A prominent banker, Alexander Holder, seeks the help of a renowned detective after a disastrous incident involving a valuable coronet. Holder had lent £50,000 to a nobleman, secured by the Beryl Coronet, a national treasure. After securing the coronet in his home, he discovers it damaged and three of its precious stones missing. In a fit of rage, he accuses his son, Arthur, of theft after catching him with the coronet in his hands. Despite the evidence, Arthur maintains his innocence, leading to a family crisis. The banker, distraught over the potential scandal and loss of honor, turns to the detective for assistance. Holmes, skeptical of the straightforward interpretation of events, investigates the case further. Holmes deduces that the situation is more complex than it appears. He examines the scene, noting the absence of any signs of forced entry and the peculiar behavior of the household staff. He learns that a maid, Lucy, has a suitor with a wooden leg, which raises suspicions about her involvement. As Holmes delves deeper, he uncovers a secret relationship between Arthur's cousin, Mary, and Sir George Burnwell, a known gambler and rogue. He theorizes that Mary, in collusion with Burnwell, orchestrated the theft of the coronet. The night of the incident, Mary had communicated with Burnwell through a window, leading to a confrontation between him and Arthur. Holmes reconstructs the events, revealing that Arthur had pursued Burnwell after witnessing the handoff of the coronet. In the struggle, Arthur inadvertently damaged the coronet while trying to retrieve it. Holmes's investigation leads him to confront Burnwell, who initially denies involvement but eventually reveals that he sold the stolen gems to a receiver. In the end, Holmes retrieves the missing stones and returns them to Holder, who is overwhelmed with relief. He realizes his son’s innocence and the true nature of the events that transpired. However, Mary’s fate remains uncertain, as she has fled with Burnwell, leaving her future ambiguous. The case concludes with the banker expressing gratitude to Holmes for his skill in resolving the matter and restoring his honor.
