Esther Finch (played by Jenn Lyon) is the main antagonist in the Netflix series Dead Boy Detectives (2024-). She’s one of the few who’s not dead in this series; in fact, she’s immortal. And she’s very good at holding a grudge. She is a witch who strikes a deal with Lilith to achieve immortality and even resorts to the darkest methods to make herself look young. In the Netflix series, Finch sets out on a vengeful path against the titular detectives and stops at nothing to ensure they learn the consequences of standing in her way.
