The quiet opulence of the Corbin estate in Illinois is thrown into turmoil on the eve of Judith Corbin’s society wedding, when the legendary family pearl necklace disappears from her grandmother’s old safe. Written in crisp, natural prose, the story follows the quiet unraveling of aristocratic composure as dark family secrets emerge from the shadows. The formidable old matriarch rules her household with an iron fist, while her daughter Victoria struggles desperately to maintain appearances and shield her children from financial ruin and social disgrace. Meanwhile, Judith's thirteen-year-old brother, Punch, takes on the role of an earnest amateur detective, obsessively tracking clues and guarding the premises against imagined intruders.
The arrival of long-lost Uncle Alec from the Philippines and the unexpected appearance of brilliant, eccentric connoisseurs add layers of intrigue to the tense household dynamics. As various members of the family and guests fall under suspicion—including Judith's seemingly correct fiancé, Bruce Applebury, and a mysterious professional thief hiding within the very walls of the mansion—the boundaries between propriety and criminality blur. Through a series of sharp psychological clashes and subtle revelations, the narrative builds toward a startling confrontation that tests the true loyalties of everyone involved. The narrative deftly balances a witty social critique of the American upper class with a genuinely baffling puzzle of theft, identity, and unspoken motives. The climax unmasks the culprit behind the labyrinthine plot, restoring the famous pearls to their rightful place and allowing the younger generation to break free from the suffocating traditions of the past.
