Margaret Drake: The Lost Sister at the Heart of All the Dangerous Things

Overview

Margaret Evelyn Rhett is Isabelle Drake’s younger sister, who died by drowning in a Beaufort marsh at age six. Her death, initially recorded as a tragic accident, is later revealed to be a murder committed by their mother Elizabeth during a postpartum psychotic episode. Margaret’s absence haunts the entire novel: Isabelle has repressed the memory for decades, the family has sealed the truth behind a lie, and the weight of that buried secret shapes Isabelle’s guilt, her sleepwalking, and her desperate search for her own son Mason. Though Margaret appears only in flashbacks, she functions as the novel’s central ghost — the innocent victim whose loss exposes the fractures in the Rhett family and the destructive power of silence.

Plot Role

Margaret’s drowning is the mystery that the novel’s final act solves. For most of the story, Isabelle believes she may have killed her sister while sleepwalking. This suspicion drives her lifelong insomnia, her obsession with Mason’s disappearance, and her compulsive need to uncover the truth. The reader learns about Margaret through fragments: a hidden painting of a girl standing in the marsh, a lullaby sung to a doll, and whispered conversations that were never meant to be remembered. When Isabelle’s mother finally confesses in Chapter Forty-Nine, Margaret’s death is re‑framed as an act of psychosis rather than an accident — and Isabelle’s guilt is lifted. Margaret’s plot role is therefore twofold: she is both the catalyst for Isabelle’s psychological wounds and the key that unlocks the family’s decades‑old cover‑up.

Motivations and Traits Shown Through Actions

Margaret is portrayed as a trusting, observant, and deeply loyal child. She is small for her age (she places both feet on each stair as she descends) and relies heavily on Isabelle for comfort and guidance. When she notices muddy footprints from Isabelle’s bed, she asks directly, “Is it because of what happened?” — revealing a child who is perceptive about the family’s unspoken trauma. She also names her baby doll “Ellie” after the sister Eloise who died shortly after birth, an act that unintentionally torments their grieving mother. Yet Margaret does not seem malicious; she is simply repeating the names she has overheard. Her most defining trait is her trust in Isabelle. When Isabelle promises “I won’t hurt you,” Margaret nods and believes her — a promise that proves tragically hollow. In the final moments of her life, Margaret likely followed Isabelle into the marsh, not out of curiosity but out of a desire to protect or accompany her big sister.

Chronological Arc

Margaret’s arc is told entirely through memory and revelation. The timeline, pieced together from evidence:

  • April 27, 1999 — Eloise Annabelle Rhett is stillborn. Margaret is three years old. The parents never explain the loss to their children, and the baby’s nursery door is simply closed.
  • Summer 1999 — Isabelle begins sleepwalking, likely triggered by the trauma in the house. Margaret notices the muddy footprints and asks about “what happened,” but Isabelle tells her they aren’t supposed to talk about it.
  • July 17, 1999 — Margaret dies. Her mother, in a dissociative state, leads both girls into the marsh, drowns Margaret, and attempts to drown Isabelle. Their father arrives in time to stop the second drowning but not the first. He and Chief Montgomery stage the death as an accident.
  • Six months after death — Isabelle recalls the funeral, where Margaret is buried with her doll Ellie. The family retreats into silence. Isabelle starts having recurring dreams of standing at the water’s edge with her sister.
  • Present day of the novel (2022–2023) — Isabelle still dreams of Margaret and remains convinced she was responsible. Only during the climactic confession does she learn the truth, freeing her from a guilt she has carried for twenty‑four years.

Relationships

With Isabelle: Margaret idolised her older sister. She followed Isabelle everywhere, slept in her room, and listened to her instructions. Isabelle, in turn, was fiercely protective — she made her breakfast, guided her down stairs, and promised to keep her safe. That protective instinct later curdles into unbearable guilt when Isabelle suspects she harmed Margaret during a sleepwalking episode. The truth — that their mother was the aggressor — does not erase the love, but it does sever the false blame.

With Elizabeth (mother): Margaret is innocent of the pain her presence causes. She unknowingly triggers Elizabeth’s grief by naming her doll Ellie (a phonetic echo of “Eloise”). Elizabeth’s psychosis turns that innocence into a target. In Chapter Fifty, Isabelle realises her mother “didn’t do it on purpose” — the illness, not the woman, killed Margaret. Yet the relationship is defined by betrayal: a mother who should have protected her child instead ended her life.

With the father (Charles): Charles Rhett is absent during the murder and complicit in the cover‑up. Margaret’s death exposes his prioritisation of reputation over truth. He does not seek justice for his daughter; he protects his political name and his wife from prosecution. Margaret, from the grave, becomes a symbol of his moral failure.

With Eloise: Margaret never knew her stillborn sister, yet she honours her by naming her doll. This act of innocent remembrance precipitates the final break in Elizabeth’s sanity. Margaret’s life and death are thus linked to Eloise’s: two daughters lost to the same maternal illness.

Key Decisions and Consequences

The most consequential decision in Margaret’s story is made not by her but about her: her father’s choice to stage her death as an accident. This cover‑up allows the family to present a unified front, but it condemns Isabelle to decades of self‑blame. Margaret’s own choices are limited by her age, but her decision to follow Isabelle into the marsh — out of trust, not fear — leads directly to her death. In a deeper sense, Margaret’s decision to speak about the forbidden topics (the footprints, “what happened,” the name Ellie) shows a child trying to make sense of a house full of secrets. The consequence of that openness is that it exposes the cracks in the family’s silence, eventually forcing the truth to the surface.

Theme and Symbol Connections

Margaret embodies several of the novel’s core themes, explored in detail on the themes pages. She is the innocent victim whose death is hidden — a direct result of family secrets and cover‑ups. Her murder by her own mother illustrates the theme of inherited mental illness and societal pressure on motherhood, as Elizabeth’s postpartum psychosis is ignored and hidden. Margaret also symbolises guilt and unreliable memory: Isabelle’s false memory of harming her sister is the novel’s primary red herring, and only by confronting the past can Isabelle break free. Finally, Margaret’s death is intimately tied to sleep deprivation and trauma: Isabelle’s sleepwalking began after Eloise’s stillbirth, and her lifelong insomnia is a direct consequence of the repressed memory of that night. The marsh itself becomes a symbol of death and hidden truth — the place where Margaret drowned and where Isabelle’s own son Mason was later taken.

Frequently Asked Questions About Margaret Drake

1. How did Margaret Drake die?

Margaret drowned in the marsh behind the Rhett family home. For most of the novel, the death is presented as a childhood accident. In Chapter Fifty, Isabelle learns the truth: her mother Elizabeth, in the grip of postpartum psychosis, led Margaret and Isabelle into the water, held Margaret under, and tried to drown Isabelle. Their father arrived too late to save Margaret but stopped the attack on Isabelle.

2. Why did Isabelle think she killed Margaret?

Isabelle suffered from sleepwalking as a child. She often woke up in strange places with no memory of how she got there. On the night Margaret died, Isabelle had a fragmented image of standing in the marsh with her sister. She assumed she must have led Margaret there while asleep and accidentally hurt her. This false memory was reinforced by her parents’ silence and by her father coaching her on what to say to the police.

3. Was Margaret’s death an accident?

No. It was a homicide committed by Elizabeth Rhett, though she was not criminally responsible due to her mental state. The death was covered up as a drowning accident by Charles Rhett and Chief Montgomery to protect the family’s reputation.

4. What is the significance of Margaret’s doll Ellie?

Margaret named her baby doll “Ellie” after her stillborn sister Eloise. The name unintentionally reminded Elizabeth of her lost child and deepened her grief and psychosis. The doll was buried with Margaret in her casket, symbolising the mother’s inability to let go of either daughter. Isabelle later reflects on the eeriness of the doll’s open eyes being buried in darkness forever.

5. How does Margaret’s death affect the novel’s ending?

The revelation of Margaret’s true cause of death frees Isabelle from a lifetime of guilt. It also exposes the depth of the family’s cover‑up and allows Isabelle to finally confront her parents. In the epilogue, Isabelle visits Margaret’s grave and acknowledges that her mother lived with self‑hatred, not hatred for Isabelle. This closure helps Isabelle move forward and accept her son Mason’s return.
