At night, a full moon hangs in the sky, and the bright moonlight shines on the road.

On the streets of Kelma, a teenager wearing headphones rode a bicycle from east to west.

The boy has darker skin and is carrying a brown schoolbag behind him, which looks heavy.

The night wind was a bit chilly, and there were no pedestrians in sight. Occasionally, a car passed by.

Ahead was an intersection with no street lights. The boy observed that there were no cars on the left and right roads and passed directly through the intersection.

Suddenly, a black Volkswagen sedan came from behind and hit the boy on the bicycle directly from the side and rear.

With a sound of "Bang!", the boy was knocked away and fell heavily to the ground.

…

Robbery and Murder Division 1 Squadron.

Luke held a morning meeting as usual, standing next to the whiteboard and marking the newly acquired clues.

At this time, two tree diagrams were marked on the whiteboard. At the top of the tree diagram was the victim's name and photo.

The first victim, Yoshimi Hashimoto.

The second victim, Ma Jiehui.

At the same time, several people involved in the case were also marked.

This kind of tree diagram helps the police analyze the case and makes the relationship between the people involved in the case clear at a glance.

Luke sat on the chair next to the whiteboard and said, "Everyone, tell me about the clues you have investigated."

Jenny said, "We searched the car of the second deceased, Ma Jiehui, and checked his driving recorder. He spent most of his time in restaurants and didn't drive much.

I have not recently been to the street or apartment where the first deceased Yoshimi Hashimoto prostituted herself."

Previously, Luke speculated that the second deceased, Ma Jiehui, might have been a guest of Hashimoto Yoshimi, thus establishing a connection between the two. Now it seems that this speculation is likely to be untrue.

"Does anyone else have any new developments in the investigation?"

Xiao Hei said, "We investigated Melanie Hickman, the assistant of the deceased Yoshimi Hashimoto. Some time ago, she went to see a psychiatrist."

This coincides with Luke's speculation. Before, he took notes on Melanie Hickman and found that this woman was somewhat paranoid.

She was the assistant of the deceased Yoshimi Hashimoto. If she did not complete the work assigned by Yoshimi Hashimoto on time, a normal person would usually tell the boss directly, which would be nothing more than a scolding.

But Melanie Hickman was different. In order to conceal the incident, she lied about the fact that her office had been burglarized. This way of handling things made Luke feel a little abnormal.

The deputy said, "If Melanie Hickman really has a mental problem, then her behavior cannot be understood by normal people's thinking.

Even if there is no sufficient motive to kill, someone may still kill someone.

Judging from her previous behavior of reporting false police reports, she is the kind of person who is completely reckless in order to cover up a trivial matter.

Suppose, her mental problems become more severe and she becomes more paranoid.

This time, she did not complete the work assigned by Hashimoto Yoshimi, and she could not tell Hashimoto Yoshimi frankly, or even face her. In order to escape this situation, would she kill Hashimoto Yoshimi?"

Luke frowned and thought, killing someone because he didn't complete the work and had no face to face the leader?

It's impossible for a normal person to do such a thing, but is Melanie Hickman's mental state still normal?

I guess only psychiatrists know.

"Marcus, look up Melanie Hickman's psychiatrist."

"yes, sir."

"Dong dong..."

The door of the office rang, and forensic doctor Sheila opened the door and walked in, "Good morning, is there any progress in the case investigation?"

Luke said, "We have investigated the surrounding relationships between the two deceased people, and so far we have not found any direct connection between the two deceased people, and the people involved have no clear motive for the crime.

We have now discovered that one of the people involved may have mental problems, which may be a direction for investigation.

Do you have any new discoveries over there?"

Silla pulled a chair and sat down, "The autopsy of the second corpse has been completed, and the autopsy report will have to wait until the afternoon. However, I discovered a new situation, a new corpse to be precise."

"What's the meaning?"

"Last night, there was a hit-and-run case on the streets of Kelma. The deceased was a 12th grade student. He was stabbed in the chest and the letter 'm' was carved on his face by the blade.

Considering that the two previous deceased persons also had letters engraved on their bodies, I felt that this case might be related to the two previous cases.

Of course, this is just my guess."

"Did the deceased be hit to death or stabbed to death?"

"I don't know either. Other forensic doctors were responsible for the autopsy of this body. We just exchanged some 'rumours'."

Luke asked, "Who is responsible for this case?"

"Old Jeff."

Jeff Brandy, captain of the Robbery and Murder Division 3 Squadron.

"OK, I'll talk to him."

After Luke sent away forensic doctor Sheila, he did not go directly to Jeff Brandy.

There are four squadrons in the Robbery and Murder Division, of which Squadron One and Squadron Two are directly in charge of Red.

The 3rd and 4th Squadrons are managed by Magna Met, Deputy Director of the Division.

According to the vice team, the relationship between Magna Met and Red is not very good.

Although this rumor has not been accurately verified, he feels that it still has some basis.

Luke thought for a while and decided to ask Red first to coordinate...

It's approaching noon.

A white man walked into a squadron office.

He looked about fifty years old, tall, with a short beard, slightly red cheeks, and said in a loud voice, "Ladies, we are here to receive guests."

The deputy team member flapped his right hand and said, "You bastard, you haven't brushed your teeth for a long time. It feels like you've eaten dog shit."

"It didn't take long, it seems like it was the last time you got divorced, haha..." The white man laughed.

Luke heard the commotion and walked out of the office. Seeing the deputy team's face looking a little ugly, he advised, "Jeff, I was just looking for you.

Come in and talk."

"No, it's safer for me to stand at the door." Jeff Brandi directly threw a piece of information on the table, "This is the file from last night's case.

Also give me a copy of the files on the two letter cases that you are responsible for, and we can each investigate our own."

Luke ordered Jenny to copy the files of the other two cases, and then said to Jeff Brandi, "There are new developments in the case, please communicate in a timely manner."

"It depends on the situation." Old Jeff shrugged, "To be honest, I don't have this habit."

Luke walked over and said, "Sit down and have a cup of coffee and talk about the case."

Old Jeff glanced at the deputy team, sat a little further away, and said, "The patrol police were the first to discover the body. At that time, they thought there was a traffic accident or an accident. When they got closer to check the condition of the deceased, they discovered the face of the deceased.

He was engraved with letters and was stabbed in the chest with a sharp knife. Later, the case was handed over to our No. 3 Squadron.

There were no traffic lights or surveillance at the intersection where the incident occurred, and no witnesses have been found yet.

The deceased's belongings were not missing, so it looked like a premeditated vendetta.

The deceased was only 17 years old and attended a private high school. He was of Indian origin. According to the deceased’s mother, the deceased was a good student with both good character and academic performance. No clear suspect has been found so far.”

Later, Luke also briefly introduced the two previous alphabet cases.

Old Jeff listened noncommittally. After Jenny copied the dossier, he picked up the dossier and prepared to leave.

Luke politely walked him to the door.

Old Jeff patted Luke on the shoulder and said, "Man, do you want to make a bet to see who can catch the murderer first?"

"What's the stakes?"

Old Jeff said, "The loser please drink."

"Isn't it a treat for the party who should win?"

Old Jeff shrugged, "I've been a little tight lately."

Luke smiled, "Then you might want to consider taking it on credit."

"See you at the bar." Old Jeff smiled and walked away.

Luke wrinkled his nose, closed the office door, and asked the deputy team, "Does this guy often drink during the day?"

The deputy shook his head, "If this bastard could stop drinking, he would be the director of the Robbery and Murder Department.

A hopeless guy."

…

Luke opened the file and began to check the circumstances of the third suspected victim of the 'Alphabet Case'.

Name, Aamir Murthy

The time of death was around 10 p.m., and the fatal injury was a stab wound to the chest. This is why the case was transferred to the Robbery and Murder Division. If it was just a traffic accident, the patrol police would be responsible.
