When Hattori Heiji heard that he was described as a "child", he was so angry that he walked up to him and yelled.

"Hey! Auntie!"

"If you keep talking nonsense, I won't forgive you!"

This sound frightened the housekeeper's body, and she quickly defended herself, "I didn't lie to you!"

"When I came here this morning, Mr. Kudo had already passed away!"

At this moment, the housekeeper finally couldn't stand the pressure and admitted everything.

It turned out that she came over to clean up at her usual time today, and as soon as she entered the door, she heard the phone at home ringing non-stop.

Since Kudo Shinichi doesn't leave his room recently, she usually answers the phone at home.

But when he picked up the phone, a voice that sounded like a voice changer said that Kudo had died in his room.

The housekeeper came to the bedroom and found that the bedroom door had been sealed with tape.

When she tore off the outer tape and opened the bedroom door, Kudo Shinichi was dead inside, with a photo of her son next to his body.

The voice on the phone threatened that if he didn't do what he said, his son would suffer the same fate.

At this point, tears welled up in the corners of the housekeeper's eyes, and big tears flowed down.

Qin Zhibo saw that her expression didn't look like acting, so he continued to ask: "What did that person ask you to do for him?"

The housekeeper said while sobbing: "He asked me to disguise Mr. Kudo as if he was still alive and wait for a 'kid' who called himself a detective to come over."

"Then let me tell the 'child' that Mr. Kudo is asleep and ask him to wait in the living room for a while."

"During this period, I used the excuse of going out to buy groceries, but actually brought the coal stove into the room, sealed the door with tape, and hid myself behind the door."

"After half an hour, I will activate the alarm in the room and ask the 'child' to come from the living room and knock on the door. When the time is right, I will stand up from behind..."

After the housekeeper's description, the three smart people immediately understood the real murderer's entire plan.

The real murderer wanted to make the room look like a murder scene where Kudo Shinichi committed suicide by burning charcoal.

Does that mean that Kudo Shinichi actually died of carbon monoxide poisoning?

"Where is the coal-burning stove you mentioned?"

"It was placed in the room at first, but I took it to the storage room..."

With that said, the housekeeper turned around and opened the storage room opposite the bedroom door, and took out a coal stove, tape and a photo of her son.

Qin Zhibo motioned for her to put them on the ground, and then continued to ask: "Did you place these things in Mr. Kudo's bedroom after you entered the room this morning?"

"Yes..." The housekeeper nodded tremblingly.

Conan and Hattori Heiji walked to the door of the room and glanced at the evidence on the ground.

The tape is unopened and has been used for some time.

There is still burned briquettes in the coal-burning stove that is larger than a basketball. It has almost cooled down and can be taken out directly with your hands.

Looking at the briquettes, Conan and Hattori Heiji looked at each other.

Although this plan disguised as suicide looks good, it actually has many loopholes.

First of all, the burning time of only half an hour is not enough for a coal-burning stove of this size to emit carbon monoxide that fills the entire room.

Secondly, the plan provided by the so-called "murderer" did not mention wearing gloves. He probably wanted to have the housekeeper come in to help remove the tape and carry the coal stove after the body was found.

However, based on Hattori Heiji's character, once it is confirmed that the deceased is hopeless, he will immediately seal off the scene and not allow anyone to enter.

In the end, the murderer was unlucky. He met Qin Zhibo, who had terrifying powers of observation. He was seen dead or alive at a glance, and there was no chance for his trick to be used.

At this time, Qin Zhibo also retracted his finger from the door frame.

As the housekeeper said, there is a sticky feeling on the door frame, and the remaining glue stains can be seen under side light.

Although it cannot be ruled out that the housekeeper is using a trick, various signs indicate that Qin Zhibo feels that the real culprit must be someone else.

Qin Zhibo turned to look at the housekeeper again, "Did the person who called you say anything else?"

The housekeeper was startled for a moment, and after recalling it for a few seconds, she answered tremblingly.

"He claims to be..."

"The wraith of the devil dog..."

…

The police who received the call quickly dispatched the police.

They were at the murder scene again, and there were three familiar people there. Officer Memu had a helpless expression on his face.

He was too lazy to complain and went straight to the topic.

Under the introduction of Qin Zhibo and others, Mu Mu had a rough understanding of the general history of the case.

"In other words, the person on the phone just left the name 'The Wraith of the Demonic Dog' and hung up the phone?" Mumu asked.

"Hmm..." The housekeeper nodded.

Standing next to Megure, Wataru Takagi held a notebook and asked, "Did the deceased Mr. Kudo have any grudge against anyone?"

"Is such that……"

Just as the housekeeper was about to answer, Hattori Heiji, who was standing next to her, interrupted her.

"Actually, the victim was originally the adopted son of Tsunei Inubushi, the president of the Inubushi Group who passed away five years ago."

"But recently he has been scared to death because it seems that a bad person has sneaked into the Inubushi family and is using the 'curse of the devil dog' to make the Inubushi family extinct."

"I think this is probably why the prisoner calls himself the 'Wraith of the Demonic Dog'..."

The word "prisoner" that Hattori Heiji said showed that he already agreed with the housekeeper's previous statement.

"Devil, devil dog?"

After listening to Hattori Heiji's summary, Megure and Takagi Wataru raised their necks at the same time.

Mu Mu complained, "It sounds a bit like a mystery novel..."

Takagi Wataru on the side immediately reminded, "There seems to be a similar story in Sherlock Holmes..."

Sherlock Holmes?

This strange foreign name made Megu's eyes even more confused, and he could only guess one that was close to "dog".

"Is it the Inugami family?"

Takagi: "..."

Not far away, a senior Fu fan wearing glasses also expressed his speechlessness.

When Mu Mu saw that he had not guessed correctly, he could only cough twice and awkwardly change the subject.

"Ahem..."

"But then again, why is this room so strange? Why isn't there even a single piece of furniture?"

This time it was the housekeeper's turn to explain again, repeating all the requests that Kudo Shinichi had made during his lifetime.

After hearing these requests, Mu Mu showed a confused expression, "Even if the deceased had expected that someone was going to kill him, he wouldn't have gone to such an extent, right?"

Takagi also nodded and agreed: "It's understandable that visitors are prohibited from bringing things into the room, but this special room..."

Under the illumination of a light bulb on the ceiling, Mu Mu looked around the room.

Not only was there no furniture in the room, but the strangest thing was that all the corners, gaps, and edges of the walls were plastered into arcs.

Even the windows are completely sealed and airtight.

The whole room had an indescribably weird feeling.

It's better to call it a cage than a shelter.

It's just that Kudo Shinichi built a cage and locked himself in it.

At this moment, Mu Mu saw Qin Zhibo standing alone in the corner. As if he saw the answer to the problem, he immediately stepped forward and asked.

"Brother Qin, what do you think of this case?"

Qin Zhibo, who was staring at the corner, turned his head and analyzed: "Judging from the current situation, the possibility that the murderer is someone related to the Inufushi family is very high."

"If you want to know the identity of the real murderer, you have to go to Inubushi's house..."

"The Inubushi family?" Megure was stunned and asked, "Where is the Inubushi family in Tokyo?"

Hattori Heiji on the other side introduced: "The Inubushi family is not in Tokyo, but in Gunma County. It is said to be in a place called 'Inubushi Castle'."

"Gunma County..."

Megure sighed deeply. If he wanted to handle cases across jurisdictions, he would have to apply to cooperate with the Gunma County police.

However, he heard that there was a police department in Gunma County that was very skilled in handling murder cases. The police officers from other places who had cooperated with it all said that it was a headache.

I hope it's not that person...

Hattori Heiji also saw Megure's dilemma, so he offered to let their detectives investigate first, so as not to alert the police.
To be continued...
