"The deceased's name was Naoya Saijo, a full-time diver at the Reiko Sports Club. Judging by the stiffness of the body, we judged that he died between eight and nine o'clock tonight. ”

"The cause of death is drowning!" "Oh yes!" Looking at the little foam in the deceased's mouth, there was still faint bleeding in the ear holes, and these evidences made Kogoro make a judgment directly.

"But then again, it's ironic that he, a professional diver, would be drowned!" "That's why I failed to dive and hit my head on the diving platform!"

Kogoro glanced at the corpse and immediately found a mark on Naoya Saijo's forehead, coupled with the condition in the afternoon, he should have died unfortunately.

But he always felt that things were a little strange, with Conan present, would it be so simple? The bad feeling in his heart made him look at the corpse for a while, and then he found out what the problem was, earplugs and headscarves.

"Officer Twilight! Was he not wearing earplugs when the deceased was found? "Ah, we've put away the earbuds." "Is that so! Did you find any other clues? ”

"We just found a witness from the building opposite. According to him, after eight o'clock, he looked out the window and saw people practicing diving. ”

"Then did he see clearly, that person was Naoya Saijo at that time?" "Ah, that's not it! Māori brother, do you mean, someone deliberately pretended to be him and dived? Unlikely, right!? ”

"But it's impossible, just ask again." Kogoro stared at him, whether he could lock down any evidence, it was up to him to see if he was on this trip, and then they went to the man's house.

The building was just across the plunge pool, and the living room was facing this side. The witness was an old man in a wheelchair, who spoke to him and saw a sketch he had made based on what he had seen at the time.

After that, Kogoro knew who the murderer was, and the pointing evidence was very obvious. And his tools for committing the crime should still be in the club, from which decisive evidence can definitely be found.

According to the old man, every day after dinner, that is, around a quarter past eight o'clock, he would watch the swimming pool on his balcony for a while, and today he happened to see someone diving.

At that time, the lights were off in the swimming room, and the scene when people jumped up was very beautiful, not only with a beautiful posture, but also with a faint glimmer in the moonlight, so he couldn't help but draw it.

The painting is a stick figure sketch of a window, a jumping platform, a full moon, and a graceful diver, forming a wonderful scene, and the pointing evidence is on the man's ear.

Kogoro had the answer in his heart, but he still confirmed it with the old man. "Can I ask you two more questions?" "Good! You ask! As long as I can help you, it's no problem to ask as many as you want! ”

"That's good! Can you confirm that the painting is exactly what you saw it at the time, and that it has not been altered by you? Kogoro stared at the old man with burning eyes, as if trying to see if what he was about to say was true.

"Well, I just drew it according to the scene at that time, and I definitely didn't add anything to it!" "So the reflection, or the place where the light shines, is it the side of his head?"

This time the old man thought for a moment, and did not choose to answer directly, but then he gave a positive answer, judging from his expression and micro-movements, he did not give a reluctant answer, but was very sure of this.

"Good! So when you look at the pool, do you see someone diving, or do you see someone after a while? "Well, I didn't see that man until seven or eight minutes later!"

"So do you remember how long the man jumped?" "How long?! He only skipped it once! "Once! I see, thank you very much for your help, this time thanks to you! ”

"Really? I'm glad I can help you, a great detective! The old man smiled, clearly pleased with Kogoro's thanks.

After taking a few pictures of the painting, Kogoro said goodbye to the old man and returned to the Reiko Sports Club with Officer Twilight and the others, and gathered the relevant personnel.

"Officer Twilight! Did you come to me with a result? After being brought in by the police, Reiko Saeki opened her mouth and asked directly. But the person who answered her was Kogoro.

"That's right, I already know who the killer is!" "Murderer?! Could it be that Saijo was killed by someone? Several relevant personnel of the club immediately shouted in surprise.

"Yes, he was deliberately killed, one of you, Sai, who disguised himself as an accident after killing him." "What!? Is it one of us!? ”

"Yes, he drowned Naoya Saijo after he stunned him with anesthetics. Then he was given earplugs, which is why he was bleeding slightly from both ears. ”

"Then the murderer thought that he died in an accident while diving, so he deliberately let his head hit somewhere, and in order to be able to disguise it more likely, he also put a hood on him."

"But maybe it's because I've gotten used to wearing a headgear before exercising, so I didn't think about it at all, and divers don't need to wear a headgear."

Listening to Kogoro say this, several people who were or are now divers all understood who Kogoro was talking about, and they all set their eyes on Kijima Hisashi.

But he himself was calm and did not seem to be worried that his guilt would be proven. "He must have heard about the old man in the building opposite."

"Knowing that he will be at a fixed time every day, looking at the pool. deliberately dived to let him see, as Naoya Saijo, it was supplementary evidence that there was an accident during the dive. ”

Like Kijima, Kogoro is also very calm, especially since he has just received a hint from Officer Twilight that those things have been found, even if they haven't been identified yet, they are enough.

But he didn't expect that the old man still had the habit of painting. Yes, he faithfully drew the scene at that time. As he spoke, Kogoro took out his mobile phone and showed the photo of the sketch in front of everyone.

Because they knew who the murderer Kogoro was talking about, everyone instantly discovered what Kogoro wanted to say, that is, the earrings that reflected the light of Kijima Hisashi in the moonlight at that time.

At the same time as seeing the photo, Kijima changed his previous calmness, his face became extremely ugly, his lips suddenly squirmed, and he was about to say something, but was stopped by Kogoro's movements.

I saw Kogoro beckoning to a police officer on the side, and took two evidence bags from his hands, which contained a bottle and a towel respectively, which were the tools of the crime when he committed the crime.
