Plot Summary

The Mysterious Client

Miss Morstan seeks Holmes' help

Sherlock Holmes and Dr. Watson are approached by Miss Mary Morstan, who presents a perplexing case involving her missing father and a series of mysterious pearls sent to her annually. Her father, Captain Morstan, disappeared ten years ago after returning from India. Recently, she received a letter inviting her to a meeting, promising justice for a wrong done to her. Holmes, intrigued by the mystery, agrees to accompany her, along with Watson, to the meeting.

The Hidden Treasure

A tale of lost riches

At the meeting, they encounter Thaddeus Sholto, who reveals that his father, Major Sholto, was involved in a treasure dispute with Captain Morstan. Major Sholto died without revealing the treasure's location, but Thaddeus believes it is hidden at Pondicherry Lodge. He has been sending the pearls to Miss Morstan as a gesture of goodwill. The group decides to visit the lodge to uncover the truth about the treasure.

The Sinister Plot

A murder and a map

Upon arriving at Pondicherry Lodge, they find Bartholomew Sholto dead in a locked room, with a note reading "The Sign of Four." Holmes deduces that the murder is linked to the treasure and involves a wooden-legged man and a mysterious accomplice. They discover a map indicating the treasure's location, but the treasure itself is missing. Holmes sets out to track down the culprits using his keen deductive skills.

The Chase Begins

Pursuit of the suspects

Holmes and Watson, with the help of a dog named Toby, follow the scent of creosote left by the wooden-legged man. Their pursuit leads them through the streets of London, eventually discovering that the suspects have taken to the river in a steam launch. Holmes enlists the help of the Baker Street Irregulars, a group of street children, to gather information on the launch's whereabouts.

The Tragic Discovery

A deadly confrontation

The chase culminates in a dramatic pursuit on the Thames, where Holmes and Watson confront the suspects aboard the steam launch. A fierce struggle ensues, resulting in the death of the accomplice, a small Andaman Islander named Tonga. The wooden-legged man, Jonathan Small, is captured, and the treasure chest is recovered. However, upon opening it, they find it empty, the jewels having been scattered into the river.

The Unraveling Mystery

Jonathan Small's confession

Jonathan Small is brought to Holmes' rooms, where he recounts his story. He explains how he and three other convicts discovered the treasure in India and made a pact to share it. Betrayed by Major Sholto, who took the treasure for himself, Small sought revenge. He reveals that he scattered the jewels to prevent anyone else from possessing them, believing they brought only misfortune.

The Final Confrontation

Justice and resolution

With the case solved, Holmes reflects on the nature of justice and the futility of greed. Miss Morstan, relieved of the burden of the treasure, accepts Watson's proposal, bringing a personal resolution to the story. Holmes, ever the detective, finds satisfaction in the intellectual challenge of the case, though he laments the lack of tangible reward.

Analysis

Themes of justice, greed, and colonialism
