Holmes rubbed his hands together excitedly. His eyes shone and he leant forward in his chair.
"Tell us your story," he said.
Miss Morstan began her story and we listened.
"My father," she began," was a captain in the army. When I was very young, he was sent to India My mother was dead and I had no other relatives in England. So, while my father was away, I was sent to school."
"When I was seventeen, I received a letter from my father. He said that he was leaving India and coming back to England. He gave me the address of a hotel in London. He asked me to meet him there."
"I was very happy and excited about seeing my dear father again, I went to London and arrived at the hotel. I asked for Captain Morstan, my father. But I was told by the hotel manager that my father was not there. He had gone out the night before and not returned."
"I waited all day and all night, but my father didn't come back to the hotel. Finally, I went to the police. They advertised for Captain Morstan in all the newspapers, but without success. I never saw my dear father again."
…
"Four years after my father disappeared," continued Miss Morstan, "I saw an advertisement in the newspaper. The date was 4th May 1882. To my surprise, the advertisement asked for the address of Miss Mary Morstan, It said that ifl advertised my address, I would receive some very good news."
"What did you do?" asked Holmes.
"I advertised my address in the same newspaper. The next day, I received a small cardboard box. Inside the box was a lovely pearl（珍珠）． And I have received another five pearls since that day. They arrive every year on the same day. Look."
She opened a flat box and showed us six beautiful pearls.
"_______" asked Holmes.
"Nothing at all," replied Miss Morstan. Then she continued. "But the strangest thing of all happened this morning. That is why I came to see you. This morning, I received a letter. Please read it."
"Thank you," said Holmes. He took the letter and studied it carefully,
