Detective Bennet [Comprehensive novel]

"I hear there's been a case of dismemberment near Baker Street."

After entering the house, Mycroft bluntly stated his intentions to the two, "I'll drop by to ask about the situation."

Sherlock: Walking slowly for four or 10 minutes after get off work is not in line with Mycroft's daily habits at all.

Could it be that his lazy brother finally realized the dangers of sitting for a long time and started to try walking and fitness, so he stopped by Kelsey's house on Montague Street?

Haha, don't take it seriously, it's a joke.

Sherlock knew well why Mycroft had come so quickly.

Mycroft was the initiator of the old case of checking whether there were any deposits along the subway line. Before he got off work, he must have got the news of the dismemberment case.

At this time, Mycroft should be touched by a thoughtful younger brother.

The good brother in London understands righteousness and accepts the commission of cooperating with Scotland Yard to investigate.

Regardless of the erratic weather in the foggy city, I have traveled underground for three months to check whether there are vicious crime threats in and around the London subway.

"There are many plays."

Mycroft looked calm, even though no one spoke, he had already read Sherlock's expression.It's just that since when did the withdrawn younger brother become more and more good at acting?

In the past, Sherlock only played different roles in investigating cases, but now he brings more dramas to his daily life. It seems that life is not fun.

Kelsey only felt a look fall on her.

Kelsey's confused face: I'm not, I don't, don't guess.

Why was Mycroft looking at her inexplicably?She is weak, innocent, ignorant, and obviously has no relationship with the perpetrator.

"Another drama."

Mycroft quickly identified the source of Sherlock's change.When they meet a well-matched actor, the two of them will play together from time to time, and the originally boring life except for solving crimes will naturally become more colorful.

Moreover, the two people who play a lot are very good at using local materials, such as sweet tooth lovers who are worthy of admiration and love.

Mycroft looked towards the candy carton on the desk, for which he had come.

Before leaving get off work, I learned that there was a boiled human head and a box of old candy wrappers at the scene of the dismemberment case. If there is no accident, Sherlock will ask him about the origin of the candy wrappers.

However, the younger brother who acted quickly did not come to the door immediately.

At the moment, Mycroft guessed that Sherlock chose to find clues from the skull first, most likely going to Kelsey's house.Since it was he who proposed to check the subway line, today he took a rare walk and went to Montague Street to provide off-site guidance.

Unsurprisingly, the dynamic speculation about Sherlock was correct.

Unexpectedly, Sherlock actually talked about family fun with others.

Mycroft knew at a glance that they must have been talking about him before they opened the door.

Instead of simply stating that someone can provide clues to sugar wrappers, Sherlock published 'two or three great deeds of my brother collecting sugar wrappers'.

Is this wrong?

Of course, something is wrong.

Sherlock rarely chats with people, and even the occasional chat is limited to topics related to solving crimes.

For example, various trace detection methods, such as one hundred and eight different poisoning symptoms, at most it is which book is the most favorite.

Gossiping about household chores?

It doesn't exist at all.

Mycroft circled the two seated opposite him.

Unknowingly, Sherlock and Kelsey grew closer.It's hard to say whether it's good or bad, only one thing is certain, whether it's lucky or unlucky, both of them share blessings and misfortunes.

"Mr. Holmes, you are too timely. We are at our wit's end with the candy wrappers."

Kelsey interrupted Mycroft's thoughts, and he couldn't let him think about it, and God knew what he would associate with it.

Sherlock took the conversation, in time to focus everyone's attention on the new case. "My respected brother, you must be able to explain to us the origin of these candy wrappers."

Mycroft: Don't think I don't see you guys changing the subject.However, as long as there is no danger to his life, he is too lazy to ask about everything.

"These are candy wrappers from more than 20 years ago."

Mycroft took out the wrappers and sorted them. There were seven hundred and four wrappers in all, belonging to sixteen sweet shops.

""Little Daisy" closed down, "Donut" has no successors, and the "Three Bears' Mushroom House" family immigrated to the United States..."

For more than 20 years, the British capital market is in a period of rising and transitioning, and many old stores have disappeared in time.

Mycroft said goodbye to these old sugar wrappers, many flavors of childhood memories disappeared, only two or three surviving shops.

"Only these three are still there."

Mycroft moved the candy wrappers aside, and wrote down the names of the corresponding candy shops and their current business addresses one by one.

He added: "The candy wrappers in the box have nothing to do with high-priced candy shops. The flavors are mainly aimed at children aged seven to 13 in London. The sales years are concentrated between 1854 and 1857. Later, some changed the outer packaging, and some off-production."

"Also, based on the purchase of the smallest size of candies sold by the store each time, the per capita annual income of that family should not be less than fifty pounds if the amount of candies can be consumed within three years."

Mycroft also reminded, "The decomposed body was found near Baker Street. More than 20 years ago, it was the beginning of the construction of London's first subway."

Why bring up the subway construction?

Mycroft didn't elaborate further, and declined the invitation to stay for dinner and left first.

He would never tell the two of them the important reason why they dropped by here today.Walk three more streets, and a cake shop there will launch new products tonight!

Do the math.

Mycroft came down the stairs just in time for the new time of six o'clock at night when the cake was served.

Kelsey heard Mycroft's footsteps drifting away, and suddenly thought of something, but he still asked about the dismemberment case first.

"It is now known that the candy wrappers were old objects more than 20 years ago. The murderer buried the old candy wrappers and the deceased in the abandoned house. There is a possibility that more than 20 years ago, the murderer, the deceased, and the area of ​​​​the burial site were related."

Sherlock shook his head slightly, "However, the construction of the subway started more than 20 years ago, and there is another subway station on Baker Street."

Having a site means there was a demolition around Baker Street 20 years ago.

That is to say, near the burial site, the homeowners who are included in the scope of demolition will receive a compensation, and then the original residents and tenants will disperse to other corners of London.

For investigators, this is not good news.

More than 20 years have passed since the demolition of houses in an area, which undoubtedly made it more difficult to find out the source of the corpse and the relationship between the deceased.

Kelsey asked a key point first, "Is the abandoned old house where the body was found the first crime scene, or the scene of dismemberment? You should have checked it?"

Sherlock gave an affirmative answer, "Yes, we did a comprehensive investigation at noon, and used the blood testing reagents you know."

At noon today, one hour after the body was discovered by Lestrade.

Sherlock came to the abandoned house with the luminol reagent.

The reagent was synthesized more than 20 years ago, but one of its properties has never been discovered.

——It emits blue light when it is oxidized, so it can be used in the detection of blood phenotype.Even if a long time has passed, even if the blood content is very small, it can sensitively detect residual blood.

In early March, Sherlock was excited when he discovered this property of the luminol reagent.

Its pleasure is comparable to the discovery of the four blood types, which means that the tiny bloodstains at the murder scene will be invisible.

Several experiments followed to find out which substances could affect blood test results.

First, iron, ferrous alloys, horseradish, and hypochlorous acid bleach were identified as interfering substances that fluoresce similarly.

Second, excrement will also cause the same reaction. If there are animals infested, their blood and urine will also cause deviations in the results, but the two can be screened out by re-examination of other reagents.

So how to deal with the first disturbance, especially the fact that bleach will be used by the murderer to wipe away the bloodstains?

Have to give Kelsey credit for mentioning that the two fluorescences are produced at different rates.This can be used to identify a bleach reaction, or a blood reaction, and then retest for suspicious signs.

The only flaw is that it requires rich trace inspection experience to identify different reaction speeds.

However, rich investigative experience is the most difficult to master.

Sherlock can learn quickly, but Scotland Yard cannot be counted on.

He wondered a little, did Kelsey know about the blood test application of luminol reagent?Although I hadn't seen him use reagents before, he got a negative answer after asking.

Doubts still exist.

I don't know who Kelsey studied under, but there are such knowledgeable but unknown predecessors in the European continent.

Doubts are doubts, and will not affect the investigation of the newly emerging corpse case.

Dismemberment is bound to have blood residue.

At noon, Sherlock used the luminol reagent to check the abandoned house to make sure that there was no suspicious blood reaction in the house.

Combined with other traces, it can be basically determined that the abandoned house is not the scene of dismemberment, and it is very likely that it is not the scene of the first crime.

"The abandoned house where the corpse is buried is quite special. When the subway was built, the area was included in the demolition. The other owners have signed the agreement, but the owner who is far away in the United States has not been contacted."

In the afternoon, Sherlock seized the time to investigate the relevant information of the abandoned house.

After the construction of the subway was found out, the location of the exit had to be changed due to geological structure problems.The municipal government decided to turn the demolished land into a small green cluster.

"The construction of the green belt is not in a hurry, so after the owner returned to China, he failed to negotiate the demolition fee with the municipal government, and the family continued to live for more than ten years."

Later, the owner's family passed away one after another, and the distant heir in the United States wanted to sell the property he had acquired.

But the location of this house is special, like an isolated island hanging in the middle of the road, which is not conducive to high-priced sales or rental.

In addition to inheritance tax and other issues, the house has been vacant for four or five years.

"According to the current situation, it is preliminarily estimated that the deceased was killed three or four years ago, and the door lock of the abandoned house has no signs of damage."

Sherlock pointed out, "The murderer probably came prepared and knew that the house had been unoccupied for a long time. He knew the lockpicking skills, or got the key for the abandoned house, and did not leave any suspicious traces such as footprints."

There are currently three basic problems.

Who is the deceased?Where was she murdered and mutilated?Why did the murderer choose to bury his body in an abandoned house?

The nature of murder and dismemberment are not the same.

Kelsey's murderousness skyrockets from a Criminal Minds standpoint.The victim's head had been boiled, leaving only the skull.

Afterwards, the dismembered body of the deceased was buried in the soil, and her boiled head was hidden in the attic. No matter how you look at it, the murderer did not choose the hiding place at random.

"Come on step by step. I will restore the head of the dead as soon as possible."

Kelsey said and was about to go out, "Go buy related materials first, clay, plaster, etc., and now I can catch up with the store before closing."

"Let's go together." Sherlock suggested, "There is a restaurant next to the material store. Let me invite you tonight. Thank you for your willingness to restore the head."

Kelsey nodded and walked out of the room, remembering the speculation about Mycroft just now. "By the way, when you go to the material store, you will pass through a cake shop. Did you know that new chocolate-related cakes will be on sale at six o'clock tonight."

Sherlock was taken aback for a moment, and Kelsey didn't look like hinting that he wanted to buy a new cake.

In the next second, he realized that it was not Kelsey who was interested, but someone else who made a special trip for the cake.

Kelsey suddenly remembered a classic question that can be applied to Sherlock and dessert.

"Question, when Tom and Chocolate Cake fell off the bridge at the same time, which one would Mycroft choose to save first?"
