In the Netflix thriller His & Hers, the real killer is Anna’s mother, Alice.

Who is the killer in His & Hers?

  • The murders of Rachel, Helen, and Zoe are ultimately revealed to have been committed by Anna’s mother, Alice.
  • Throughout the series, Alice appears to suffer from dementia, which helps her avoid serious suspicion from the police and even from her own family.

How the finale twist plays out

  • For most of the story, suspicion shifts between Jack, Rachel’s husband Clyde, and Lexy/Catherine, making it seem like any of them could be the serial killer.
  • Near the end, it briefly appears that Lexy (who is actually Catherine Kelly) may be responsible, and she is even killed by detective Priya during a confrontation.

Why Alice kills

  • Alice discovers old video footage that reveals the truth about what Rachel, Helen, and Zoe did to Anna and Catherine when they were teenagers, including a horrific assault arranged in the woods.
  • After learning how the girls tormented Anna for years, Alice decides to exact revenge: she stabs Rachel in the woods on her car hood, slits Helen’s throat at the school where she once worked, and kills Zoe in her bathtub at home.

What this means for Anna and Jack

  • By the time the truth comes out, the authorities and even Anna initially believe Catherine/Lexy was the murderer, so Alice’s role is only revealed through a detailed confession note and flashbacks.
  • In her note, Alice explains that killing Rachel brought Anna home, killing Helen kept her there, and killing Zoe gave them back a kind of family, tying the emotional core of the twist to Anna and Jack’s shared grief.

Quick Scoop: “His and Hers who is the killer” (SEO-style wrap)
