The next day, Officer Twilight receives a call from the police who says that his daughter has been kidnapped and demanded a ransom.

In a case like kidnapping and ransom, Officer Twilight still didn't feel at ease and handed it over to Kei Suzuki to handle it alone, so he led the team to set off. Originally, Kei Suzuki was also going to go, but Officer Twilight handed Kei Suzuki another case to deal with.

After receiving the case file from Officer Twilight, Kei Suzuki learned that last night, John, the dog of the lawyer Sakaguchi Masayoshi who was on a business trip in Izu, jumped down the stairs and knocked the tenant of his house, Maehara Tsuyoshi, down the stairs, only to die after Maehara just fell down the stairs and hit the back of his head against the wall.

Although neither Masayoshi Sakaguchi nor the people who lived near him believed that John's dog would attack people casually, Tsuyoshi Maehara's corpse had made it clear to everyone that it had indeed killed a person. If there was no other reason for this, then John's secret execution was the only consequence of it.

It's just that Officer Twilight has a little doubt about this case, and always feels that something is wrong. But he didn't figure out what the problem was, and now there was a new case, so he handed over the case to Kei Suzuki. He went to deal with the kidnapping case for ransom.

Kei Suzuki looked at the transcript of the only witness to the case, that is, the deceased's former former former Tsuyoshi girlfriend, Miss Sanae Sugida:

"Masayoshi Sakaguchi, a well-known lawyer specializing in juvenile issues. My son also committed suicide at home 8 years ago because he was bullied by his classmates. My wife also died 5 years ago because of her son's suicide, which caused her to be overhearted,"

"Lawyer Sakaguchi went on a business trip, so I asked Xiaogang to help me look at the house. So we were going to stay here for the night, and it was close to 9 p.m., and while we were playing, the host's phone rang out of nowhere. He asked Xiao Gang how his dog was, and Xiao Gang said that he was just staying upstairs. Then Mr. Sakaguchi said that he wanted to talk to John, and Xiaogang called the dog's name John a few times, but John never came down from the upper floor. ”

So Xiao Gang had no choice but to go upstairs and put the phone to John's ear. At this moment, the house bell rang, and then the dog pounced on Xiao Gang down the stairs. Then people who passed nearby ran in, and they found that Xiao Gang was dead. ”

And then there is the transcript of lawyer Masayoshi Sakaguchi:

"I just asked if there was anything going on at Maehara Tsuyoshi's house, and if anything had happened. After Xiao Gang said that there was nothing to do, I said that I wanted to talk to John and wanted John to answer the phone. ”

Seeing this, Kei Suzuki also saw Officer Twilight's questioning, "What did you say to John?" ”

Sakaguchi said, "I just habitually said goodnight to John. ”

Officer Twilight: "Anything else?" ”

Masayoshi Sakaguchi: "Other than that, I just said John, how are you?" How are you, John? Then I heard John's barking and Xiao Gang's screaming. ”

There is also an investigation of the relationship between Sakaguchi's lawyer and the deceased by Officer Twilight: the deceased Xiaogang and Sakaguchi's lawyer's son Masato were classmates in junior high school, but Masato hanged himself because he was bullied by Xiaogang when he was in junior high school. All of this was written down in Masato's diary, but I suspect that Sakaguchi's lawyer may have a grudge against Xiao Gang because he saw his son's diary.

Moreover, Sakaguchi's lawyer's wife died very early, and Masato is his only relative, so it is simply certain that he has hatred for Xiaogang.

However, lawyer Sakaguchi said that 8 years ago, at the mourning hall of the righteous people, when he saw Xiao Gang constantly crying and making amends, he finally forgave Xiao Gang. Soon after, he left Tokyo and transferred to Kansai because of his father's work.,Two years ago, Kogashi came to Tokyo again because he was admitted to university.,And in the spring of this year, he moved next door to Sakaguchi lawyer.。

Lawyer Sakaguchi seemed to be taken aback when he saw Xiao Gang, but after such a long time, Lawyer Sakaguchi seems to have forgotten about this matter for a long time, and often invites Xiao Gang to his home for dinner.

Looking at the various doubts written by Officer Twilight on the case, Kei Suzuki decided to meet the lawyer Sakaguchi. However, before leaving, Keiya Suzuki still had to find a police officer who had been to the scene yesterday, so he asked the people in the office: "Takagi, Chiba, Sato, have any of you been to the scene of this case last night?" ”

Hearing Kei Suzuki's question, Takagi stood up and said, "Officer Suzuki, I went to the scene yesterday. Are you going to go over now? Do you want me to go with you? ”

Kei Suzuki nodded and said, "Of course, let's go!" ”

After getting into the car, Kei Suzuki said to Takagi: "Officer Takagi, I read the case file given to me by Officer Twilight, and I already have a general understanding of this case, do you have anything to add?" ”

Takagi shook his head and said, "Officer Suzuki, Officer Twilight and I were able to investigate last night and we have already written it in the case file." I don't have much more to add than that. ”

When Kei Suzuki saw Masayoshi Sakaguchi from the car, he said to Takagi, "I've now determined that this person must be the murderer." It's just that we haven't found evidence of how he ordered John, Takagi, think about it, what happened yesterday when the crime happened. ”

Takagi doesn't have any doubts about how Kei Suzuki judged that lawyer Sakaguchi had killed someone. After more than half a year, Kei Suzuki's accuracy in this regard has been verified many times, and it is worth believing in Takagi.

After thinking about it, Takagi said slowly, "After the deceased received a call from Sakaguchi's lawyer, he went upstairs to give John the phone. However, after John heard Sakaguchi's lawyer say how John is and how are you John, he knocked the deceased down the stairs and died on the stairs. ”

Kei Suzuki groaned and said, "In this case, the last words of Sakaguchi could be the signal for John to attack?" ”

Takagi shook his head and said, "Officer Twilight also thought about this yesterday, but when Sakaguchi said it again later, I didn't see any special reaction from the dog. ”

Kei Suzuki pondered, "Did Sakaguchi go to train John?" ”

Takagi said: "We already asked yesterday, and people in the neighborhood said that they had never seen Sakaguchi training John. However, every weekend for the last three months, Sakaguchi would take John out, and after we asked Sakaguchi, Sakaguchi said that he was taking John for a walk in the countryside, where the place was more empty and allowed John to exercise. ”

Keido Suzuki: "In this way, it seems that Sakaguchi will have enough time to train John." ”

Takagi hesitated, "But we tried it yesterday, and what you just said didn't work!" ”

Kei Suzuki thought for a while and said, "What do you need to do if you train a dog in general?" ”

"It's usually called by its name first?" Takagi said uncertainly: "Then give it an order!" But Sakaguchi only said John, how are you, how are you, John? And John didn't react when he heard it! ”

Speaking of this, Takagi suddenly realized, "Officer Suzuki, you mean that this sentence is not an order to attack, but to add up the other voices in front of you, right?" ”

Keido Suzuki: "I don't know if that's the case, but I believe it's more likely!" ”

Speaking of which, Kei Suzuki flipped through the case file handed to him by Officer Twilight and said, "By the way, what voices did John hear yesterday?" At the beginning, Tsuyoshi Maehara and Miss Sanae Sugida had been playing, so it shouldn't be counted at this time. From hearing the phone ring, to what Sakaguchi said, was there any sound in between? ”

Takagi also took out his police handbook and found the confession recorded yesterday and said, "According to the confession of Miss Sanae Sugida, it seems that the clock of the Sakaguchi family has sounded?" Nothing else. ”

"Clock?"

Faced with Kei Suzuki's question, Takagi said: "Well, the clock in the Sakaguchi family seems to be the kind that chimes the time on the hour, and when Maehara was just killed, it happened to be 9 o'clock ...... night. ”

Then Takagi paused, and shouted excitedly, "I see, it's the bell!" ”

In Kei Suzuki's surprised eyes, Takagi said loudly, "Officer Suzuki, I know." Sakaguchi's order to attack should have 3 sounds, first the phone ringing, then the 9 o'clock bell, and finally the sentence John How are you, how are you John. ”

After thinking about it, Kei Suzuki got out of the car and said, "Takagi, let's go visit lawyer Sakaguchi!" Ask him to cooperate with our experiments. ”
