"The Sign of Four" is one of the stories based on the figure of Sherlock Holmes.

Sherlock Holmes was the most famous detective in London and for him his work was a very important thing in his life.

At the beginning the story told is about Watson, who was Sherlock’s friend and also an important aid in his cases.

In the past Watson worked as a doctor in the British army. In a mission he nearly died and so decided to retire and came back to England.

It was a boring day when a woman went to Holmes’ house to speak with him.

Miss Morston missed her father many years ago (? did her father die) . Recently she received a letter with an invite to come to the theatre without the police. There she will meet the writer of the letter.

Therefore, she sought the help of Sherlock and Watson to discover where her father was and also to know why she received a pearl from a mysterious man. Was there a connection between these two things?

So they went to the appointment at the theatre and afterwards followed the man there who brought them to a person named Thaddeus Sholto’s house.

Thaddeus Sholto’s father was a friend of Miss Morston’s father.

Thaddeus told them that Miss Morston's father died after a terrible argument with his father. The argument was about the discovery of the Agra Treasure that they have had done together some years ago.

A course I want to take

Could you help me correct my mistakes？thanks！

The course I want to take is Miss Wang’s badminton course. She was an athlete. She retired from the National Badminton Team and now she is my college’s teacher. I have been in her class before. I think she is the best badminton teacher in my college. But unfortunately, she was not an eligible teacher to launch the course because of the new rules which said teachers who want to launch courses need to have their own published paper. Miss Wang focuses on real sports so she doesn’t have one. I want to take her course because she has a great training method to help us improve. She uses an advanced and professional theory. Through learning from her, we can improve our skill.
