Hattori Heiji, who was lying down, immediately got up and said, "Uncle, I'll go with you, after all, there are detectives who go to the diplomat's house, but it's easy to cause a scandal, and you can pretend to be father and son when you go with me."

"Xiaolan, Zuo Ye, will you two come together?"

Zuo Ye glanced at Hattori Heiji, and just wanted to open his mouth to refuse, but the next second the system came with a prompt.

[Please let Hattori Heiji feel the difference in strength, and you can get 100 reinforcement points by completing it, and the remaining time of the mission - 5:59:59]

Zuo Ye: "......"

Where does the gap in strength come from, this is clearly the gap between the open player and the operator player...... Although the player's operation ceiling in this game is ridiculously high.

"Drop."

At the same moment, Zuo Ye's mobile phone rang, and he took it out to take a look, but it was an email from Gin.

"New mission, go solve a diplomat, act tomorrow, the relevant information is below, take a look first, and I'll give you the number of my teammates later."

Zuo Ye: "......"

Isn't this a coincidence?

"Tsujimura...... Miss, if I'm not mistaken, you just said that your husband is a diplomat?"

Tsujimura Gonge, who had already put on his sunglasses again, stared at Zuo Ye for a few seconds and nodded in confirmation.

"Alright, let's go."

Hearing Zuo Ye's answer, a smile immediately appeared on Hattori Heiji's face, but Mao Liran asked with some resistance, "Forget about the seniors, why should I go?"

"There are many people and many companions, and I always feel that if you go, that guy from Kudo Shinichi might show up too."

As soon as Hattori Heiji's words came out, Maori Lan suddenly stopped squeaking, so Sano and Hattori Heiji and the Maori family trio all followed Tsujimura Gongjiang to a mansion.

It won't be wrong, this location is the residence of the mission target given by Gin.

Zuo Ye looked at the structure of the mansion as if looking at the scenery, although according to his intuition, there would definitely be an accident here today, but no one knew who the accident would be, so just in case, it was better to step on it in advance.

"Madame, you're back."

As soon as I entered the door, I saw a middle-aged man in a suit, who should be a butler.

"Well, where is the lord now?"

Tsujimura nodded and asked about her husband's location.

"The master should be in the study now."

"Okay, I'll bring these friends of the old man over to talk."

And just as Gongjiang Tsujimura was about to go upstairs, a "mom" stopped her, and everyone followed the sound and saw a man and a woman appear.

One of the girls is exactly the same as the photo of the girl named Sachiko Katsuragi given by Kimie Tsujimura at the Maori Detective Agency, and the man on the side is holding her shoulders, thinking that it is Sachiko Katsuki's boyfriend, the son of Kimiko Tsujimura.

"Why are you here?"

After seeing Sachiko Katsuragi, Tsujimura Koe's face obviously became unpleasant.

"I called him."

The man on the side spoke, "I see that my father has always been too willing to see Sachiko, so I forced him to meet him."

Tsujimura snorted coldly, and Sachiko Katsuragi, who was a little embarrassed, changed the subject and said, "Mom, are these your friends?"

"What does this have to do with you?"

The disgust on Tsujimura's face was almost undisguised: "A daughter-in-law who hasn't passed the door yet, I don't think you have any qualifications to be short to my mother!"

After speaking, Tsujimura Gongjiang went upstairs directly, and Zuo Ye and his party could only follow, and when they were about to go upstairs, Zuo Ye clearly heard the man pouting and muttering.

"Cut, it's just a continuation, what's the big deal?"

Zuo Ye's footsteps paused slightly, and then continued to follow.

Continuation?

In other words, Tsujimura Koe is not actually her son

's biological mother?

And it seems that the relationship between the two is not very good, in this case, why does Tsujimura Gongjiang care so much about the affairs of his son and daughter-in-law?

Zuo Ye squinted, originally he saw the appearance of Tsujimura Gongjiang just now, and thought that the victim this time already had eyebrows.

Now it seems that today's things may not be so simple......

As soon as they went up to the second floor, the group bumped into an old man with white hair and a long beard, listening to the communication of Tsuji Village Gongjiang, who should be her father-in-law.

"Ah Xun, he probably fell asleep in the study, I just went to call the door and no one opened it, and I was about to go to the Japanese room."

Ah Xun is the owner of the Tsuji Village family, and he is also the target that Sano just received, the diplomat Tsuji Village Xun, as for the Japanese room, it should be a place similar to a lounge.

Zuo Ye watched the old man of Tsuji Village go downstairs from the sidelines, silently collecting clues and traces that may be related to this eucalyptus.

Before coming to the study, there was a faint sound of music in the room, and Gongjiang Tsujimura knocked on the door and no one answered, so he took out the key and opened the door by himself, and then what came into the eyes of everyone was the study of Nuoda, and the Mediterranean man who was sleeping soundly behind the desk with his chin propped up.

At the first glance of entering the study, Zuo Ye had already sensed a strong sense of disobedience.

While everyone else, including Heiji Hattori and Conan, gathered to the side of the machine that was playing music, Sano's eyes were still fixed on Isao Tsujimura.

"Master, why are you asleep here, wake up."

Tsujimura Gongjiang, who had already walked to Tsujimura's side, pushed the other party, Zuo Ye frowned, feeling that the thick stack of books on the table was a little obstructive to his vision, and he just wanted to change his position to continue observing, but Tsujimura Xun, who was pushed, fell directly headlong.

"Sir!?"

In the exclamation, Conan and the others also quickly focused their attention on Tsujimura Xun.

"It's useless, he's dead, call the police!"

Mori ran to the police with skillful steps, while Zuo Ye looked at his target who had become a victim and fell into deep thought......

So now the question is, the mission objective is gone before the mission starts, will there be a bonus for this mission?

Although so far, because of Conan, the plague god Zuo Ye's mission, I don't know how many people have died, but in each of the previous times, Zuo Ye has more or less made some efforts, and only this time......

Nothing was done, and nothing needed to be done.

Soon, an old acquaintance, Officer Twilight, arrived at the scene again, and when he saw Sano and Mori Kogoro, he showed dead fish eyes: "Two plague ...... My brother is here."

I just complained about the handover of the two before, but now they are going to work together, how much does the family can't think about it?

"Hahaha, Officer Twilight, see you again."

Maori Kogoro licked his face and laughed, and Sano just nodded slightly to say hello.

"So, what's going on?"

Officer Twilight waved his hand wearily and asked about the matter, "Is it murder?"

Mori Kogoro touched his head and smiled, "Well, it's not good, after all, the deceased didn't have any external injuries on his body......

"It's poisoning......

"The deceased's lips are purple, obviously poisoned, and there is a small red dot at the root of the back of the ear, and there is also a silver needle on the ground that is suspected to be a murder weapon, it is very likely that he was pierced by the poison needle behind the ear and died, and judging by the condition of the corpse, the time of death should have been not long ago, probably between half past three and four o'clock."

Before Conan finished speaking, Hattori Heiji had already said a lot of things, causing Officer Twilight to freeze in place: "Are you?"

"I'm a high school detective from Osaka, Heiji Hattori."

Heiji Hattori put his hat back again and introduced himself.

"Hattori Heiji, isn't that ......?"

Officer Twilight reacted suddenly: "The head of the Osaka Prefecture Police Headquarters, the son of Hattori Heizou?"

"Huh?"

Maori Kogoro on the side

They were all a little surprised: "So you kid still has such a background?"

"Now it's more important to have the eucalyptus."

Hattori Heiji said, Officer Twilight and Mori Kogoro glanced at each other, and could only turn to ask about other things: "I see that the windows in this room are well locked, so the only entrance and exit to this study is the door, Mrs. Tsujimura, may I ask how many keys are there to this door?"

"There are two in total, one on me and one on my lord."

"On your lord?"

Officer Twilight quickly pulled out of Tsujimura's pocket, and in the mezzanine pocket of his pants, a key attached to the pendant slipped out.

"This ......"

Seeing that the deceased really had a key in his pocket, Officer Twilight and Conan Hattori Heiji all changed their faces, only Maori Kogoro was still confused: "What's wrong?"

"What's the matter, there are only two keys to the study, one on Mrs. Tsujimura, who has been with us, and the other on the deceased, which means that this case is a secret room murder that cannot be committed!"

Hattori Heiji scolded Maori Kogoro with a solemn face, only Zuo Ye was dripping in his heart, couldn't it be that the murderer quietly matched the third key, or could he open and close the lock with other methods without leaving a trace......

Forget it, Kexue's world is decided by Kexue's detectives.

"What are you still doing in a daze, why don't you hurry up and ask the suspicious guys about their actions between half past three and four?"

And just when Officer Twilight and the others were shocked to find out that this was a secret room murder, Hattori Heiji urged again with dissatisfaction, and Officer Twilight could only quickly arrange work, and then realized that something was wrong a few seconds later.

Even if Hattori Heiji is the son of a big official's family, but Hattori Heizou is not in the same area as himself, why should he listen to a hairy boy shouting?

Officer Twilight glanced at Maori Kogoro, hesitated for less than a second, and leaned over to Zuono's side, muttering in a low voice, "Brother Zuono, you have to give some strength, you must not let outsiders look down on our detectives in Tokyo!"

Zuo Ye blinked his eyes, and Officer Twilight said this as if he was also a detective......

"Ahem, then, Mr. Koike, let's talk about what you're doing between half-past three and four."

Officer Twilight remembered Sano's way of doing it, and quickly began questioning the suspect so that Sano could see the truth more quickly.

After a meal, the situation became clear.

Koike, the housekeeper of the Tsuji Village family, had been chatting with the neighbors at the gate until Tsujimura Koe returned, and then hurried home to greet him.

And Sachiko Katsuki and Takazen Tsujimura, that is, the little couple, came back shortly before four o'clock, and when Koike went to meet Tsujimura Koe, the two went to the study to look for the deceased, but they didn't get a response, so they went downstairs and happened to run into Sano and them.

In the end, it was Tsujimura's father, the old man Toshimitsu Tsujimura, who arrived here after two o'clock, but because he couldn't open the door like the little couple, and Tsujimura Gonge also went out, so he kept watching TV next door to the study.

Judging from these confessions, the most suspicious ones at present should be the little couple and the old man Toshimitsu Tsujimura.

That's what Heiji Hattori should have thought.

Zuo Ye withdrew his gaze from a photo on the bookshelf, and looked at Conan again, this kid's cold seemed to be getting worse and worse, his expression was in a trance, and his steps were fluttering.
