her.

"Ran, you shouldn't be here.", He said, although Hisamichi had already been taken away.

"Yeah, I just tripped over this box," she replied and pointed to a wooden box.

Conan examined it more closely and was amazed when he found a small-caliber pistol in it.

"Conan's thing is dangerous, leave it where it is.", Asked Ran and Conan followed.

Kogoro accompanied his daughter outside and the two detectives took a closer look around.

"Everything is very strange. In the rooms next to Hisamichi-sans, there are no windows, the perpetrator cannot have climbed either. Then the pistol in the open closet. Did he have it ready to defend himself if necessary?"

Conan agreed that there were a lot of inconsistencies."And then the playing card. Aces were left with the first three victims, I expected that we would find the remaining ace-hearts here, so why a king? I assumed the cards didn't matter, but there has to be a reason why he chose this card of all places. ", he mumbled and Heiji agreed with him.

"The real problem is ... should the perpetrator not have used the window ..."

"... we have a murder in a locked room.", Conan finished the sentence.
Shirokyou - living room of the Takahashis
"I'll summarize again. Mori-san was in the kitchen with the children and Toshino-san. The butler thus has an alibi. Sutetsu-san was with me and Amano-san was guarding the victim. Yuuka-san, Atsushi -san, where were you two? "Yamato wanted to know.

Hisamichi's wife was still shocked but answered.

"In my room, I read. And no, no one can testify to that," she revealed.

Yamato looked at the victim's son.

"I was outside for a bit of a walk. And no, nobody saw me.", He grumbled dissatisfied.

"Hey Inspector! Don't you think that the guy doesn't seem to care much about his father's death?" Kogoro whispered to Yamato.

This ignored him. He began to write down a few things.

Conan and Heiji stood in a corner and discussed.

"Hey, do you have a network here?" Asked the detective from Osaka, but Conan said no.

"So ... there is a computer with an internet connection in the mayor's study," Toshino-san informed them kindly.

The two detectives thanked him and allowed themselves to be taken there. Then they asked to be left alone for a moment.

"Hey Kudo, do you think the same as me?"

Conan had taken a seat in the wide chair and was already looking for the necessary information. Then he found an article.

"Inoue Takato, 29. The police assumed a robbery because they could not find the man's wallet. However, a fisherman was able to secure it in a net a few days later because the river was so strong that it became his Flushed jacket pocket. When you found out about your debts, you declared it a suicide. ", Conan read aloud and then let Heiji take a look at it.

"Does it also say what the guy did for a living?" He wanted to know.

Conan scrolled further down and was surprised to see Inoue's photo in profile.

"Apparently he committed several break-ins and was often in prison. Once a young woman is said to have died in the process. A fight broke out, Inoue threw her away and she fell miserably. he reported.

Heiji started to grin and Conan also understood what was being played.

"I think that would have solved the case," he whispered.

But Conan still hesitated.

"But we don't have any evidence, right?"he asked sharply.

Heiji had to agree with him, there was still a lot to arrange for her.
Shirokyou - property of Takahashi Hisamichi
Everyone had gathered in the living room, even if Inspector Yamato wasn't that convinced of Heiji. Kazuha fared very differently. Her boyfriend had turned his baseball cap into the position that left absolutely no doubt. He had solved the case and she was proud of him.

"Well, we'll listen to your theory. How did the perpetrator manage to hide the trampoline so quickly?", Kogoro wanted to know.

"Trampoline?" Yamato asked puzzled.

Heiji hung her head in resignation.

"Well, listen there was never a trampoline!" The detective clarified.

Kogoro turned his head away, offended.

"And how did the perpetrator get up to the window so far?"

Heiji smiled.

"Not at all, he didn't use the window, but the door.", He revealed.

Yamato stared at him in amazement.

"Nonsense! Amano-san was standing in front of it all the time!", He hairy.

Heiji just nodded.

"To understand the sequence of events, I should start with the motive first. We know that all four people in Abukama-san's house were gambling. An ace card was found on three of them, but a king of hearts in Hisamichi-san's Don't you think that's strange? ", Heiji wanted to know the opinion of the others.

But Kogoro didn't think so.

"Who cares? He will probably have lost the actual card and spontaneously decided on a different one," he explained to himself.

But Heiji just shook his head.

"No, he chose this card on purpose. I think this card should best represent Hisamichi. He was the mayor of the city and the perpetrator wanted to hit him right in the heart. He saw him as the greatest evil among the group."

Yamato cleared his throat.

"Still, that doesn't explain why he didn't choose an ace of hearts."

Heiji had a simple explanation for it.

"Because he has used this card before. In the beginning it wasn't four people, but five, remember? Inoue Takato-san the lonely gambling addict who allegedly committed suicide a month ago."

"Allegedly?" Yuuka-san asked in amazement.

Heiji nodded again.

"In truth, he became the first victim of this serial killer. I discovered this while reading the newspaper article. His personal belongings were no longer with him because the current was just too strong. Assuming the perpetrator had slipped him an ace of hearts before if he pushed it into the river, it would certainly have been lost. "

Kogoro jumped up.

"So ... does the perpetrator not even want to avenge this Inoue? He killed him? If so, why?"

Heiji went on to answer any questions.

"Very simple. Inoue-san was a burglar who wanted to pay off his debts. The more his gambling addiction increased, the bolder he became.Three months ago, a woman died in a burglary allegedly committed by Inoue-san. But nothing could be proven to him. So suppose a bereaved of the woman wanted to take the law into his own hands ... he would have a motive to murder Inoue-san. Just like the people who operated their illegal gambling and were also partly to blame for it. "he explained.

Yamato got up and shouted to Sutetsu to get the murdered woman's data. But he hesitated and looked uncertainly at his superior.

"What is it? Come on!" Yelled Yamato irritably until Heiji put a hand on his shoulder.

"That won't be necessary, Sutetsu-san already knows the name of the victim, doesn't it? Just like us. It was a young name ... Eriko ... Amano-san.", He revealed to those present.

All eyes were on the sergeant major.

"Does that mean ... the old man committed the murder?" Asked Kogoro, puzzled.

Heiji confirmed it to him.

"Yes, Amano-san was the only one who could have carried out the murder. He murdered Hisamichi-san shortly after he entered his room. He covered all traces, opened the window and put the playing card ready. Then he locked and waited a few minutes. He probably reported to Sutetsu-san again shortly before the crime so that he had some kind of alibi. The scream was his own, then he played the shocked man and we all ran to the crime scene. He was the only one with one key owned, it could only have been him. ", Heiji finished with his conclusions.

Amano swallowed and his young colleague looked at him in disbelief.

"That ... isn’t all true, is it?", Sutetsu couldn’t believe it.

Amano slumped his shoulders.

"It doesn't matter anymore whether I confess or not. I made Inoue's murder look like an accident or suicide so that it wouldn't lead back to me. Unfortunately, the connection between the victims is clear evidence of my guilt," he admitted to.

"But ... why did you do that?" Asked Ran.

Amano sighed.

"Eriko was my beloved daughter. She was all I had in terms of family. And this bastard just got away with it! I just couldn't help but hold him and his cronies accountable!"

"Shit!" Someone suddenly shouted and everyone assigned the voice to Atsushi-san.

"What the ..." Kazuha stammered.

"He has a gun!", Sutetsu warned now.

Conan recognized her, it was the one who had been in Hisamichi's room.

"Family, yes? To stab my father like that, even though he had his faults ... why do you think you are better?"

"Atsushi, please don't do that!" Asked his mother, but Heiji calmed her down.

"It's okay, there are no bullets in the gun. Conan-kun and I removed them because we feared Atsushi-san might want to use them."he revealed.

Kogoro looked surprised.

"But ... didn't he hate his father?"

Heiji wanted to answer, but Conan got ahead of him.

"It should at least make it appear. He and his father didn't get along, but that didn't mean he hadn't loved him. It was on his face when we mentioned that Hisamichi-san might be the next victim. He looked very worried and compassionate, "he revealed.

Atsushi dropped the pistol and hit the wall with his fist.

"It's not me. I'm no better than Inoue. But if you really wanted to shoot me, then you will certainly understand my actions. The hatred overcame me and I could no longer defend myself and find the right way. I am old and." didn't have the strength anymore. But you are still young. I don't want you to forgive me, just that you don't blame yourself and let yourself be eaten away by hatred. ", Amano persuaded the victim's son.

Atsushi turned his head away and ran away.

Yuuka Takahashi ran after him, everyone present decided to leave them alone for the time being.

Then Inspector
