One day, Maori Kogoro's European spirit broke out. He won a huge bonus when gambling on horses, so he took Bai Yan Zhenyu and others to a high-end restaurant and enjoyed a sumptuous dinner.

After dinner, instead of taking a taxi, they walked home together.

When passing a quiet community, Xiaolan pointed to a house a few meters away and recalled: "I remember when I was in primary school, I often fed John, Mr. bankou's pet dog with my new arrival here. I don't know how it is now..."

After listening to Xiaolan's words, Conan also recalled things in primary school and said with a smile: "sister Xiaolan, Yuantai and I came here to play a few days ago. I saw John here. It looks very healthy."

"Really? That's great..." Xiao Lan liked the pet dog named John very much. When she heard the news, her face showed a happy expression.

"Bankou justice..." Maori xiaowulang went over, looked at the name of the head of household on the eye plate, and muttered, "I seem to have heard of it somewhere..."

Bai yanzhenyu flashed an unexpected color in his eyes and reminded him, "uncle, he is the lawyer who specializes in handling campus events."

Bankou Zhengyi is a lawyer specializing in youth issues. Although he is not as famous as Fei Yingli, who has the title of "Queen of legal circles", he is also a famous barrister.

Moreover, he once came to Baiyan Zhenyu's school for legal publicity and education, so Baiyan Zhenyu still knows him, but he doesn't have deep contact. Unexpectedly, Xiaolan and Conan know the lawyer.

Just as they were about to continue walking, a woman's scream came from the bankou family, and then a fashionable young woman rushed out of it.

Baiyan Zhenyu and others were surprised. They came to the woman and asked, "Miss, what happened?"

After seeing the crowd, the young woman was greatly relieved, then pointed to the house and said in shock: "the big dog in the house suddenly attacked Xiaogang..."

"I'll have a look."

Hearing that someone was attacked, Bai yanzhenyu immediately rushed into the house and found a large German Shepherd standing at the stairway on the second floor of the house, while a man fell on the slow platform between the stairs.

Conan, Maori Kouro and others also came to the room. After discovering the situation at the scene, they immediately went to check the man's situation. They found that the man broke his neck when he fell from the second floor. At the moment, he had no breath.

"Xiao Gang, Xiao Gang, what happened?"

Not far from the man's side, a wireless telephone machine in a talking state heard the voice of justice and eagerness from the main board of the house.

Conan, who was often pulled by Yuantai to play with John, was familiar with bankou justice, so he picked up the phone and replied, "uncle, I'm Conan. Where are you?"

"Eh, it's Conan. I'm on business in Izu. Are you here to play with John?"

Bankou Zhengyi was surprised that Conan appeared in his house. After saying hello, he asked, "by the way, I seem to have heard Xiao Gang's scream just now. What happened?"

Baiyan Zhenyu patted Conan gently and whispered, "Conan, don't tell him first and let him come back quickly."

"Uncle, John has an accident. It's inconvenient to say on the phone. You'd better come back." Conan nodded and made up a reason to persuade bankou Zhengyi to end his business trip and return here by car.

After hanging up the phone, Xiao Lan called the police as usual. Soon, the police department came down here with a group of hands at dusk.

After some investigation and inquiry, Bai yanzhenyu also knew the identity of the dead and fashionable woman.

The deceased's name was Qian Yuangang, 20 years old. He was a college student living next door. Entrusted by bankou justice, he helped look after the pet dog John during his business trip.

The fashionable woman's name is Sugata Zaomiao. She is Qian Yuangang's girlfriend. Today, she came here for the night at Qian Yuangang's invitation.

After the preliminary investigation of the scene, at dusk, the police department asked the only experienced person, Sugita Zaomiao, "Miss Sugita, can you explain the course of the incident?"

"Well, I came here at about eight o'clock and played with Xiaogang in the living room. Later, Xiaogang received a phone call and talked with the other side for a while. Then he went up to the second floor and put the phone in the big dog's ear. As a result, the big dog suddenly became fierce and rushed to Xiaogang. I ran out of the room because I was afraid, and then met these people."

Facing the police's inquiry, Sugita Zaomiao nodded very cooperatively and described the course of the incident again.

"I see..."

After listening to Sugita Zaomiao's narration, the police department looked at John playing with Conan at dusk and said in a deep voice, "if Maehara was really attacked and killed by John, then he should be treated with drugs."

The so-called drug treatment, that is, injecting John with death medicine, after all, attacking human beings for no reason, will pose a threat to the life safety of others.

Hearing this treatment, Conan eagerly defended John: "at dusk, the police department, Qian Yuan was just entrusted by Mr. bankou to take care of John. Naturally, he is familiar with John, and John is a very smart and clever dog. It is impossible to attack acquaintances for no reason."

At dusk, the police officer understood Conan's idea that "children" like animals and explained: "Conan, although I don't want this, judging from the current scene terrain and the traces left on the dead, it was John who attacked qianyuangang."

Just when Conan didn't know how to refute, the men of the nightfall police department provided a new clue, that is, eight years ago, the just son committed suicide after being bullied on campus, and the victim was Qian Yuangang.

The emergence of new clues made Bai yanzhenyu think of a possibility and said, "at dusk, the police department just heard that Sugita said that the deceased was attacked when he put the phone in John's ear. Is it possible that Mr. Ban Kou ordered him to attack in order to avenge his son?"

Conan's eyes lit up and echoed: "yes, John's breed is German shepherd. As long as he has special training, he can control his behavior through some signals."

German Shepherd is a smart dog with strong working ability. Therefore, it is active all over the world as a military dog, police dog, search and rescue dog, guide dog and shepherd dog.

As John's master, Mr. bankou did have the possibility of ordering John to attack Yuan Gang for his son's revenge. Especially before the attack, he also spoke to John by telephone, which greatly increased the possibility.

"It's really possible, but we'll wait until Mr. Ban Kou comes back. As for John, take him back to the police station and put him in custody."

In many years of police work, the police department has encountered many incidents of attacking others with trained pets at dusk, so they think what Bai Yan Zhenyu said is very reasonable.

Before long, the police completed the investigation of the scene, blocked the scene, and took John back to the police hall.

Baiyan Zhenyu and others also left bankou's home and returned to the office to rest. Early the next morning, they left for the police department to meet bankou Zhengyi who came back from other places.
