An almost perfect murder

For a few weeks now, Shinichi had been back to his old, much more dear size. After his last case, which was not only very dangerous but also incredibly painful, he had allowed himself a break. After 2 weeks he had recovered from the consequences of the reconversion. But now he was starting to get bored. Of course it was nice to do great things with his girlfriend Ran, but such an enthusiastic and talented detective was just not excited about a criminal case.

One morning Shinichi took a little walk to distract himself. When he turned a corner, he saw his friend Ran talking to her best friend Sonoko. The two of them had discovered him now and he was walking towards them.Ran fell on his neck and kissed him. Then she asked: "What's up Shinichi, you look kind of weird". "Oh nothing," Shinichi replied, knowing that Ran was really glad that she and Shinichi hadn't had any cases recently. "Really nothing? ". "Yes everything is okay". Now Sonoko joined the conversation again: "Hey, you two lovebirds, how about you come to the big ball tonight? The organizer, Mr. Arthur White, an American, has announced that all students from the 1st . High school are cordially invited! ". The reason for this is the opening of his own private clinic, which he wants to advertise to young people in particular. Ran replied enthusiastically: "That would be really great, wouldn't it, Shinichi?" "I wouldn't mind, a little variety can't hurt," said Shinichi, who quietly thought that he would much prefer a new case."Hey Kudo!", Shinichi heard suddenly behind her. When he turned around, Heiji and his friend Toyama Kazuha were standing in front of him. Shinichi already knew Toyama from his time as Conan Edogawa. She had a total crush on Heiji and would do anything for him as he did for her. However, the two would never admit that they loved each other. Shinichi didn’t let this be noticed and asked who the girl was. "My name is Toyama Kazuha and you are sure to be this Shinichi Kudo". "Yes", Shinichi replied with a laugh, "I certainly am. And so you are Heiji`s girlfriend". At the same moment he was pounded in the ribs by Heiji and both of them turned bright red. Ran and Sonoko had to laugh so loudly that one could no longer hear Heiji and Toyama's arguments. After Ran and Sonoko stopped laughing, Shinichi asked why they were back in Tokyo. "Well Toyama wanted to go shopping again and I wanted to visit you again," replied Heiji.Then Ran suddenly said: "You could go to this ball with us on China Street today! I would lend Toyama a dress and Shinichi could lend Heiji a tuxedo." Again Heiji and Toyama blushed and neither of them said anything. Finally, Heiji took heart and asked Toyama if she wanted to go. She immediately agreed, and the five friends arranged to meet at Shinichi's at eight o'clock.

After they had all found something suitable to wear, they let Ran's father Kogoro Mori drive them to China Street. Sonoko wasn't there because she wasn't feeling well. They thanked Kogoro and went into the big building.
After two hours they were all tired of dancing and, except for Toyama, who had gone to the bathroom to freshen up, they were standing with Mr. White, with whom they were talking. Mr. White was a stocky man about 50 years old.His short-cropped hair was already a light gray color. Since it was very loud in the dance hall, they went into an adjoining room. Mr. White was talking about his previous life as a doctor when suddenly the power went out. "Too bad, again" they heard Mr. White say "could you please go to the safety box Mr. Korner?" Mr. Korner, who had been wearing an eye patch since an accident, was Mr. White's personal servant. He often had small vision problems, which Shinichi noticed straight away. "As you wish," Shinichi, Ran and Heiji could still hear. They stopped the door and closed. Suddenly the three heard a strange noise, as if someone were falling over, of course they couldn't see anyone. After three nervous minutes the light came back on. Right in front of Ran, Mr. White was lying in a large pool of blood. She screamed and backed away. Alarmed by the scream, the door was thrown open and several other guests came in.Only Shinichi and Heiji kept a cool head and tried to calm people down. During this time, Toyama came back and shortly afterwards Mr. Korner, who seemed shocked at the death of his master. When people finally calmed down, Shinichi ordered someone to call the police. Of course, this order was carried out immediately.
After the police examined the body on the spot, Inspector Megure informed the friends of the results. "Well, the dead man's name was Arthur White and he was the organizer of this festival. He died from a targeted stab in the back, which was probably carried out with a knife. You testified that the time of death was around 10.25pm, when it was because of The power failure was dark. In addition, a window in this room was open. Who was in this room? ". Heiji replied: "Ran, Shinichi, Mr. White, Mr. Korner his secretary, the two gentlemen over there and me.Mr. Korner left the dark room to turn the electricity on again. "Of course, Megure interrogated the two unknown men immediately. Their names were Hiromi Nagata and Nitsohigu Karzai and were both friends and work colleagues of Mr. White. They were well acquainted with him as they had business dealings with him. During the search of the police files had found out that they were members of a club for close combat weapons of all kinds. When they searched the pockets of the two of them, a bloody knife was found on Mr. Karzai, which turned out to be the murder weapon. There was also a handkerchief in his belongings. in this case the murder seems to have been solved without our help, "said Heiji when the butler was telling Megure that there had been an argument between Mr. Karzai and Mr. White. Something bothered Shinichi. He didn't know exactly what, but he had a bad feeling.So he asked Mr. Korner: “I would like to see the way to the fuse box that you went.” Everyone was surprised, but no one objected, as they had a high opinion of Shinichi. Arriving at the fuse box, Shinichi heard Toyama mutter: "Funny, actually I should have heard him". Of course Shinichi asked what she meant and she explained to him that she had stood in the dark corridor during the power failure, but had not heard Mr. Korner pass by. The fuse box was in a small room with a slightly sloping floor. In front of the fuse box was a wet sponge in a hollow and in one of the lower corners was a metal ball with two strong fishing lines, each with a loop at the end. Shinichi looked up and saw a beam with a small cut directly above the fuse box. The others, except for Heiji, didn't notice anything except for the sponge.The two considered. Everyone was just about to go back when Shinichi said to Heiji: "Now I've got it, the case is solved. But I still have no proof." Heiji was impressed when Shinichi explained everything to him in detail. “If your theory is correct, then there shouldn't be any fingerprints to be found.” Because they couldn't find any further evidence, they asked Inspector Megure to examine the knife for fingerprints. Inspector Megure couldn't figure it out, but out of respect for Shinichi he ordered the investigation to be conducted. The result was just as Shinichi had thought. Since he was now able to convict the murderer, he said to everyone: "I have now finally solved the murder". Everyone looked at him in amazement. "Of course he's solved Shinichi, Mr. Karzai is the murderer, that's obvious," said Megure. To this Heiji replied: “There is a disagreement, Mr. Inspector.” “Exactly,” agreed Shinichi Heiji, “and not Mr. Karzai is the murderer, but Mr. Korner!". This was followed by dead silence." How do you come to that Shinichi? And what kind of disagreement is there? "Asked Inspector Megure, completely flabbergasted." In my opinion, Mr. Karzai stabbed Mr. White during the power cut. Since he could not get rid of the murder weapon, he pushed it in in the hope that he would later be able to make it disappear without being noticed. There weren't any fingerprints on the murder weapon because he wrapped the handkerchief around the handle. "" The disagreement is that Mr. Karzai did not dispose of the handkerchief. Nobody would have noticed if they had thrown away a Tempo. Besides that, when Toyama was waiting in the hallway during the power failure, he did not hear Mr. Korner pass by. If he had passed by, she should have heard him. "Shinichi replied." Now I will convict the real murderer, Mr. Korner, "Shinichi continued." First he set up a very ingenious system in the room with the fuse box, so that the light would go out by itself after a while and turn on again after about five minutes.To do this, he put a sponge in the middle of the small depression in the bottom. Then he placed a block of ice above the hollow and placed the iron ball that I found in this room on top of it. Two fishing lines are attached to the ball, one short and one long. There is a loop at the free ends of the cord. The long cord will become over a beam of the ceiling. Then you put the loop around the toggle switch of the main fuse. The loop of the short cord is lifted vertically upwards from the ball and also placed around the toggle switch of the main fuse. When the block of ice melts, the short cord is first tightened and the weight of the iron ball pulls the toggle switch down, thereby paralyzing the power supply. When the toggle switch is down, the first loop slips off the toggle switch. After about five minutes the rest of the ice block has melted and the ball rolls down through the slightly sloping floor.This will tighten the long fishing line and pull the toggle switch of the
