The motif of glass and jewels represents the deceptive and fragile nature of the Lennox family’s status and traces how the family’s legitimate glass business becomes entangled with corruption. Graham’s observation that the family business is “an entire fortune built on sand” plays on the fact that glass is made from sand while also suggesting the instability beneath the family’s prosperity (25). Marjorie initially associates the glass business with her grandfather’s hard work and craftsmanship, but she later discovers that Duncan has used the factory’s resources and his knowledge of glass gem cutting to create convincing replicas of valuable jewels. The family’s legitimate industrial success therefore becomes a means of criminal deception when Duncan and Lou use fake glass gems to replace genuine jewels. This development turns glass from a product associated with Cormac’s craftsmanship into an instrument of imitation and fraud, reinforcing the theme of The Corruption Behind Wealth and Respectability.
The motif also shapes the plot as Marjorie gradually uncovers the family’s jewel racket. The blackmail of Peter Howell into swapping genuine jewels for glass replicas at the Detroit Institute of Arts demonstrates how Duncan and Lou use coercion to carry out their crimes. The suitcase of jewels concealed inside baby booties provides one of the clues that helps Marjorie uncover the extent of her family’s involvement in jewel theft. Ultimately, the fake gems become a symbol of the family’s deception: Like the replicas passed off as genuine jewels, their respectable public image conceals their criminal activities. Marjorie’s plan to sell the family their own fakes reverses this pattern, using the same method of deception that Duncan and Lou have used against others.
The Nightingale building symbolizes the tension between protection and control that underlies The Use of Psychiatric Diagnoses to Control Women. Presented as a progressive arts residency for women, it is also used as a concealed evaluation program for residents whose families have questioned their mental fitness. On the surface, it offers freedom, resources, and community—a sanctuary where women can pursue their creative passions. Yet the residents are not told that they are also being observed and evaluated, creating a contradiction between the program’s protective purpose and its lack of informed consent. Juliette intends the Nightingale to protect women from unjust institutionalization, but the elaborate rules of the “lease,” Dock’s observation of the residents, and restrictions on their movement also limit their autonomy. The building therefore combines opportunities for creative independence with forms of supervision that the residents have not knowingly accepted.
The building’s contradictory purpose becomes clear when Marjorie discovers the residents’ files, which include the alleged diagnosis of “Chronic Imaginative Derangement” beside her artistic discipline as a clothing designer (197). This discovery reveals that her creativity exists alongside a psychiatric label connected to her family’s concerns about her mental fitness, although she has not been told that she is being evaluated. Juliette Bonafante’s personal history of being wrongfully confined by her own father after behavioral changes caused by an impacted tooth explains her determination to protect other women from being institutionalized without proper evaluation. The building’s name reinforces this purpose: Marjorie recognizes that Juliette identifies with Florence Nightingale, a symbol of “healing and devotion” (206). Yet the secrecy surrounding the evaluations complicates that association, making the Nightingale a symbol of the tension between protecting women and respecting their autonomy.
The recurring motif of keys and locked doors represents the tension between safety and restriction at the Nightingale. Throughout the residents’ time at the Nightingale, Dock’s repeated insistence is that the doors must be locked at all times. While framed as a safety measure against the dangers of Detroit, the rule forms part of the wider restrictions governing the residents’ movement within the program. As Marjorie gradually questions the rules and later discovers that the residents are being evaluated without their knowledge, the locked doors acquire a more troubling significance. What initially appears to provide security also reflects the limits placed on the women’s autonomy, connecting the motif to the use of psychiatric diagnoses to control women. The locks therefore make the tension between protection and restriction physically present within the residents’ everyday lives.
The silver keys complicate the purpose of the locked doors by giving residents access to spaces that are otherwise closed to them. Bernice uses her silver key to enter the playwright’s apartment after Ivy discovers that the residents’ silver keys open one another’s doors, while Marjorie later uses hers to enter Ivy’s room after her disappearance. The keys therefore provide access to other residents and to information that would otherwise remain behind locked doors, showing that the same system that restricts movement can also create unexpected points of access. The motif reaches its final reversal when Marjorie leaves the Nightingale after discovering the truth about the program: She deliberately does not lock her apartment or the front door and takes the keys with her. Her rejection of the locking routine marks her refusal to continue submitting to the rules that have governed her movement and access throughout the residency.
Throughout the novel, clothing and costumes serve as a recurring motif through which characters shape how they present themselves and how others perceive them, directly connecting to the theme of Art as a Source of Identity and Independence. For Marjorie, fashion design allows her to give visible form to ideas that often conflict with her family’s expectations. Her imaginative creations, from the controversial “tree” costume to the nature-inspired dresses she develops at the Nightingale, show her willingness to experiment with clothing despite criticism of both her behavior and her artistic ambitions. At the Nightingale, this experimentation develops into a more deliberate fashion practice as she begins creating a line of garments. When a representative from Himelhoch’s department store praises her dress and expresses interest in her other designs, Marjorie receives professional recognition for work her family has treated as unsuitable. Clothing therefore reflects both her individual artistic vision and her growing ability to present that vision beyond the expectations of her family.
Marjorie’s use of clothing as self-expression is contrasted with instances in which clothing alters, conceals, or imposes a social identity. After his disappearance, while living under the name Jack Howell, Peter Howell adopts a bland suit, shorter hair, and a subdued appearance that sharply contrasts with his earlier distinctive style. Likewise, Slorah’s ill-fitting party dress is part of a role imposed on her by Duncan, who orders her and Atchison to dress as guests and pretend to be a couple. Marjorie’s designs, by contrast, allow her friends to shape how they present themselves to others. Dock describes one of her creations as “transformative” when he sees Bernice wearing it, while Ivy embraces the “Christmas tree” dress, whose imagery connects with her personal attachment to Christmas and memories of her mother. The motif therefore shows how clothing can reflect self-expression, concealment, or an imposed role, depending on the circumstances in which a character’s appearance is constructed.
