"Madame, you're back. Pen & Fun & Pavilion www.biquge.info"

"Where's the master?"

"I think the master should be in the study."

"Who are these guests?"

The housekeeper Fumio Koike looked at Kogoro and the others who came back with his wife and asked.

"Mom! You're back. ”

At this moment, a very beautiful young woman walked out and greeted her respectfully.

"How did you come to this place!"

Mrs. Tsujimura asked very dissatisfied.

"I asked her to come, and I saw that my father had always been reluctant to meet Sachiko, so I forced my father to agree. Looks like Dad hasn't left the study since just now. ”

A young man stepped out and put his arm around Sachiko's shoulders and said.

"Ahh That's right. Mother. Are these people your friends? ”

Sachiko looked at Kogoro curiously and asked curiously.

"Doesn't it have anything to do with you? Also, you're not qualified to call me mom right now! ”

Mrs. Tsujimura reprimanded with great dissatisfaction.

"Yes. I'm sorry. ”

Sachiko, who was reprimanded, bowed her head in frustration and apologized.

Yi Bin stood at the back, put his left hand behind him and secretly summoned the World Crystal. Observe the inside of the house.

It was found that there were two people in the room with a more pronounced red glow on their bodies. Both targets are on the second floor, one is in the study, and the red mangs are very obvious. One is in the aisle, and the red rays are darker.

"Come with me."

Mrs. Tsujimura led everyone to the study on the second floor.

As soon as I walked up the stairs, I saw an old man with a mustache walking over.

"Dad, you haven't gone out yet."

Seeing the old man, Mrs. Tsujimura asked.

"What are you talking about? I'm going to show you this fish I caught. ”

"Well, isn't this fish big?"

The old man took out a piece of paper with a picture of a fish from behind him and placed it in front of him.

"Alas. It's quite big, indeed. I'll be there right away, so please go to the Japanese-style room and wait for me. ”

Mrs. Tsujimura looked at the old man and said helplessly.

Then the old man staggered down the stairs. And when the old man walked down the last step, he suddenly stepped on the empty foot, and then fell to the ground: "Oops! ”

"Grandpa!"

Seeing the old man fall, Takazen Tsujimura and Sachiko Katsuragi hurriedly ran to the old man's side.

Kogoro and the others also walked down the stairs.

"It's okay, it's okay. Leemitsu, help me to the Japanese-style room. ”

The old man waved his hand to everyone indifferently, and was helped by Tsujimura Toshimitsu to the Japanese-style room to rest.

"Then, Mr. Maori, let's go to the study and meet our master."

Mrs. Tsujimura saw that there was nothing wrong with her father-in-law, so she turned to Maori and said.

Mrs. Tsujimura came to the study and knocked on the door, but there was no response. So he took out the key and opened the door to the study.

When I opened the door, I immediately heard the sound of opera in the study. The Tsujimura diplomat, on the other hand, leaned back in his chair with his hands hanging at his sides. There is a very distinct purple-cyan palm print on the neck.

"Husband! Wake up. Husband. ”

Mrs. Tsujimura looked nervous and ran to the side of the Tsujimura diplomat and shouted.

Seeing this, everyone rushed to the side of the diplomat from Tsuji Village to check on his condition.

"It's useless, he's dead."

Hattori touched the arteries of the diplomat in Tsuji Village, and then said solemnly.

"Xiaolan! Contact the police! ”

Hearing the news, Maori Kogoro hurriedly ordered Xiaolan to call the police.

"Uh. Be! ”

Hearing the instructions, Xiaolan hurriedly ran out to contact the police.

Conan and Hattori inspect entities. The corpse's face was swollen, his face became bruised, his lips and nails became cyanotic, and there were blood spots on the conjunctiva of the eyes. Coupled with the purple-black palm prints on the deceased's neck, it indicates that the deceased was strangled to death.

More than ten minutes later, Officer Twilight and his men arrived at the home of the diplomat in Tsuji Village.

"The deceased, Isao Tsujimura, is 54 years old, and there happened to be a detective at the scene where the body was found."

Officer Twilight looked at Mori Kogoro speechlessly.

"That's right, Officer Twilight. It's my Mori Kogoro! ”

Kogoro said proudly.

"So, is this a murder?"

Twilight looked at Mori Kogoro as if she were looking at a fool.

"That's right, judging from the scene, the deceased should have been choked by the neck with his hands and strangled to death."

"The deceased's lips and nails were cyanotic, his face was swollen and purple, and there were spots of blood on the conjunctiva of his eyes, all of which proved that the deceased had died of asphyxiation. Coupled with the obvious purple palm print on the deceased's neck, it is even more certain that the deceased was strangled to death. ”

Mori Kogoro listed the symptoms of death of the deceased one by one.

"That's right, and judging from the deceased's body temperature, and the fact that there is no postmortem stiffness on the deceased's body, and the absence of corpse spots, he must have been strangled alive with one hand within 30 minutes before we entered the study."

"Moreover, judging from the fact that the doors and windows at the murder scene are locked from the inside, and there are no traces of violent damage, it is very likely that the murderer is the person who has the key to the house."

Hattori explained his reasoning one by one.

"Maori, who the hell is this young man?"

Officer Twilight heard Hattori's reasoning and asked Mori angrily.

"His name is Heiji Hattori, and he's an arrogant teenage detective."

Mori Kogoro explained very reluctantly.

"Oh? Heiji Hattori! It turned out to be you. Are you the son of Heizou Hattori, the current commissioner of the Osaka Police Station, who is in high school? ”

Officer Twilight turned to Hattori and asked in surprise.

Xiaolan looked at Hattori who had just finished reasoning suspiciously: Strange, this person called Hattori seems to be a new one.

"Well, it's true, all the windows in the study are locked from the inside, and it's impossible to get in and out from the outside. In this case, the only entrance and exit is the door. So, the most likely thing to give now is to the person in your house who has the key to this room. ”

"Mrs. Tsujimura, how many keys do you have in this room?"

Officer Twilight walked up to Mrs. Tsujimura and looked up at her.

"No, no, there are only two keys in this room, one is the one in my hand and the other is on my husband."

Mrs. Tsujimura said, taking out a key from her bag.

"Oh? On your husband? ”

Officer Twilight grabbed the key point in Mrs. Tsujimura's words and hurriedly asked.

"That's right, I'm used to keeping my keys in my pants pocket."

Mrs. Tsujimura explained.

"Then me. I'll take a look. ”

Officer Twilight examines the deceased's pants pocket. It was found that the key was actually in the inner layer of the double pocket of the deceased's pants.

Seeing this, Twilight, Hattori, and Conan all looked in amazement at the key that had fallen from the double pockets of their pants.

Yibin, on the other hand, just leaned against the door frame and watched quietly.

"How is this possible!"

Twilight shouted in surprise.

"Uh, what's wrong?"

Mori Kogoro looked dazed.

"Don't you understand? When we came, the door of this study was obviously locked, that is, the murderer only left after committing the crime, and if there were only two in this study, one had been on the body of the lady who was with us, and the other had been in the double pocket of the victim's pants. ”

"This makes up the perfect impossible crime! It's a backroom murder! ”

Hattori turned to Mori Kogoro and said solemnly.
