The real murderer in His & Hers is Anna’s mother, Alice Andrews (often just called Mrs. Andrews).

Who the killer is

  • The story initially makes it look like several people could be the killer, especially Lexy/Catherine and even Anna or Jack.
  • By the end, it is revealed that Alice Andrews is the one who killed Rachel, Helen, and Zoe in Dahlonega.

How the twist is revealed

  • The case seems “solved” when Lexy (Catherine Kelly) is blamed and then killed, so everyone believes she was the serial killer.
  • About a year later, Anna finds a confessional letter/notes from her mother, where Alice admits she committed all three murders.

Why Alice kills them

  • As a teenager, Anna was lured into the woods by Rachel, Helen, and Zoe, who planned for Anna and Catherine to be sexually assaulted; Anna was attacked, Catherine escaped.
  • Alice later discovers what happened to her daughter and decides to take revenge on the women she believes destroyed Anna’s life.
  • She also frames Lexy/Catherine by planting evidence and even fakes dementia so no one suspects her while she uses old house keys from her cleaning jobs to access victims’ homes.

Was Lexy/Catherine the murderer?

  • Lexy/Catherine is heavily framed as the killer, and the police officially close the case with her as the culprit.
  • The final reveal clarifies that she did not kill Rachel, Helen, or Zoe; she had her own dark past (her sister’s death), but the Dahlonega murders were all Alice’s doing.
