The Locked Trunk: Secrets and Inheritance in Banyan Moon

The locked trunk in Banyan Moon is a silver metal container that appears across several chapters, holding a photograph of Bình and a red dress. More than a storage box, it becomes the physical repository for the family’s most guarded secret: Hương’s biological father. Thao Thai uses the trunk to explore how hidden truths shape the relationships between Minh, Hương, and Ann, and to examine the novel’s central themes of intergenerational trauma and secrets and mother-daughter relationships.

What the Trunk Literally Is

The trunk is described as a “shoddy thing that had been beaten down from wear” (Chapter 31). It is locked with a small key, and its contents are deliberately hidden from the family. Inside, Minh places a photograph of Bình—Hương’s biological father—and a red dress once owned by Minh. The trunk first appears in the narrative when Hương discovers it in her apartment closet shortly after marrying Vinh, and later resurfaces when Minh hides it in the attic of the Banyan House.

Where the Trunk Recurs

Chapter 24 (Hương, 1990): Hương finds the trunk in Vinh’s closet and asks him about it. Vinh denies ownership and reacts with violence, throwing objects at Hương. This scene establishes the trunk as a catalyst for marital conflict and a symbol of forbidden knowledge.
Chapter 31 (Minh, 1990): Minh brings the trunk to Hương’s apartment while the couple is on honeymoon and hides it in the guest room closet. She later moves it to the Banyan House attic after Hương returns with baby Ann. Minh reflects that hiding the trunk felt “like a burial.”
Chapter 29 (Ann): After Minh’s death, Ann finds a small key in Minh’s jewelry safe, along with a note reading “Gác xép” (attic). She retrieves the trunk from the attic and opens it, discovering the photograph and dress that reveal the secret of Hương’s parentage.
Chapter 39 (Ann): After the fire destroys the Banyan House, Ann and Hương move to a smaller cottage. Ann notes that in their new home there are “no locked trunks with hidden keys,” signaling the family’s decision to release old secrets.

How the Trunk’s Meaning Changes

The trunk’s significance evolves across the three generations:

For Minh: The trunk represents guilt and a failed chance at honesty. She brings it to Hương’s apartment hoping to prompt a conversation about Bình, but when the moment passes, she buries the truth in the attic. To Minh, the trunk is a “bread crumb back to the past” that she ultimately cannot follow.
For Hương: The trunk is first a source of marital suspicion and later an object of resentment. She never opens it, preferring to ignore its existence. The trunk embodies the painful gap between what she knows and what she is willing to confront.
For Ann: The trunk becomes an inheritance of knowledge. When she opens it, she chooses to face the truth rather than repeat her grandmother’s pattern of concealment. Ann’s decision to keep the secret from Hương temporarily, but eventually to create a children’s book with a revised legend, suggests a symbolic transformation of the trunk’s contents from burden to story.

Character and Theme Connections

The trunk connects directly to the theme of survival and sacrifice: Minh sacrifices openness to protect Hương; Hương sacrifices her curiosity to preserve her marriage. The trunk also fuels the grief and healing arc—Ann’s act of opening the trunk is a step toward healing the rift between herself and her mother. The photograph of Bình ties into identity and belonging, as Hương’s unknown paternity haunts her sense of self.

Key character links:

Minh: The trunk is her creation; she controls the secret and its hiding place.
Hương: She discovers the trunk but never learns its contents during Minh’s lifetime.
Ann: She finds the key, opens the trunk, and decides what to do with the knowledge.
Bình (Kumquat): The photograph inside the trunk reveals his identity as Hương’s biological father, linking him to Vinh.

Study Questions with Answers

Why does Minh choose to hide the trunk in the attic rather than destroy it or give it to Hương?
- Minh keeps the trunk because she hopes it will eventually provoke a disclosure about Hương’s father. She also feels unable to tell the truth directly. The attic represents a middle ground—neither destroyed nor fully accessible. (See Chapter 31: “I suppose if she had asked me about it, I might have told her the truth about her father…”) This aligns with the theme of intergenerational trauma and secrets.
How does Ann’s decision to open the trunk affect her relationship with Hương?
- Opening the trunk gives Ann knowledge that she initially withholds from Hương. She decides not to share the secret immediately, reflecting the same pattern of concealment she criticizes. However, by the end of the novel, Ann’s choice to rewrite the moon legend and name her son Bình signals a move toward openness and reconciliation. (See Chapter 29: “I’ll stay with my mother… I want desperately to know her—for Kumquat to know her—without the wedge of my grandmother between us.”)
What role does violence play in the trunk’s first appearance (Chapter 24)?
- Hương’s inquiry about the trunk triggers Vinh’s violent outburst. He throws objects at her, including a metal ashtray that cuts her lip. The trunk becomes a signpost for the dangerous limits of secrecy within marriage. Vinh’s denial—“There is no trunk. If there is, it’s not mine”—shows how secrets can be weaponized to control a partner. This connects to the theme of survival and sacrifice, as Hương endures abuse to preserve the relationship.
How does the trunk’s location shift reflect the family’s emotional journey?
- The trunk moves from Vinh’s closet (marriage ownership) to the Banyan House attic (burial and neglect) and finally back to Ann’s hands (reclamation). Each location marks a stage in the family’s relationship with truth: hidden in the marriage, suppressed in the grandmother’s home, and retrieved by the granddaughter. In Chapter 39, after the fire, Ann notes the absence of locked trunks, signaling the family’s release from the hold of the past.
