Since the location of the murder was not within the jurisdiction of Bureau 21, Kim and Hailey were not qualified to take over the case.

Soon, a pair of police detectives, one old, one young, one black and one white, came to the scene and took over the case. The old black policeman seemed to be very famous. When he appeared, all the police present greeted him, even Hailey.

No exception, Jin was a little shy and did not come forward, but it could be seen from her facial expression that she also knew this black police detective.

Kay inquired curiously and found out that the black police detective was also a famous figure in Chicago. His name was William Somerset, a criminal police officer in the Chicago Police Department and a homicide expert. He had been a police officer for 42 years.

Over the years, his crime detection rate has been the highest among the entire Chicago Police Department. However, this legend is coming to an end. He is old. In the past two years, everyone knows that William no longer has the drive he had when he was young.

.

He muddles along at first, but most people can understand him.

He is 65 years old and should have retired a long time ago. The police profession also relies on youth. In his previous life, like Kai, who was a front-line detective in the criminal investigation team, there were young people in their thirties, and those in their forties were all old comrades.

The older you get, the harder it is to handle the workload. The fact that William is still working on the front line at the age of 65 is a legend in itself.

But people who are really familiar with William know that there is actually still gas in William's gas tank. His decades of regular life have made his physical condition not bad, but his heart is tired. Over the years, he has been almost every day

He worked hard every minute, but he also saw and felt too much misfortune, which made him feel extremely tired.

No one can understand how he feels. He once worked diligently to bring criminals to justice as much as possible, but in the end he found that everything he did could not change the city at all. William once said this: "

In this city, when a woman encounters a robbery, she has to call for help, because someone will help you, but for help, residents are afraid of getting into trouble."

This sentence is also the reason why William wants to leave the police station. Because the people here have lost their original "concept of humanity". Everyone has become numb, and the police are just staff who deal with numb corpses. Whenever there is a case

Now, when it comes to illegal things, the police seem to be the ones who deal with the aftermath. Their work cannot improve society, nor can they change people.

This is such a tragedy. William feels that what he has insisted on and fought for in his life has become worthless...

"Hi Kim, how are you doing?"

After William greeted others, he actually said hello to Jin. This old black policeman could actually remember the names of everyone present. Jin was also a little flattered to see the police legend greeting him.

But the white policeman next to William was a little impatient. He was the complete opposite of William.

William is black and he is white. William is a little old man with a kind face. But he is a powerful and tall man. William always has a friendly smile, but he always looks impatient with a frown.

"Hello, Kai. I know you. The case you handled last time in Bureau 21 was really great. I've always wanted to meet you, but I didn't expect it to be like this." William obviously knew Kai's deeds, but

For some reasons, William did not say much about Kai's great achievements.

This is not because the Chicago police are jealous of being able to hide Kai's record. On the contrary, it is to protect Kai in a sense. For police officers, especially those on the front line, being famous is not a good thing, especially someone like Kai.

, police officers with human lives in their hands. Their information is kept strictly confidential to prevent revenge from some people with a grudge.

"Hello, I've heard about you too, William." For an old man who has been working on the front line for forty years, Kai needs to maintain respect no matter what.

"Okay, let's talk about the case. The police department doesn't pay us just to chat." Unexpectedly, the white policeman had no intention of letting them continue chatting.

His attitude made everyone present frown.

But William had a good attitude. He didn't care what the young man said, but took the initiative to introduce himself to him.

"His name is David Mills, and he's here to replace me."

Kai nodded as a greeting and then gave a brief description of the case.

Both William and Mills listened very seriously. Mills even took out a small notebook and wrote down all the important points. Seeing his serious attitude, Kai felt a lot better about him. For Kai

, a policeman’s behavior is almost nothing. Anyway, policemen are not social butterflies, so it’s good if they can handle cases seriously.

William was also very serious, but as he listened, his expression changed. He is a real veteran detective and has a natural sense of the follow-up development of many cases.

"Trouble..."

"Indeed. The murderer obviously has his own purpose. This is not a simple murder case."

"Why do you say that?" Mills asked immediately.

Kai glanced at Mills, and then said, "The murderer did not simply want to kill the victim. If he just wanted to kill the victim, one shot would solve the problem. There is no need to go to such trouble, and there is no need to leave a mark at the scene.

"When Kai said this, he also pointed to the words on the back of the refrigerator.

"It's more like he was expressing something, and the victim was just a tool for him to express his point of view! From this point of view, I even doubt that the murderer and the victim themselves have no emotional connection."

This kind of case is the most difficult to handle, because once there is no connection between the murderer and the victim, it means that the investigators cannot detect the case from the victim's interpersonal relationship. In almost 90% of homicide cases,

All occur within the victim's interpersonal network.

After thinking about it, Kai threw out another theory.

"Gluttony, what can you think of, don't think too much, what is your first reaction?"

"Seven deadly sins..." William said in a low voice.

"That's right! If...that means there will be another murder." At this point, Kai felt a little heavy. Don't forget, Susie's mother had contact with the victim before she disappeared! Now!

The innkeeper is dead, what about Maria?

More importantly, there is one more crime among the seven deadly sins——!

And Maria's career...Maria's disappearance at this critical point can't help but make Kai think.

Kai didn't stay at the scene for long. After all, this was someone else's case and he couldn't always stay there.

…

Back at the hotel, as soon as Kai opened up about himself, Susie ran out of the room opposite. Seeing the expectant expression on Susie's face, Kai really didn't know what kind of expression he should give her.

Seeing Kai looking a little embarrassed, Susie said nothing and just returned to the room disappointed.

Ever since Maria disappeared, Susie has become like this, extremely silent. She used to like to pester Kai, but now, she talks to Kai at most three times a day, and Kai usually does the talking, while she remains silent. Kai is very

He was worried about her mental state, afraid that she would become the same as before again. But he didn't have any good solution.

Kai also arranged for Kim and Hailey to enlighten her, but it turned out that... it was of no use.

And just when Kay was in trouble, William and Mills also got into a quarrel.

William doesn't want to take this case. He will retire in a few days. He also doesn't want Mills to take this case because he is too young. His fiery and impatient personality is his Achilles' heel. Mills

He was very disappointed. When he learned that he was going to take over the role of police legend William, he was very excited. Because William has always been a benchmark in the industry. Although Mills has a bad temper, he still has reservations about the social chaos he has seen.

He has a strong sense of justice and hopes to do his best to improve people's sins and dark sides.

Now he is very disappointed to see that William, a benchmark in the industry, is beginning to be timid about crime. He and his wife Tracy moved from Springfield to Chicago, not just to hang out here. At first, Tracy did not agree to come here.

It was a chaotic city, but Mills believed that only here could he take on some important cases, so after his persuasion, Tracy agreed.

What William is doing now makes Mills feel like he has been deceived.

The two broke up unhappy.

Mills returned home and found that his wife was preparing dinner. Mills had just arrived in Chicago and was in a bit of a hurry, so he did not have time to look for a house, so the place they live in now is not a good one. It is next to the Chicago subway. Every time

A train passed by and the whole house shook.

But Tracy never complained. On the contrary, she was very optimistic and said that this way they would not need an alarm clock.

Seeing Tracey's busy figure, Mills immediately softened and was no longer as aggressive as he was at work.

"Hey, Tracey, what day is it today? It's so rich?" Mills asked a little surprised when he saw the steak that Tracey brought out. Although Mills looked like this, he clearly remembered their various anniversaries.

Chu. Today is by no means an anniversary. Could it be the day of holding hands for the first time? Mills thought about it and found that it was very close, but they had never celebrated this day before. What happened today?

"I invited two important guests today, so it must be rich." Tracy said casually while busy without even raising her head.

"who?"

Mills asked casually while playing with his two dogs. He actually didn't want Tracy to stay at home all day. They had been in love since high school, and they were separated in the middle. He went to join the army and Tracy went to

They were in college. But the distance did not affect their relationship. When Tracey graduated and Mills retired, they got married, and everything went smoothly. Mills never asked Tracey to stay at home and be a full-time housewife.

Come on, Tracy graduated from a prestigious school and can have a better future. There is no need to stay at home and serve a poor policeman like him.

But Tracy told him that she liked this kind of life.

Mills knew that Tracey was worried about him. She was worried that he would not have a hot meal when he came home, and that no one would greet him when he came home. She also wanted Mills to understand that she would always wait for him to come home.

"Pepper is here!"

"She came to Chicago? Isn't she in Los Angeles?" Pepper is Mills's college classmate. Talking about the two of them, Mills also feels that the world is really amazing. There are two people so similar in this world. Pepper is from Connecticut.

Tracy is from Illinois, and the two didn’t even know each other existed until they met at Yale University and became classmates and roommates!

However, after graduation, Tracy chose family, while Pepper went to Los Angeles to pursue her career. It is said that Pepper has now become the secretary to the president of the famous Stark Industries.

"It is said that Stark Industries is going to hold an industrial expo in the old factory area of ​​Chicago. Pepper is here to inspect and make preparations."

When Mills heard this, although he didn't show it on his face, he couldn't help but feel a burst of unspeakable guilt in his heart. Pepper and Tracy's conditions are almost exactly the same. They are both outstanding graduates from prestigious schools, the same height, and the same appearance.

, Pepper now has a smooth career and is high-spirited. But for him, Tracy...

"Are you listening to what I'm saying?"

Tracy kept talking, but there was no response for a long time, so she shouted loudly.

"What?"

"I said, I also invited William!"

"who?"
