"It's game over!"

As Hattori Heiji fell asleep due to the effect of the anesthetic needle, Conan immediately took out a bow-tie type voice changer, and by adjusting the knob of the voice changer, his voice became Hattori Heiji's voice, and then Conan hid behind the door and used Hattori Heiji's voice to imitate Hattori Heiji's Osaka accent as much as possible and said-

"I already know exactly who the murderer is! And what methods did the murderer use to commit this incident!"

"Huh?"

Suddenly, everyone present, who had just been surprised to learn that Toshiaki Fujisawa and Ayako Oki had known the owner Hiroyuki Kanaya for a long time, suddenly heard Hattori's words, and their expressions couldn't help but look even more surprised, and they turned their heads to look at Hattori Heiji, who was leaning on the door at this time.

"That's right, the first person who killed the owner of the inn, Mr. Kanaya, and made him fall off a cliff in a car, and the culprits who tried to use the volatile gasoline in the garage to harm Miss Ohki and Mr. Fujisawa......

As he said this, Conan at the same time held up Hattori's drooping right hand from behind the door, and asked Hattori's hand to point at someone in the room—

"That's you!"

Ling Ran, Hattori's voice said categorically.

"Huh? Me?"

However, looking in the direction that Hattori's Heiji finger was pointing, standing in front of everyone, the candidate who was pointed by the finger, Mori Kogoro looked surprised, pointed at himself with his finger, and asked blankly.

At the same time, everyone present was also shocked.

In this regard, after leaning out from behind the door a little and looking at the situation in the room, Conan was a little helpless, and continued to explain in Hattori's voice:

"Wrong! I'm referring to the uncle behind him, who is breaking out in a cold sweat at this time...... Mr. Kento Toba! The murderer is you!"

As soon as these words came out, Toye Yanren couldn't help but be stunned, and he was stunned on the spot for a while.

At the same time, Ayako Oki on the side was slightly disappointed after hearing Hattori's voice say the result, and finally lowered her head helplessly and sighed-

"Wait, wait!"

However, when everyone's eyes turned their attention to Toba Kento in shock because of Hattori's words, Toba Kento immediately retorted in a panic:

"I stayed with you for a few hours before the shopkeeper drove the car! Aren't you here too? Tell me what I can do to kill the shopkeeper while staying with you!"

"Hmph—"

In this regard, just after Kento Toba said this, Kogoro on the side couldn't help but laugh proudly, and then slowly walked up to Hattori Heiji, as if he couldn't bear it anymore, and punched Hattori Heiji in the head-

"Daddy!"

Regarding Kogoro's behavior of punching Hattori Heiji's head, Xiaolan felt that this was very bad, so she couldn't help but advise.

And noticing the strength of Kogoro's punch just now, Conan, who was hiding behind the door, couldn't help but panic-

"Oops! It's not going to wake him up, is it......

But Kogoro was still very displeased, staring at Hattori Heiji's side, venting his anger and saying:

"That's right! You idiot! Look down on people less! Why do you speak in such a weird Kansai accent! When the shopkeeper started the car, weren't you here with Toba? Tell me how he is going to get the car to start!"

"yes, it doesn't seem possible."

However, seeing that after being punched by Kogoro, Hattori Heiji did not wake up because of this, so Conan continued to say in his voice:

"However, if you take advantage of the stiffness after death and the performance of the car, then it is possible!"

As he spoke, Conan paused for a moment, and then told the core trick of the murder of the shopkeeper Hiroyuki Kanaya-

"Here's the trick, put the store manager, who had been dead for a whole day, in the driver's seat and put him on the brakes. After half a day, when the corpse begins to stiffen, so that

Even if the engine of the car is on and the gear is switched to D gear, the car will not move due to the brakes. Then, as long as you open the garage before eating, slowly follow everyone in the house and wait for the corpse to soften, and the foot on the brake will be released, and the car will naturally start!"

"Hahahaha!"

But for such an inference, Kogoro immediately laughed:

"You kid, don't pretend to understand if you don't understand! Stiff corpses don't start to soften until 40 hours after death! If, as you said, the shopkeeper was killed early yesterday, then it was only more than 20 hours, and there is not enough time!"

"But what if the temperature of the environment is higher?"

As soon as Kogoro's words fell, Hattori Heiji's voice immediately gave an explanation.

"Huh?"

Hearing this, Kogoro was stunned for a moment.

"If the temperature around the corpse reaches 35 degrees Celsius, the rate of stiffness and softening will increase, and it will start to soften in about 24 to 30 hours."

Conan smirked and reasoned in Hattori's voice:

"The shopkeeper disappeared after 10 o'clock at night, and if he was killed immediately at that time, the car started around 3:30 this morning, about 29 hours later, doesn't the time coincide?

"And at that time, didn't we also hear the sound of blowing wind coming from the car? It wasn't the air conditioning we thought at first, it was the heating! If the air conditioner is on, there should be water dripping down the front wheels."

"So, you just went back and looked around the tire print?"

In this regard, Xiaolan was a little surprised.

"That's right."

Conan continued to reply in Hattori's voice:

"When we immediately investigated the rut marks, we didn't find any traces of water droplets! That means there was no air conditioning in the car at the time, so the sound of the wind we heard at that time could only be because the heating was on in the car!"

"However, this trick can be done by investigating the stiffness of the corpse......

Faced with such a situation, Kogoro couldn't help but sigh with emotion, and at the same time understood why the murderer made such an arrangement-

"That's why the murderer wants to bring the shopkeeper and his car off the cliff! Because it is impossible to investigate the stiffness of the corpse until the body cannot be found!"

Heiji Hattori's voice continued to explain.

"How did the car accelerate all of a sudden?"

After listening to this analysis, the astrologer Maria Toda raised a little doubt at this time.

And Conan continued to analyze in Hattori's voice:

"Probably because of the bumps in the road, the feet of the corpse, which had already softened, completely slipped off the brake pedal. Since there is no deceleration of the brakes, the speed of the car will naturally increase. And the cloth on the dashboard is also to prevent people who are close to the car from discovering that the car is heating on!"

"I see......

Very shocked, Ikuo Kawazu couldn't help but sigh:

"Then all you have to do is watch the car start on its own with anyone in the house......

"That way, the murderer has a perfect alibi!"

Maria Toda said with some admiration.

"So...... At that time, Mr. Toba asked Miss Ayako to stay in the house, so he wanted to create a witness who witnessed the start of the car with him?"

Something incredulous, Xiaolan asked.

"That's right."

Hattori's voice affirmed Ran's words.

But for such a statement, Xiaolan was a little difficult to accept, and her eyes couldn't help but look at Ayako Oki who was silently saying a word on the side-

"But...... Why! If the murderer of the shopkeeper was Mr. Toba, wouldn't that be ...... The person who wanted Miss Ayako's life just now was also Mr. Toba!"

Xiaolan asked puzzledly:

"Aren't they a couple? Why do you want to do that?"

"Because you want to destroy your mouth."

！」

Coldly, Hattori's voice responded:

"Didn't Miss Ayako say it herself—she already knows who the murderer is!"

"What! If so, at that time!"

Surprised, after hearing Hattori Heiji say this, everyone present couldn't help but look at Ayako Oki standing aside, a little incredulous-

"That's right. You should remember, right? Miss Ayako Oki suddenly says that she knows who the murderer is. Because at that time, after she learned from me that there were no traces of water droplets near the rut marks, the murderer's method of using the trick of posthumous stiffness to create an alibi had already been debunked by her!"

Conan recalls the previous situation when Ayako Oki asked Heiji Hattori about who the murderer was before announcing to everyone that she knew who the murderer was, and he couldn't help but say this.

"But if that's the case, she already knew that Toha was the murderer, so why didn't she tell the truth until now after knowing that the murderer also wanted her life!"

Kogoro asked loudly.

"Of course, this is because, Miss Oki Ayako also has her own little abacus!"

Conan continued in Hattori's voice:

"You remember, after hearing Miss Oki Ayako announce that she knew who the murderer was, the anxious Mr. Toba pretended to follow her to the bathroom, but in fact he went to her to negotiate terms. I think that Miss Oki Ayako's note was given to Miss Oki by Mr. Toba at that time, so that Oki Ayako could keep it a secret for him on the condition of the first version!"

"Indeed...... At that time, only Toba could be alone with her."

Ikuo Kawazu said suddenly.

"That's why her attitude will change when she comes back!"

Maria Toda was amazed and said:

"But he's so good that he could think of this trick at that moment!"

"No, the ploy was originally intended for another person. The luckiest thing for the murderer is that Miss Oki Ayako has the same habit of carrying a lighter with her like that person! That's right, the trap in the garage should have been designed for Mr. Fujisawa from the beginning!"
