Brown orders them bagged and tells the team to check the other pictures. The toy dog has opened a door, but what sits behind it is older and uglier than Joel’s first theory.

Joel and Jonathan argue over Sutton’s death

Before the chase tightens, Joel is pulled back into the room where his own damage began. In Jonathan Lazarus’s office, the ghost of Dr Jonathan Lazarus (Bill Nighy) brings Joel into the memory of his younger self asking for reassurance after Sutton’s murder.

Young Joel says he saw Sutton leave the dance upset and stayed behind. He wants to be told that her death is not his fault. Jonathan gives him an answer that may be intellectually honest and emotionally brutal. He says the only person who can forgive Joel is Joel, because only Joel can account for the choices now troubling him.

That is not what a grieving son needs to hear.

Adult Joel finally says the thing he has carried for years. Jonathan did not rescue him. He watched a boy who could not swim drown in guilt. Joel believed the person who mattered most to him held him responsible for Sutton’s death.

Jonathan denies blaming him, but he does not excuse himself. He says Sutton’s death opened a void, and he admits he failed Joel and Jenna, especially Joel. He was as hard on Joel as he was on himself, then sent a young man down that road alone.

The apology is not soft. Joel does not become well because his father can now explain the mistake. When Jonathan says he always wanted to think Joel came through okay, Joel answers with the line he has been avoiding: “But I’m not okay.”

That line lands because Jonathan’s ghost is not a shortcut. Jonathan can appear. Jonathan can speak. Jonathan can confess his failure. None of that returns Joel’s twenties, or Sutton, or the version of family that died with her.

Aidan goes missing after the paternity test

Bella arrives looking for Aidan, and Joel is forced to tell her what happened the night before. Aidan came to him with a paternity test. He had taken Joel’s toothbrush, sent off the sample, and received the result: Joel is his biological father, not Paul.

Bella’s first response is shock, then protection. She insists Aidan is Paul’s because Paul brought him up. Joel says he is not trying to supplant anyone, but the word itself sounds too formal for the room. Bella has a missing son, a shaken marriage, and a man from her past suddenly standing inside both.

Seth interrupts with CCTV. Olsen’s car was seen heading north out of the city late the previous night, and someone is in the passenger seat. The image is poor, but Joel recognises the jacket. It is the one Aidan wore.

Bella’s fear turns on Joel because Joel has become part of the reason Aidan ran. He tries to say he will help Paul look for him. Bella cuts him off. Aidan is her everything, and Joel is not to start claiming him now.

Joel finds the trail through a detail from earlier: Sam Olsen had talked about going fishing for Arctic char. By the water, Aidan is with Olsen, and for a few seconds the scene is almost horribly ordinary. Aidan asks how to kill a fish. Olsen tells him they do not kill what they cannot eat.

Then Joel arrives, tells Aidan to go to the car, and shows Olsen the image from Sutton’s room. The proof sits there in the top left corner, on the manikin. Olsen tells Aidan to leave. Aidan refuses. Joel pushes.

Olsen breaks.

He says he loved Sutton, protected her, tended her grave, and had to lead Joel there so Joel could see what he had done for her. The words are not remorse. They are ownership. When Joel forces him to explain the night Sutton died, Olsen says the family used to leave a key under a stone and that he had gone in and out of the house for years.

He was in Sutton’s room to take the dog. Sutton came home early from the ball. Olsen claims she threw herself at him, that he kissed her “with all the love in the world,” and then, when Joel and Jonathan came home, he killed her. Even his confession tries to put the act back on Sutton. “She made me do it.”

Joel attacks him, and the fight turns dangerous fast. Aidan intervenes. Brown arrives. Olsen is alive, Joel is alive, and the case against Sutton’s killer is no longer guesswork.

Olsen’s arrest does not close Jonathan’s death

Brown confirms what Joel has been saying about Sutton. They found photos in Olsen’s house dating back to the time she was killed, photos of Sutton’s room and her things. When Joel asks whether she is with him now, Brown says yes.

For Joel, that should be the release. It is not. Brown asks what he would have done if they had not arrived when they did, and there is no clean answer. Joel wanted justice. He also wanted to hurt the man who turned his sister’s death into a private shrine.

The aftermath is quieter and more honest. Brown tells Joel that Jonathan would want her to be there for him. She says Jonathan rated him and admits she misses him. Bella, still shaken, tells Joel that Aidan is not talking, then asks whether Joel sees any of himself in him. Jonathan had seen Aidan for a few sessions, but Aidan had not wanted to continue.

At the pub, Jenna names the strange emptiness after the arrest. Aidan is safe and Olsen is caught, but there is no closure because nothing brings Sutton back. Maybe, she says, this is the point where people like them can start grieving.

Joel tries to move forward in his own ungainly way. He rings Laura late, crosses the therapy boundary, apologises when she calls it inappropriate, and then finds a way to ask her for a drink after she makes clear she is no longer his therapist.

For a moment, Joel chooses life.

Then Brown brings the news that cuts through the whole case. Olsen was 200 miles away on the day Jonathan died. The alibi is documented and solid. Brown has searched his house top to bottom, and there is nothing tying him to Jonathan.

Seth says the thing Joel cannot accept: Olsen did not kill Jonathan. No one did. Jonathan took his own life.

Joel returns to the office and begs for guidance. Jonathan does not come. Arlo Jones does. The dangerous patient from the opening chapter attacks Joel, calls him “the great betrayer of confidences,” and quotes scripture while claiming God has asked him to punish Joel. Joel survives the attack, but Arlo’s final shout follows him: “And it’s not over.”

The last clue is not Olsen. It is Jonathan’s note. Joel remembers that the page he had read sounded like the end of a sentence, not the beginning. If there was a page one, then Jonathan’s death may still depend on something Joel has not found.

What works

• Joel and Jonathan’s office confrontation carries the emotional weight. Jonathan’s apology is late, imperfect, and still necessary.
• Sutton’s case resolves through tangible evidence: the toy dog, the bedroom image, the hidden photos, and Olsen’s own explanation of how he entered the Lazarus house.
• Bella’s anger keeps Aidan’s paternity reveal from becoming a neat surprise. Joel may be Aidan’s biological father, but Bella is right to defend the life Paul actually built with him.
• Brown is useful because she pushes back on Joel without dismissing him. Her process frustrates him, then protects the case once Olsen is caught.

What stumbles

• Olsen’s confession carries the right ugliness, but the timing is very convenient: the killer, the missing boy, the fishing clue, and the final confrontation all line up quickly.
• The Laura phone call is lighter than the surrounding material, and the ethical boundary shift feels rushed after so much grief and violence.
• Arlo’s return is a sharp jolt, but it arrives so late that it feels like a hook being forced into the closing minutes.

What this sets up for Episode 07

There is no Episode 07, which makes the last turn deliberately sour. Sutton’s killer is found, but Jonathan’s death is pushed back into doubt by Olsen’s alibi, Arlo’s attack, and the possibility of a missing first page. Joel is left with the beginning of grief, not the end of the case.
