Solve the Clue & The End of Mystery of Boscombe Pool

     After we arrive at the hotel, I tell Watson about the clue of this case. In the beginning, we have two things that we both notice; “Cooee” sound and a rat. Clearly that father was not calling his son because he knew that his son is not here. But James heard this sound, so he thought that his father called him. “Cooee” is for the person that old McCarthy was going to meet. Also, “Cooee” is a special call that Australians use. The second is rat. I take off an Australia map and fix it out to the word “BALLARAT.” This should be the BALLARAT because his father wanted to tell the name of murderer but James only understood the last part of the word ‘A RAT.’  

     I know that the murderer was tall because I found the space between footmarks was long and the marks also told what kind of boots he wore. Furthermore, the mark on the right foot was less clear than left foot. It showed that he stood more heavily on the left because his right leg hurt him. Also, I found the ash from the cigar under the tree, it was an Indian cigar from shop in Rotterdam. And he use cigar-holder, I known because the end of cigar was cut off, not bitten off and the cut is not clear, so the pocket-knife is not a sharp one.

     Now, there is a visitor, Mr. John Tuner, he looks very seriously ill. He got my message that I want to see him, so he comes. He already knows that why he has to come, he feels guilty that he made young McCarthy get hurt. So, he will tell us everything.

     John Tuner starts telling us by describe the dead man is a true criminal, bad in every possible way. “He has sat on my back for twenty years and made my life impossible. Now, I will tell you how I met him. When I was in Australia, I and my friends, we are a gangster. Black Jack of Ballarat was the name I took and in Australia people still remember our group as the Ballarat Boys. One day, there was a carriage was carrying gold, so we hid beside and took it by surprise. After we got gold, we decided to let the driver of that carriage go. The driver of the carriage is McCarthy. After that I became a rich man and back to England. I stop doing the bad thing and become a better man after Alice was born," John Tuner said.

     "On day in London, I met McCarthy by accident, he seem did not have anything such as shoes and coat on his back. He started the conversation that if I will not take care of them, McCarthy and his son, he will tell that story to the police," John Tuner said.

     "So, I let them live at my farm and they lived without paying. He asked for everything and I have to give it to him such as a house, a carriage or money. Also, he asked me that he wanted my daughter and his son married. But there is something that I could not give him is my daughter because if they are married, young McCarthy will get everything. I did not hate the boy but his father’s blood is in him. So, McCarthy was ready to go to the police, so I decide to meet him at the pool to have an agreement one more time," John Tuner said.

     "When I went there I saw McCarthy and his son was having a quarrel about Alice. I hid behide a tree and smoked a cigar. I heard the conversation that he was pressing his son to marry my daughter. Every words he said, it makes me feel black and angry. Also, I do not want him to tell my secret. After young McCarthy left, I hit him and he fall. He screams bought his son running back. I have to hide behind the tree but I dropped my coat, so I quickly get it and run away,” John Tuner said.

     So the murderer is clear that John Tuner is the murderer and he die after seven months. The young McCarthy came out from the prison because the few facts which I helped him and made him is not guilty of murder. But the Mystery of Boscombe Pool is still the mystery because I did not give the whole story to the police, so everyone will not know the truth about who is the murder except John Tuner, Watson and I.
