"You mean someone put this thing here after the fact?" Conan said as he took the golf ball in his hand, sniffed it with his nose, and said, "But there is indeed a pungent smell of black fire and medicine in it, and it also exudes heat." ”

Yamamoto Yoshitsuru shook his head and said, "I don't know about this, I'm just asking." ”

After hearing this, Conan said thoughtfully: "Maybe it's a coincidence, after the bomb exploded, the strong force exploded the golf ball, and then left such a fragment behind. ”

"Maybe!" Yoshitsuru Yamamoto nodded, but he didn't dwell on this issue.

Looking at the two people who were squatting over there and talking, Mao Liran walked to Yumi Miyamoto's side and greeted him with a smile: "Miss Miyamoto, hello!" ”

"Hello, Miss Maori!" Yumi Miyamoto smiled and nodded.

Mao Lilan asked casually, "Miss Miyamoto, do you and Yamamoto often come here to practice playing?" ”

"It's not very often!" Although I don't know why the other party asked this, Miyamoto Yumi still smiled and said, "We only started playing golf here recently, but recently, we have been here a lot." ”

"Oh, I see!" Maoliran nodded and said nothing more. Do you come all the time? This is an opportunity.

Glancing at Yoshitsuru Yamamoto, Yumi Miyamoto suddenly asked, "Miss Maori, are you familiar with Yamamoto?" ”

"Pretty familiar!" Mao Lilan was stunned for a moment, and then replied: "He is learning from my father how to become a detective, so he lives in our house temporarily, so we know each other well." ”

"Do you live together?!" Yumi Miyamoto looked up and down at Mao Lilan in front of her when she heard this, dressed in a high school student uniform, without any makeup on her face, with long black shawl hair, from her body, she seemed to be able to feel the breath of youth. Yamamoto, is this guy really trying to learn how to become a detective? Or was he just trying to get close to the girl in front of him?

Seeing that the other party had been staring at him silently, the look of thought in his eyes made Mao Lilan very uncomfortable, so he couldn't help but call: "Miss Miyamoto.. Miss Miyamoto...."

"Ah?.. Oh! Yumi Miyamoto, who was awakened, smiled, although she had an idea in her heart, she said on the surface: "I'm sorry, I thought of something just now, but I was in a trance." ”

"Oh!" Mao Lilan responded, thinking of the relationship between the other party and Yamamoto's guy, but he didn't know what to say for a while, so he had to be silent.

Looking at Mao Lilan, who didn't speak, Yumi Miyamoto first glanced at Yoshitsuru Yamamoto, and then withdrew her gaze, silently thinking about her thoughts.

Patting Conan on the shoulder, Yoshitsuru Yamamoto got up and said, "Let's go, come with me." He said and walked towards the net.

"What are you going to do there?" Conan asked, and followed.

Yoshizuru Yamamoto said as he walked: "When the explosion just now, I heard a 'clang' sound, and I thought it should be a golf ball hitting the iron on this side." If you look closely, you might find something. ”

"Oh?" Turning his head to look at Yoshitsuru Yamamoto, Conan said in surprise, "Your ears are very good at hearing, you can hear everything." ”

"It's okay, not to mention that the sound itself came after the explosion." Yoshizuru Yamamoto said and walked in the direction that the spiritual sense sensed, there should be a harvest there.

"Yamamoto, it seems that you really guessed correctly." Looking at a black ball on the grass in front of him, Conan took out a white handkerchief from his pocket and picked it up with a handkerchief.

"That's it!" Yoshitsuru Yamamoto nodded, he saw the black ball no later than Conan, but he knew that he would pick it up, so he didn't do it.

"The smell of black gunpowder!" Sniffing the black ball in his hand a few times, Conan said to Yoshitsuru Yamamoto: "It seems that this ball should have been hit by the deceased, otherwise there is no reason why the ball will be black." ”

Yoshizuru Yamamoto nodded and said, "That means that the ball before was not left by the explosion at all, as I guessed, just to mislead the police." ”

"You're right, it seems that the murderer is one of those three people." Looking at the direction where the body was, Conan said: "Since the bomb was not placed in the golf ball, and the murderer left the so-called 'golf ball', that is to say, in fact, the explosion was related to playing golf, and it was not the golf ball that exploded, but the golf club." ”

"You should be right." Yamamoto Yoshitsuru listened, nodded in agreement, and said, "As long as you know who gave that golf club to the deceased?" Who was saving it before that? Knowing these two points, I think the murderer will be caught. ”

"Hmm!" Conan nodded and said, "Now wait until the police arrive, and then the police will interrogate." As he spoke, he handed the black golf ball to Yoshitsuru Yamamoto and said, "Put this thing here, and then you can reason about it." ”

Looking at the golf ball in Conan's hand, Yoshitsuru Yamamoto wrapped it in a white handkerchief and walked towards Mori Kogoro. "I'd better leave it to the Maori master!"

"It's up to you!" Conan didn't care about following behind.

Looking at Maori Kogoro, who didn't know what he was thinking, Yamamoto Yoshitsuru directly spread out the golf ball in his hand and said, "Maori master, I found this on the other side of the course." ”

"Huh?" Mori Kogoro, who was awakened, took the golf ball wrapped in a white handkerchief, sniffed it, and said in surprise: "This is the smell of black gunpowder, does this thing have anything to do with the death of the deceased?!" ”

Yoshitsuru Yamamoto didn't immediately say his and Conan's reasoning, but said, "The residual smell of gunpowder on it indicates that it is related to the explosion, so I will bring it to Master Mori to show you." ”

"You're doing a good job, this thing must have something to do with the explosion, I'll tell them when the police come in a while." Mori Kogoro nodded approvingly, and then brooded back into thought.

Looking at Maori Kogoro, who was thinking again, Yamamoto Yoshitsuru shrugged helplessly. I thought that he would continue to ask, or reason, then he could naturally and slowly tell the reasoning, but when he thought that things changed unexpectedly, Mori Kogoro didn't mean to speak at all. In this case, he has no choice but to take one step at a time.

Twenty minutes later, as the alarm bell rang, several police officers walked in, led by an old acquaintance, Officer Twilight Thirteen.

The two sides first said hello, and then Mori Kogoro briefly explained the matter, and after Twilight 13 learned the basic situation, he asked his men to call the injured two people and the boss and his wife, and then briefly questioned the middle-aged man with glasses who was at the scene.

After Twilight Thirteen's questioning, Yoshitsuru Yamamoto, who was on the side, learned the basic information of the four people, including the deceased. These four people are colleagues from the same company and the same department, and they came here to play because the company is relatively close to here. Among them, the head of the company's product development department, who is about to be promoted to the manager of the New York branch in the United States, is already dead, and the one who was questioned is Minoru Yasui, the director of the development department, Tatsuya Okubo, the director of the development department, who is seriously injured, and the rest is Minami Tomoshi, an ordinary employee.

As soon as he finished questioning Minoru Yasui, the police officers who were assigned to go out walked in with the boss and his wife, Tatsuya Okubo and Minami Tomoshi. Among them, Tatsu Okubo was also seriously injured, his right hand was supported by a gauze bandage, and his head was also tied with several bandages.

Just as Twilight Thirteen was about to question the new recruits, the forensic officer walked over and said, "Report to the officer, after inspection, black powder was used in this case." As he spoke, he pointed his finger to the side and said, "Also, would you like to ask the police officer to come here?" ”

After listening to the forensic staff's words, Twilight Thirteen, Mori Kogoro, Yamamoto Yoshizuru, and Conan followed him to the side where the body was still parked.

"These are the pieces of long-distance golf clubs." The forensic officer first pointed to the debris near a sign with the letter C, then pointed to the debris near a sign with the letter D, and said, "These are the pieces of the golf ball." ”

"And this!" As he spoke, the forensic officer picked up an item from the side of the B sign, spread it out with his hand, and placed it in front of Officer Twilight's eyes.

Looking at the golf ball fragment in the forensic officer's hand, Twilight Thirteen asked suspiciously, "What is this?" ”

The forensic officer replied, "We think it's a core tube, which means ...."

Before the forensic staff could finish speaking, Mori Kogoro took over and said, "The bomb was originally placed in the golf ball, and the moment you hit it with a club, the bomb exploded due to a strong impact. ”

"But that's not right!" Mori Kogoro said as he spread out his left hand to reveal the black golf ball in it, "This golf ball was found by Yamamoto on the other side of the course, and it should have been played by the deceased Mr. Tachibana." According to my reasoning, the bomb should have been installed in a golf club, how could there be an extra fragment? ”

"That's it!" Looking at the golf ball in Mori Kogoro's hand, Twilight 13 put on his gloves, took the golf ball fragment in the hand of the forensic officer, looked at it, and said to the boss on the side, "This gentleman, do you have a red line on each of the golf balls here?" ”

"No, it's all green lines." The boss said and looked around, then pointed to the side of the court and said, "It's like a ball there." ”

Looking in the direction the boss pointed, Twilight 13 nodded, "I see, it's indeed green, and there's only one green line." ”

"In that case, this thing should have been deliberately left behind by the murderer." Mori Kogoro said and looked at Minoru Yasui, Tatsuya Okubo and Minami Tomoshi: "In other words, the murderer should be one of the three of you." ”
