In the small office, the atmosphere suddenly became a little strange.

Miwako Sato, who also smelled something wrong, had tense muscles all over her body, her hand had been removed from the table for some time, and her sharp eyes were staring at the man sitting behind the desk in front of her.

Something is wrong with this person.

The policeman's instincts made Miwako Sato's heart vigilant.

Natsuki Katsushi didn't care about this as if he hadn't seen it. The slender index finger pushed the gold-rimmed frame on the bridge of his nose, and the corner of his mouth smiled and groaned: "That's right, I'm too worried, a person as powerful as Uehara Criminal should be able to arrest the criminal soon." ”

"It may be a bit of a boast to say that, but I think you're right."

Tilting his head slightly in agreement, Katsumi Uehara stretched out his left hand and picked up the water cup on the table, handed it to his lips, and moistened his throat: "The police are confident that this bizarre serial murder case will be completely solved within 3 days, so you can rest assured, Doctor Natsukikawa." ”

Miwa Sato, who heard her partner say this, resisted the urge to turn her head and ask him, and continued to maintain the best alert posture, always on guard against possible conflicts.

"3 days? Is it so fast? Xia Mu Chuan also raised his eyebrows, took off his glasses and wiped the white mist that poured on the lenses because of drinking coffee, and then put them back on: "But I see that the police don't seem to have announced this news in the evening news." ”

"I wanted to say that, but my boss wouldn't allow it. After all, that damn bastard was just crazy, and his neuropathy wasn't enough to describe what he did.

"He's more like a terminal testicular cancer patient who came out of an insane asylum, and likes to strip naked on the street to prove that he's not cut. To be more precise, it is probably the incomplete development of the cerebellum, the complete development of the brain, commonly known as intellectual retardation. ”

The index finger of his right hand tapped near his temple, and Katsumi Uehara, who was holding the cup in his left hand, raised his eyebrows: "You're right, Doctor Natsukikawa?" ”

"Indeed."

Xia Mu Chuan nodded undeniably, his elbows bent on the desk, and he crossed his ten fingers against his chin and said solemnly: "But as a doctor, I don't think Uehara Criminal's words are very respectful to patients with mental illness and testicular cancer."

"From a medical point of view, patients should not be ridiculed, and they are one of the most life-loving people in the world who can actively cooperate with treatment.

"No one wants to be sick."

"Sorry, I may not have made it clear."

Placing the cup with half of the water left on the table, Katsumi Uehara shook his head with a smile: "I don't mean to be disrespectful to any group of people who actively love life, on the contrary, I respect and admire that group of people who love life.

"You also said that people have good and bad luck, who knows if the mouse made this series of perverted actions because of these diseases caused by nervous disorders."

"Makes sense, maybe I'm more sensitive because I'm a doctor."

Natsuki Kawa also leaned on the back of the swivel chair, his gaze moved away from Katsumi Uehara, and instead fell on Miwako Sato: "So, Sato Criminal, do you have any other questions to ask?" ”

"Yes, however, I think you may need to go to the Metropolitan Police Department to answer the next question, Dr. Natsukikawa."

Miwako Sato, who raised the phone in her hand, said in a condensed voice.

………………………………………………

Natsukigawa Jiya, 34 years old. After graduating from the Faculty of Medicine, he entered Yonhua Central Hospital for an internship and has been working ever since. Judging from his resume, this guy is a model of achieving personal class leap by reading. The appearance and height are not bad, and it is the perfect template for honor students. ”

An hour and a half later, the Metropolitan Police Department searched the office area of the three departments.

After summarizing the personal information that could be retrieved temporarily into a file and handing it to his boss, Kazushi Chiba was puzzled in his tone: "Are you sure this person is the murderer?" ”

"It's not that we're sure he's the murderer, it's his words and actions that make us suspicious." Miwako Sato, who took the document, frowned and looked at it, and briefly explained the man's previous performance in the hospital.

"Perhaps...... Are you too sensitive? Chiba and Shin still felt a little unreasonable: "If he is really a prisoner, then why did he do this?" Why is it being brought to your attention? ”

"No, it's just a provocation, it looks like he's not convinced that he didn't blow up the hospital."

After adding the information and name of "Natsukigawa Jiya" to the blackboard, Katsumi Uehara, who had put on the cap of the pen, turned his head and knocked on the board: "Do you remember the letter of challenge he sent to the police?" ”

"Speaking of this-Uehara Crime, I've already found out who Jiro Sakai was who sent the second letter to the Metropolitan Police Department last time." Hearing this, Takagi hurriedly returned to his seat and picked up a document, trotted back and handed it to Katsumi Uehara.

"We called up surveillance at multiple nearby intersections and finally locked down the person who delivered the package at the door of the Metropolitan Police Department. According to his confession, there was a man who called him two weeks ago and said that he could get a large sum of money for helping to do it. ”

"He didn't know it was a crime?"

He said he knew, but his father was in a car accident, and although he was saved by surgery, he needed a lot of money for every month of treatment, so he was tempted.

"The most important thing is that the other party promised to pay him in full in advance, and promised to wait until he paid all the medical bills before acting."

“……”

“……”

Katsumi Uehara and Miwako Sato, who were looking through the documents in their hands, looked up in unison, and saw that Wataru Takagi, who was reporting the situation, was a little overwhelmed for a while-

"What's wrong?"

"Rice Flower Central Hospital, a life-saving center." One glance and ten lines looked at the information in his hand completely, and Katsumi Uehara said in a deep voice.

"I guess we should know the person who sent the money and the person who called." Miwako Sato turned her head and raised her chin towards the folder in her partner's hand.

"The location of the number is a public phone booth, and the monitoring is still checking the people who have used the phone booth according to the time. However, the money was found and the check was used. ”

"Whose account?"

Katsumi Uehara turned his head, looked at the name on the blackboard, and said in a deep voice, "The first deceased in the serial murder case, Dr. Taiga." ”

“…… Two weeks ago, shortly before the serial killings. Miwako Sato frowned, always feeling that her thoughts seemed to hit an invisible wall: "Takagi, in which bank did this Sai Jiro exchange checks?" Was there anyone with you at the time? ”

"The Mitsubishi Bank Rice Flower Branch, the staff who handled the relevant business for this Sai Jiro was called Masami Hirota.

"We also came in for questioning, and she and the bank's surveillance at the time could prove that Jiro Sakai was indeed alone when he came to exchange the check."
