Isabelle Lockett Forsythe

Isabelle Lockett Forsythe is Lavinia Lockett’s elder sister, closest confidante, and first interpreter of the strange life Lavinia claims to have shared with Theodore Sewall. Her decisive significance lies in the tension she sustains between ordinary domestic reality and supernatural possibility: she cares for a child, supports a grieving sister, and inhabits the routines of family life, yet she also becomes the person who hears Lavinia’s impossible testimony and quietly preserves a desire to believe it.

Identity and Family Background

Isabelle is presented as deeply bonded to Lavinia. After their parents died of consumption, Isabelle remained practically inseparable from her sister even after marrying Lyle Forsythe, a manager at the quarry. The sisters’ closeness is therefore not a sentimental embellishment but a durable household structure: Lavinia worked as a seamstress to help pay the bills, while Isabelle built a marriage and family without abandoning her original attachment.

Isabelle is also a mother to Betsy. Her care for the child repeatedly interrupts and organizes the adult conversations around her. When Theodore Sewall visits, Betsy sits comfortably on Isabelle’s hip; when Betsy begins crying after bumping her finger, Isabelle immediately turns to the child’s nap and asks to be excused. Her maternal responsibility gives the scenes a practical counterweight to the charged attraction between Lavinia and Theodore, grounding the household in bodily needs, schedules, and care.

Sisterhood and Domestic Care

Isabelle acts as Lavinia’s social and emotional intermediary. She announces Theodore’s arrival from the doorway of Lavinia’s tiny bedroom, urges her sister downstairs, and then deliberately leaves the pair together after Theodore asks whether he may call again. The gesture shows both her impatience and her confidence in Lavinia’s feelings: Isabelle recognizes the importance of the visit before Lavinia can comfortably name it herself.

Her care becomes more solemn after Theodore disappears aboard the Sweet Lavvy. On the couple’s wedding anniversary, Isabelle and her family visit Lavinia to deliver the news that the ship’s stern has washed ashore in Boston, confirming that the vessel is gone. Lyle sits in a straight-backed chair, Betsy plays quietly with a doll, and Isabelle sits beside Lavinia in the chilly parlor beneath a single oil lamp. She takes Lavinia’s cold hand, notices that her sister has barely spoken, and urges her to talk because she believes conversation might help. Yet Lavinia remains blank-faced and unable to accept that Theodore is dead, leaving Isabelle to confront grief that cannot be reached through ordinary consolation.

Isabelle’s practical tenderness also appears in the spring visit to the quarry. She leaves Betsy with Lavinia and makes the vigorous walk to see Lyle, carrying scones baked by Lavinia and a small jar of clotted cream. At the quarry she watches Lyle laughing with the workers and takes pleasure in his amiability and the respect he commands. The scene places her within a network of reciprocal domestic and marital affection: Lavinia’s labor feeds Isabelle’s gesture toward Lyle, while Isabelle’s household remains connected to both her sister and her husband.

The Impossible Revelation

When Lavinia finally tells Isabelle that Theodore is present, Isabelle’s first response is disbelief. Lavinia asks what would happen if Theodore were there, and Isabelle’s mind turns quickly enough to understand the claim; tears spring to her eyes as she shakes her head. Lavinia places a hand on her sister’s knee and insists that she is telling the truth, asking Isabelle to hear her out rather than dismissing her immediately.

The revelation becomes still more intimate when Lavinia presses her hands against the front of her dress and announces that she and Theodore are having a child together. Isabelle reacts as though the words themselves must be retractable: she shakes her head, calls the claim absurd, and cannot accept that Lavinia believes it. Her resistance is not presented as simple cruelty. It grows from the observable history she knows—months passed before Theodore left without a child, and Lavinia had believed motherhood impossible. Isabelle is defending the continuity of cause and effect that makes her own world intelligible.

Lavinia, however, treats the pregnancy as the fulfillment of her greatest wish. She had feared she would never become a mother and had been devastated by that prospect; now she is thrilled, convinced that the child is Theodore’s despite the impossible chronology. Isabelle’s skepticism therefore meets not merely a supernatural assertion but a claim to emotional and bodily reality. The disagreement places sisterly loyalty under pressure: to believe Lavinia would mean accepting a world Isabelle cannot explain, while to reject her would mean denying the experience that has given Lavinia renewed happiness.

Confession, Skepticism, and Hope

The confrontation exposes a second wound when Isabelle admits that she lied to Lavinia. After Lavinia asks whether she denies the truth, Isabelle hesitates, shakes her head, and apologizes through tears. The admission reveals that her protection of ordinary reality has already required concealment. Her lie is not treated as the end of affection; it becomes evidence of how fear, concern, and disbelief have become entangled in the sisters’ relationship.

Even after this admission, Isabelle does not surrender her rational explanation. She says that she does not believe Lavinia’s account and supposes there must be a reasonable explanation. Her position is internally divided rather than decisively converted. She can acknowledge the emotional force of Lavinia’s story without granting its supernatural premises, and she can remain loving without becoming a believer.

That divided response becomes the basis of Isabelle’s later life. She lives peacefully in Betsy’s farmhouse, surrounded by grandchildren and the comforting routines of farm life. Finding the locket brightens her world, yet she continues to believe that Lavinia invented her life with Theodore. At the same time, a deeply buried part of Isabelle looks forward to seeing her husband again and visiting the magical places in Lavinia’s stories, where she might have adventures of her own. Her disbelief thus contains a secret imaginative assent: the mind rejects the tale while the heart preserves a route into it.

Narrative Role and Significance

Isabelle functions as the story’s domestic witness and skeptical audience. Lavinia’s account could remain a private fantasy, but Isabelle’s questions, tears, accusation of lying, and continued affection give it a relational test. The supernatural is measured against a sister who knows Lavinia’s history, remembers her longing for a child, and understands the ordinary circumstances from which the extraordinary claim emerges.

Her character also broadens the meaning of family beyond conventional certainty. Isabelle’s household includes her husband, daughter, grandchildren, and Lavinia’s continuing presence in memory; it also remains imaginatively connected to Theodore, whose return she cannot accept but whose possible existence she cannot entirely stop hoping for. In that sense, Isabelle does not resolve the conflict between skepticism and belief. She makes the conflict durable, domestic, and emotionally credible: a person may reject a story as impossible while still loving the person who tells it, cherishing the object that links them, and longing for the world the story promises.
