“Look here, Watson,” Holmes said after we finished lunch. “Please sit down. I want to talk to you. I don’t know what to do, and your advice is important to me. You smoke your cigar (雪茄烟) while I explain.”

“Please continue,” I said, as I lit my cigar.

“Now there’re a few important points in young James’ story. One, his father cries Coo-ee before he sees him. Two, he talks about a rat (老鼠). I think young James is telling the truth (真相).”

“So why did Mr. McCarthy shout Coo-ee then?”

“Well, he was not shouting Coo-ee to his son. It was by chance that James heard. The Coo-ee was to call the person he was meeting. But Coo-ee is an Australian cry, Australians usually say it when they meet to catch attention. Perhaps Mr. McCarthy was meeting someone from Australia.”

“I see. But why did he talk about a rat, then?” I asked.

Holmes took a piece of paper from his pocket and put it on the table.

“This is a map of Australia,” he said. He put his hand over part of the map. “Now, Watson, what can you read there?” he asked me.

“ARAT,” I read.

“And now?” Holmes moved his hand.

“BALLARAT,” I read.

“Yes. That was the word the dead man said. It’s a place called Ballarat. His son only heard the ‘rat’ part of the word. Old Mr. McCarthy was trying to say where his murderer was from, the town of Ballarat. The grey cloak is point No. 3. If James is telling the truth, there was a grey cloak (斗篷). So now we have an Australian from Ballarat with a grey cloak.”

“Great!” I replied.

“And it’s someone who lives nearby, as the Boscombe Pool isn’t open to the public. Only people from the farm nearby or the Turner house can go there,” said Holmes.

“That’s wonderful, Holmes!” I exclaimed.

Old people in Changsha are happy. In the morning you can see old people play sports in the park. Mr. and Mrs. Chen are always among them after their sons and daughters go to work and grandchildren go to school. Mr. Chen is in a sports club. There he can run, swim and play ball games. Their friends Mr. and Mrs. Zhang aren't in any clubs. They play computer games at home because they want to learn a lot about(了解）their grandchildren. Their grandchildren all love then very much. These days some old people want to have a Shopping Club. In the club they can talk about how to buy cheap things.

How happy the old people in Changsha are! They all think they are lucky to live in a place like Changsha.

One day, I took my two kids to a playground. As soon as we got there, my daughter ran to the swing and asked for a push (推). When I was helping my daughter go higher, I saw another girl trying to make her swing go higher. But it was quite difficult for her.

I gave my daughter one big push and then walked to the girl. I asked her if she wanted me to push her. She said, “Yes!” For the next two hours, I pushed swings and played with my children and the girl. When we went back home, I was very tired, but I felt happy.

Two years later, I was always tired after a long day’s work. But every day, I needed to pick up my kids before going home. One day, when I stood in the parents’ waiting area (区), a girl hugged (拥抱) me. I looked down and found she was the girl on the playground. She gave me one big hug before getting on the school bus. As I watched her back, I didn’t feel tired anymore.

In life, the love we give to others will find its way back to us again.
