The killer in the Netflix thriller series His & Hers is Alice Andrews , Anna’s mother.

Quick Scoop

  • For most of the show, suspicion shifts between Jack, Anna, and Lexy/Catherine, making it seem like one of them must be the murderer.
  • In the finale’s final stretch, a letter reveals that Alice has been secretly responsible for the murders of Rachel, Helen, and Zoe.
  • Alice fakes dementia and uses her perceived frailty to avoid suspicion while carrying out the killings.

How the Twist Works

  • After Anna vanished following her baby Charlotte’s death, Alice obsessively watched Anna’s old camcorder tapes and discovered the truth about the assault on Catherine (later Lexy) and Anna’s role in that night.
  • Consumed by rage and twisted protectiveness, Alice decides to “correct” the past by murdering the women from Anna’s old friend group: first Rachel in the woods, then Helen at the school, and finally Zoe in her bathroom.

Why Everyone Thought Lexy Did It

  • Lexy is revealed to be Catherine Kelly, the bullied girl from Anna’s past, giving her a clear revenge motive against Rachel, Helen, Zoe, and Anna.
  • Evidence is planted to point to Lexy, and she even pulls a gun on Anna before being shot by Priya, which makes the case look closed and convinces the town she was the killer.

Alice’s Motive In A Nutshell

  • Alice’s murders are driven by a mix of grief over her granddaughter’s death, anger at what Anna’s friends did years ago, and a warped desire to “bring Anna home” and rebuild a family.
  • In her letter, she spells out that killing Rachel brought Anna back, killing Helen kept her there, and killing Zoe gave Anna the family she lost, completing her chilling logic.

Bottom line: The real killer in His & Hers is Anna’s mother, Alice Andrews, not Lexy, Jack, or Anna.
