Sherlock had some clue before leaving Butz Hospital, if this person could kill someone near the University of London and not be discovered, then her location must be very close to the scene of the crime or some secret passage, the most important thing is that the time of her murder was not late at night, but in broad daylight, it was really ...... It's very daring.

So he ran to the University of London, and he thought that those stupid cops must have left something behind and didn't find it, and he had already deduced that this was a woman, a calm criminal who was probably over thirty years old, not very tall and powerful, and very calm, she was also related to the three victims, this was not a simple murder case, but a revenge, she was using Thirteen to mock the last victim, because Thirteen still meant betrayal.

From betrayal to ridicule, there must have been a lot of experience, even ...... This thirteen has other meanings.

He had to rely on his own strength to solve the case, and he would count on the stupid Scotland Yard people that the case would never end.

So he found the clue, a small passage that no one would find, just enough for a thin man to lead to guò, and he got into it and followed the scent left by the woman to find the exit, in front of a small dilapidated apartment.

The apartment was dilapidated and uninhabited, not even a homeless man, and the location of the apartment was very delicate, at the junction where the three bodies were found, and if he was not mistaken, this was probably the place where the second victim died. Truth be told, a secluded and uninhabited place is certainly a good place to kill, and even after confusing the police with the sights and ears, no one will notice it anymore.

Then Sherlock spotted a shadow of a hurried car away, and he chased after it but didn't, but he was sure that it was ninety-nine percent the lady. Coupled with the evidence he found later, he was even more sure that it was a murder scene, and only the murderer would come back here, because she was worried that she had missed something and came back to check.

Sherlock found the family of the last victim, Mr. Horton Buck, according to the clues he already knew, a married man, a wife and children all lived in a high-end apartment, worked according to the hours every day, received a fixed high salary, and got along with his wife and neighbors happily, to be honest, this Mr. Buck is like a perfect person, but overly perfect people are fake.

He wasn't a scotland yard fool, he asked Buck's wife if there was anything strange about Buck, his wife was a simple person, she had just experienced the tragic murder of her husband, she was going to tell Sherlock almost everything, and she mentioned that Buck sometimes had nightmares at night, calling a name in his dreams, and he would be nervous for the rest of the day after the dream.

"Name? Nightmare? Sherlock raised an eyebrow, if one person often calls another person's name, or is associated with nightmares, then there must be an untold story in it.

"Do any of his friends have the last name Brown or Felton?"

"It seems to be, I don't know, but once after a nightmare he called someone, and I heard the name Brown?"

The corners of Sherlock's mouth went up, and he knew that something must be going on, and he finally asked for the name, "Aliana".

Sherlock started by the name Aliana, which was not a common name, and he guessed that the murderer was similar in age to Buck and the others, but it could not be revenge for his own children or anything else, because this Mr. Buck alone could be called a good student after entering the University of London. So Sherlock also focused on the only transfer in Mr. Buck's life, and luckily he found Brown and Felton on the list.

He checked the roster of students for those two years, and there was only one named Alina, but he had died.

It is said that it was a suicide, but after her death, the remaining two of the three victims changed schools, and the timing was too coincidental, the main thing is that Alina has a twin sister, which happens to be about the same age as the murderer according to the time.

If it is said that the three Bucks killed this Alina White, then her sister's sudden revenge is also in the past, then Thirteen means ......

"Atonement."

Damn, this Inspector named Gehr or something is a step ahead of him.

Yes, atonement, he also thought of it, and even guessed where this murderer would appear.

"You know, you know!"

Lestrade shrugged as he looked at the jumping bastard, and said apologetically, "It doesn't look like you're much faster than me." ”

"You're showing off!"

It looks like an apology but it's actually a show-off, and the broken Lestrade shrugged, even if he was showing off, how? Could it be that the bear child still wants to pounce on him and bite him, but he can't do it! Besides, he has a bear child in his family who has a high IQ and is not lost to Sherlock at all, and he just wants to show off.

"We've found out the relationship between the three people and we've locked up a suspect."

The whole thing became simpler after peeling back the cocoon, Sherlock exhaled that he decided not to deal with a goldfish with a bit of intelligence, well, he grudgingly admitted that Lestrade still had a bit of intelligence.

"Let your fools go to this address first, which is the first scene of the death of the second victim."

Sherlock threw an address to Lestrade, and now he was even more excited about the murderer, and he bet they would meet the killer soon, because today was a special day, wasn't it?

"Donovan, I'll leave it to you."

Donovan looked at Sherlock and Lestrade with a shocked look, she had no idea that Lestrade would ask for help from a "madman" who suddenly appeared. But apparently this Sherlock provided a clue that was more important, and they never found the first scene.

"Very well, and what else did you find?" Lestrade shifted to a comfortable position, "except for atonement." ”

Lestrade not only knows how to smooth the bear child's hair, but is also a good bully, and the bear child with a personality like Sherlock is the most unacceptable blow to this kind of blow.

"Childish!" Sherlock screamed, but Lestrade didn't care, keeping a childlike heart was good for his health, it was Hannibal's opinion.

The angry Sherlock stomped his foot vigorously, and then reluctantly began to talk about what he had found, and his speed of speech was probably because he was stimulated by Lestrade, and Sherlock found out that the file in the hands of Lestrade was the cause of the whole incident, and Lestrade and their investigation just made up for the cause of the death of the person called Alina.

"I know where the other Miss White will be today."

Sherlock said triumphantly, he knew that Lestrade could not think of this truth, it was on this day that Aliana White chose to die more than twenty years ago, and today was the day of her death, and he thought that after the revenge was completely over, the other White would definitely go to his sister's tombstone to inform her.

"Where is Miss White buried?"

"Talk as you go."

Lestrade asked his own police to follow Donovan when he was out in the field, and after he said his destination, he was urged by Sherlock, and they didn't have much time.

"Okay, it's just the police car."

You can't go along with the little bastard every time!

The place where Alina White sleeps is a remote and quiet cemetery on the outskirts of London, which is so old that few people come to it. Lestrade and Sherlock arrived first, and they saw from a distance the vehicle driven by the suspected murderer that Sherlock had seen parked on the side of the road. Lestrade took out his matching gun from his waist, he was going to wait until his subordinates arrived before going in, who knew that Sherlock had already run away while he was not looking.

Lestrade could only curse the words that started with F, and then hurriedly followed, he couldn't let the little bastard get hurt.

When he catches up with Sherlock, in front of them a lady in a long black dress sits in front of a tombstone, with a bouquet of bright red roses at her hand. She heard footsteps behind her, turned her head to look, and said with a smile, "Are you also here to visit her?" ”

"You're Lara White, and this is your sister, and the reason you're visiting her today is to tell her that the bastard who hurt her is dead." Sherlock's eyes swept to see all of her flaws, "You...... Sick, yes, that's why you choose to do it at this time, it's a very strict disease, it will make it difficult for you to breathe, so in the sewer you will have a period of time when you suddenly stop, where the footprints can prove your identity, and the strenuous exercise makes your body unbearable. ”

"Great reasoning, I really don't have much time left."

The woman stood up, patted the dirt on her body, and smiled at them, saying that she couldn't imagine that this person had killed three people just by looking at her demeanor.

"You want revenge, I guess everything has to do with Buck, I want to think your sister is a lover with Buck? Still too fond of Buck, Horton Buck must have asked her out, but he deceived her, and the young ones violently assaulted Alina, eventually leading her to collapse and commit suicide. The perfume on your body from more than 20 years ago doesn't look like you can afford it at all, so it can only be a gift, someone else gave you or a gift from Alina, I think Alina is more accurate. ”

Sherlock sniffed, he thought of a brand of perfume, which appeared in their era, but the price was not affordable for ordinary students, only a gift from someone else, and this person was a boyfriend in a specific way.

"You only started using it recently, so you want to remind yourself that you want to avenge her, and you slashed Horton Buck in the face thirteen times as a mockery of him, and at the same time, you think it's the atonement for your sister with his life, right?"

"Yes, it's a debt he owes."

She didn't deny it, "Lala" gently brushed the stone tablet with her hand, and then said: "Mr. Detective's reasoning is very wonderful, but you are wrong about one thing, my name is ...... 'Alina', I am Alina, and here is my little sister who is sleeping quietly, Lala." ”

"I knew it, I knew it was wrong."

Sherlock thought that there was a sense of disobedience in this case, and now there is no more.

Alina White glanced at them and slowly told a story, a story about the sins of more than twenty years ago.

The person who fell in love with Horton Barker back then was Alina, they were a couple that everyone envied, although there was not much affection for free love in that era, but Alina's girlish feelings told her that she was in love with that person. Horton was also generous, and he gave her perfume, which was a luxury in those days. They get along well, until one day Horton says he's going to ask her out to surprise her, and her more bubbly sister comes up with a little game, and the two of them look almost identical, so the naughty Lara wants to know if they can get out if they swap Horton.

She agreed.

But Holden is not a good man, and he betrays Aliana's trust by telling his two brothers to introduce them to "Aliana" as if they were showing off, and by the way, he also offers words of shared enjoyment.

So, as Sherlock and they knew, "Alina" or Lara had a breakdown, and she couldn't stand what had happened to her, so she chose to understand her own life.

After that, they had a quarrel trying to get Horton to die, but the power of the Buck family was not what they imagined, they failed and the heartbroken parents took her away, she continued to live under Lala's name, and after twenty years of her parents died, she returned to London, it was so coincidental that such a big London just let them meet, and Alina, who was diagnosed with heart disease, saw that they were well-dressed and hated, so she did it after the plan was made.

Avenge Lala is also for them to atone for their sins.

"Miss Lara White, perhaps we can go back to Scotland Yard and listen to your story."

Lestrade heard chirps from near and far, and thought the game was over, and whatever the reason she had to pay for what she had done.

Just as Reintrid stepped forward, Alina took out a handful of □□ from the back of her skirt and pointed it at Reestrid, "I advise you not to move. ”

She already has so many lives on her hands, and she doesn't care about one or two more.

"Miss Alina, are you doing this just to get revenge on them? Or have you been reluctant to rely on them to atone for your sins? ”

Sherlock points out another meaning of the story, believing that in addition to the three brutes, there is one person to blame for Lara's death, and that is the real Alina.

"You're right, I've always been condemned in my heart, and I'll never forget Lala's last expression, and it's me who should have suffered this qiē, so there are actually four people who should atone for Lala's sins."

She pulled the insurance and pointed in Sherlock's direction.

Lestrade pounces Sherlock as Alina pulls the trigger.

Then I heard a "bang" -
