Summary

Frobisher stands at the end of a Soho street, coat collar up and hat brim down, believing he is skilled at blending into the background—like H. G. Wells’s Invisible Man. Unbeknownst to him, a man holding a police-issue notebook has been observing him since the previous day. The notebook records Frobisher’s mundane routine: leaving his Ealing home at 6:20 a.m., arriving at Bow Street at 7:45 a.m., walking around Soho and Covent Garden at midday, and eating ham and chips at Jonnie’s in Floral Street.

Frobisher has been monitoring the Amethyst nightclub nearly every night since starting at Bow Street, hoping to catch Maddox entering through a second secret entrance he suspects exists but has failed to locate. As he watches, a girl—perhaps thirteen to fifteen years old, with blonde ringlets and a cheap spangled dress—steps into the lamplight, looking restless and expectant. Frobisher considers approaching her to warn her away, but a cab arrives with a noisy group, and by the time they enter the club, the girl has vanished into the night.

Later, Miss Kelling and Cobb arrive. Cobb, a skinny man out of uniform, wears an ill-fitting hired evening suit paid for from Bow Street funds. Frobisher doubts Cobb is the right man for the job, though he acknowledges Cobb’s keenness. Reluctantly, Frobisher heads to the Tube station, reflecting that people stay out carousing to avoid going home.

Back at home, Frobisher finds Lottie asleep in her chair. The lid of her sewing table is open, and inside, among skeins of vibrant wool, lie a needle and an empty syringe—evidence that she has resumed using morphine. Frobisher removes the needle and syringe, closes the lid, and covers her with a blanket. He notices the tulips he bought have already wilted, their petals gaping open, and he thinks it serves him right for buying them cheaply.

Character Development

Frobisher: This chapter deepens his character by contrasting his professional vigilance with personal blindness. He prides himself on being invisible, yet he is being observed. His concern for the girl shows a protective instinct, while his reaction to Lottie’s relapse reveals resignation and a sense of inevitability. His reflection on why people stay out carousing suggests a growing understanding of escapism, even as he disapproves of it.
Lottie: Though she appears only asleep, the discovery of the needle and syringe signals a relapse into addiction, underscoring her vulnerability and the fragility of her recovery.
Cobb: His ill-fitting hired suit and Frobisher’s doubts about his suitability highlight his inexperience and the awkwardness of his undercover role.
Miss Kelling: Her presence at the club and her reaction to Cobb being called “sensible” hint at her own standards and perhaps a degree of irritation or disappointment.

Themes, Symbols, or Motifs

Surveillance and Invisibility: Frobisher believes he is invisible, but the chapter reveals he is being watched, creating dramatic irony. The police-issue notebook symbolizes the bureaucratic surveillance that pervades the world, while Frobisher’s own surveillance of the club is mirrored by the spy’s surveillance of him.
Post-war Hedonism and Disillusionment: The club’s endless procession of patrons seeking indulgence reflects the post-war hedonism Frobisher observes. His comment that the war made people hedonistic, and his belief that they should have embraced calm sobriety, underscores his disillusionment with the era’s excesses.
Addiction and Domestic Decay: Lottie’s relapse into morphine use, symbolized by the needle and syringe hidden among her sewing materials, represents domestic decay and the failure of recovery. The wilted tulips serve as a symbol of neglect and the cheapness of his attempts to bring beauty home.
Youth Vulnerability: The girl under the lamppost, described as a “wraith,” highlights the vulnerability of young people in the nightclub world. Frobisher’s impulse to warn her away shows his awareness of the dangers she faces.

Why This Chapter Matters

This chapter humanizes Frobisher, moving him from a mere investigator to a man with personal struggles and blind spots. His self-image as an invisible observer is undercut by the revelation that he is himself under surveillance, adding a layer of irony and foreshadowing potential consequences. The discovery of Lottie’s relapse introduces a personal stake that may affect his professional judgment. The chapter also reinforces key themes of post-war disillusionment and the allure of escapism, while the fleeting appearance of the girl hints at broader social concerns. It sets up future developments by introducing the spy and deepening Frobisher’s internal conflicts.

Study Questions and Answers

How does Frobisher’s self-perception as “invisible” contrast with the reality of his being observed?

Frobisher believes he is skilled at blending into the background, comparing himself to the Invisible Man. However, the chapter reveals he is being watched by a man with a police-issue notebook, who has been recording his movements since the previous day. This contrast highlights Frobisher’s lack of awareness and the irony of his confidence in his own invisibility.

What does Frobisher’s reaction to the girl under the lamppost reveal about his character?

Frobisher notices the girl’s nervousness and vulnerability, and he considers approaching her to tell her to run home. This impulse shows his protective instincts and concern for young people, but he hesitates, and she disappears when a cab arrives. His failure to act suggests a conflict between his sense of duty and his reluctance to intervene, reflecting his broader passivity in the face of societal decay.

What does the discovery of the needle and syringe in Lottie’s sewing table signify, and how does Frobisher respond?

The needle and empty syringe indicate that Lottie has resumed using morphine, a relapse into addiction. Frobisher removes them and covers her with a blanket, but his reaction is one of dulled inevitability rather than surprise or anger. He wonders who is supplying her, but he does not confront her, suggesting resignation and a sense of helplessness in dealing with her disintegration.
