Books in Arthur Conan Doyle Collection series

Jabez Wilson, a London pawnbroker, comes to consult Sherlock Holmes and Doctor Watson. While studying his client, both Holmes and Watson notice his red hair, which has a distinct flame-like hue. Wilson tells them that some weeks before his young assistant, Vincent Spaulding, urged him to respond to a newspaper want-ad offering work to only red-headed male applicants. The next morning, Wilson had waited in a long line of fellow red-headed men, was interviewed and was the only applicant hired, because none of the other applicants qualified; their red hair was either too dark or too bright, and did not match Wilson's unique flame color. Wilson tells Holmes that his business has been struggling. Since his pawn shop did most of its business in the evenings, he was able to vacate his shop for short periods in the afternoon, receiving £4 a week for several weeks (equal to £380/week today);[1] the work was obviously useless clerical work in a bare office, only performed for nominal compliance with a will, whereupon he was made to copy the Encyclopædia Britannica. Wilson learned much about the subjects starting with the "A" version and looked forward to getting into the "B" section. One morning, a sign on the locked office door inexplicably announced that "THE RED-HEADED LEAGUE IS DISSOLVED." Wilson went to the landlord, who said that he had never heard of Duncan Ross, the person who managed the league office. The landlord did remember the tenant with scarlet hair and gives him a card which directs Wilson to an artificial knee company. Wilson ends the story with how frustrated he is losing the £4 a week. Holmes and Watson laugh at Wilson because of the ridiculous situation, but Holmes assures him that by Monday they will solve the case. Wilson leaves after having given the detective a description of Spaulding; Holmes decides to go and see Spaulding, whom Holmes notices has dirty trouser knees. Holmes then taps on the pavement in front of the pawnbroker's shop. With the case solved, he calls Police Inspector Jones and Mr. Merryweather, a director of the bank located next door. The four hide themselves in the bank vault and confront the thieves when they show up. They are John Clay, who has a long history of criminal activity already, and his helper Archie. Under the alias of Spaulding and Ross, they had contrived the 'Red-Headed League' rigmarole to keep Wilson out of his shop while they dug in the basement, in order to break into the bank vault next door. Although paying Jabez Wilson four pounds a week was expensive, it was a pittance compared to the ill-gotten thousands they were looking to steal from the bank. Back at Baker Street, Holmes explains to Watson how he solved the case.

Watson visits his friend Holmes at Christmas time and finds him contemplating a battered old hat, brought to him by the commissionaire Peterson after the hat and a Christmas goose had been dropped by a man in a scuffle with some street ruffians. Peterson takes the goose home to eat, but later returns to Holmes with a blue carbuncle his wife had found in the bird's crop (throat). Holmes makes some interesting deductions concerning the owner of the hat from simple observations of its condition, conclusions amply confirmed when an advertisement for the owner produces the man himself: Henry Baker. Holmes cannot resist such an intriguing mystery, and he and Watson set out across the city to determine exactly how the jewel, stolen from the Countess of Morcar during her stay at a hotel, wound up in a goose's crop. The man who dropped the goose, Mr. Henry Baker, comes to reclaim his hat in response to Holmes' advertisement. Holmes drops hints about how he saved the "innards" of the goose, but Baker fails to respond to them, simply saying that he is afraid goose remains are not much use. He does, however, give Holmes valuable information, eventually leading him to the conclusive stage of his investigation, at Covent Garden. Holmes offers a fresh goose to Henry Baker, who responds with gladness and departs, whereupon Holmes tells Watson that Baker is eliminated from the suspect list as he obviously knows nothing about the carbuncle. At Covent Garden, a salesman named Breckinridge gets angry with Holmes, complaining about all the people who have pestered him about geese sold recently to the landlord of the Alpha Inn. Clearly, someone else knows that the carbuncle was in a goose and is looking for the bird.

Holmes' client is Helen Stoner, a 32-year-old spinster who lives with her stepfather: Dr. Grimesby Roylott of Stoke Moran. Dr Roylott is the last survivor of what was a wealthy but dissolute and violent tempered aristocratic Anglo-Saxon family of Surrey. After returning from India where he had a large medical practice and had served a jail sentence for killing his native Butler in a fit of rage, Roylott—a widower—settles with his two stepdaughters in the broken-down ancestral manor-all that is left of estates that had extended into Berkshire and Hampshire. The doctor becomes notorious for terrorizing the local village because of his quarrelsome personality and violent temper. Dr. Roylott has required Miss Stoner, who is engaged to be married, to move into a particular bedroom of his heavily mortgaged ancestral home in Stoke Moran. This room was the one in which two years before, Helen's twin sister Julia had died under mysterious and dramatic circumstances—uttering the last words "The band! The speckled band!"—just prior to her wedding. Helen is reluctant to sleep in the room because a number of things about the bedroom are mysterious and disturbing. Late at night, Helen hears low whistling sounds followed by a metallic clang. There is a strange bell cord over the bed but it does not appear to work any bell. The rope goes to a ventilator—an opening high in the wall of the room, close to the ceiling—which provides air circulation between Helen's room and an adjacent room of Dr Roylott in the crumbling mansion. In addition, Helen's bed is clamped to the floor; this piece of furniture can never be moved from its position. Stoner surmises that Julia might have been murdered by the gypsies who wear speckled handkerchiefs around their necks, in order to bring in a bit of cash. Dr. Roylott has rented spare rooms in Stoke Moran near them. A cheetah and a baboon also have the run of the property, for Dr. Roylott keeps exotic pets from India.

Dr Watson is called upon late at night by a female friend of his wife. Her husband has been absent for several days and, as he is an opium addict, she is sure he has been indulging in a lengthy drug binge in a dangerous East End opium den. Frantic with worry, she seeks Dr. Watson's help in fetching him home. Watson does this, but he also finds his friend Sherlock Holmes in the den, disguised as an old man, trying to extract information about a new case from the addicts in the den. Mr. Neville St. Clair, a respectable and punctual country businessman, disappears. Making the matter more mysterious is that Mrs. St. Clair is sure that she saw her husband at a second-floor window of the opium den, in Upper Swandam Lane, a rough part of town near the docks. He withdrew into the window immediately, and Mrs. St. Clair is sure that there is something wrong. She tries to enter the building, but her way is blocked by the opium den's owner, a lascar. She fetches the police, but they cannot find Mr. St. Clair. The room, in the window of which she saw her husband, is that of a dirty, disfigured beggar known to the police as Hugh Boone. The police are about to put this report down as a mistake of some kind when Mrs. St. Clair spots and identifies a box of wooden bricks that her husband said he would buy for their son. A further search turns up some of her husband's clothes. Later, his coat, with the pockets full of several pounds' worth of pennies and halfpennies, is found in the Thames, just below the building. The beggar is arrested and locked up at the police station, and Holmes initially is quite convinced that Mr. St. Clair has been the unfortunate victim of murder. However, several days after Mr. St. Clair's disappearance, his wife receives a letter in his own writing. The arrival of this letter forces Holmes to reconsider his conclusions, leading him eventually to an extraordinary solution. Taking a bath sponge to the police station in a Gladstone bag, Holmes washes Boone's still-dirty face, causing his face to be revealed — the face of Neville St. Clair! Upon Mr. St. Clair's immediate confession, this solves the mystery, and creates a few problems.
