Study on the scarlet letter: the first meeting between Dr. Watson and Fowles, and his first participation in a bizarre lead murder solved by Sherlock Holmes. The murders occurred in succession at No.3 Laurenston Garden and Holiday Hotel. The modus operandi is grotesque: there are no scars on the deceased, and the word "revenge" is still left at the scene of the crime. Holmes started with the words in Blood and Caution, conducted investigation and reasoning, and finally found out that the murderer's name was Jefferson Hope. Hou Bo's fiancee was forced by a screwdriver, which caused her father and daughter to die in hatred. In order to avenge this vendetta, Hou Bo took pains to track down Drebber and his secretary, and finally forced him to take the magic to poison him, leaving bloody words on the wall and the face of the deceased.

The hound of the Baskerville describes a mysterious, bizarre and complicated tragedy. A dog is trained to kill because of swallowing huge property.

One day, Dr Mortimer came to Holmes' office with an old manuscript handed down by the Baskerville family. It tells the bizarre story that his ancestors were killed by a vicious dog in a crime, and several generations of this family were rewarded by evil. Sir Childs recently died in the same way in a rural swamp not far from London.

Mortimer was worried that Sir Henry, who had just returned from Canada and inherited his inheritance, would also suffer bad luck. Sure enough, as soon as Henry arrived in London, he received a threatening letter.

In order to ensure Henry's safety, Holmes sent Watson to Baskerville Hall.

A man named Stapleton greeted Watson when he went out for a walk. Watson accepted the invitation to visit his manor. And learned that the housekeeper's wife and brother escaped from prison and hid in the swamp.

At this time, Holmes also came here for a secret investigation. Just then, a terrible scream pierced the night sky. "It's a hunting dog!" Cried Holmes. They ran out and saw a man fall to the ground with a gulp. Wearing Henry's old clothes are the housekeeper's wife and brother.

Holmes decided to close the net, so he pretended to return to London, let Henry visit Stapleton's manor in the evening, and then went home alone.

In the afternoon 10, the swamp was shrouded in fog. Henry walked to the rock where sherlock holmes and his family were hiding.

Holmes pulled open the safety of the pistol. A terrible big hunting dog seems to be on fire in his mouth and chasing Henry like an arrow.

Holmes and Watson's pistols fired at the same time ...

As it turned out, the killers were the Stapletons.

The Four Signs describes a tragedy surrounding the struggle for Agrander's treasures. The Englishman Smallville and three black Indians seized a box of treasure worth 500 thousand pounds in the war. They hid the treasure and swore to keep it a secret, but they were sentenced to prison for murder. In order to be free, Smallville took advantage of Major Schulto's gambling loss and offered to give the major one-fifth of the treasure and asked him to help him escape. Unexpectedly, the major was treacherous and returned to England alone with the treasure. Smoot bore a grudge and endured the hardships of hard labor, and finally fled back to London with the help of St. Van Gogh. Smoot seeks revenge, and after Schulto's death, he seeks treasure, which leads to the tragedy of Sakuranuma Villa and kills Schulto's son. In order to defend his oath, Smallville left a note with his and three Indian black names on it after committing the crime. This is the so-called "four characteristics".
