dear archimedes

Chapter 15 Pipa and Nautilus (5)
When he said this, he didn't lift his head, but meticulously wiped the palms and backs of her hands, between his fingers and nails.

Zhen Ai didn't move, Mumu looked at his downcast eyebrows.He was so serious, and his movements were so gentle and meticulous, as if he was treating his most beloved books.

The soft material of the handkerchief, mixed with the cool running water, and the calm temperature of his palm all gathered in Zhen Ai's palm, making it a little itchy.The cool feeling slowly spread to the apex of my heart, itching even more.

Since she was a child, no one has washed her hands, including her mother.At that time, mother was standing by the sink with folded arms, watching little Zhen Ai standing on tiptoe on the bench, rubbing her little hands under the faucet.

She was in a trance: "When I washed my hands before, my mother said next to me that it takes 21 seconds to wash my hands."

Yan Su didn't raise his head: "Your hands are too dirty, you need to wash them for a dozen or 21 seconds."

Zhen Ai remained silent and fell into deep thought again.

She once saw Taylor washing Jiang Xin's hands at school, he surrounded her from behind, his light copper-colored hands rubbed Jiang Xin's white and tender hands affectionately under the transparent water.The two giggled.

The water droplets are shining with the sun's light, which is very beautiful.

At that time, she thought inexplicably that Taylor often played basketball, and his palms must have many calluses, which were rough but very textured, and that was a boy full of vitality.

But now, on the green lawn, the thin water flowed down, and the hands that overlapped with Zhen Ai were white and slender, with well-defined joints and toughness.

Zhen Ai stared blankly at him holding her in his palm, he carefully wiped away the mottled blood between her fingers, he and her fingers intertwined...

Her face gradually became hot.

But just like him, he still does this kind of action cleanly, without any hint of intimacy, just pure care and love.

Her beating heart gradually calmed down again.

It seems that he always has the power to calm people's hearts.

Zhen Ai settled down and asked, "How did you create a portrait of this unknown person who threw the bomb?"

"Part of it is based on the foundation of the predecessors." He was sincere and earnest, without any appearance of claiming credit or asking for credit,

"Such as mental patients, sadists, PTSD post-traumatic syndrome, serial arsonists, bombers, all have criminal portraits drawn by predecessors based on experience."

"Really?" Zhen Ai was curious, "So in the police system, there are general portraits of different types of criminals, such as serial killers?"

"Well, the FBI came up with a classification in the 80s, organized serial killers, and unorganized serial killers."

Zhen Ai speculates: "The mentally ill belong to those who have no organizational ability?"

Yan Su was carefully rubbing away a clotted blood on the back of her hand with the belly of his thumb: "In addition to the mentally ill, there are also murderers with severe PTSD post-traumatic syndrome. Both of these belong to the ability of disorganization.

Because their reasoning and social functions are relatively slow, it is easier to judge the scene of the crime——

Impulsive, not deliberately choosing victims, not bringing criminal tools, not cleaning up the scene after committing a crime. "

"What about organizational skills? For example, arsonists, isn't fire the most difficult to collect evidence?"

He's effortless: "94% of arsonists in the U.S. are male, 75% are white, young, between 17-27 years old. Bedwetting in childhood, difficulty with the opposite sex, low self-esteem. And the tactics will escalate, Arsonists eventually turn into serial killers."

Zhen Ai is silent.

As Yan Su said, behind this item of data is the accumulation of countless police officers and portrait artists, and it is only then that the outline of the criminal is outlined stroke by stroke over the years.

Thinking about it this way, this is the gathering and cohesion of the forces of justice from generation to generation!

Those who stick to justice never walk alone!
A trace of warmth surged through Zhen Xinxin, and she returned to the original question: "Then, where is the person who dropped the bomb?"

Yan Su was lowering his head, and gently wiped Zhen Ai's thin nails with water.Her fingertips were itchy, and she shrank slightly, but was caught by him again.

After a long while, he said: "Bombardiers are generally driven by three reasons, terrorist attacks, political goals, and personal grievances."

"Terrorist attacks will choose places where crowds gather like the subway or Times Square. As for political purposes, it is better to go to government agencies and military buildings."

"Smart." Yan Su curled the corners of his lips, "I really like people who think independently, although only occasionally have a flash of inspiration."

Zhen Ai: "..."

"About the bombardier, is there any data?"

"Well, the FBI profile of bombardiers is - 98% male, loner, history of sabotage. 50% of bombardiers blow themselves up, and some blow themselves up while planting bombs die."

Zhen Ai had a black line: "It's really thankless, stupid human being."

After hearing this, Yan Su smiled slightly, and said again: "On the contrary, people who make bombs are usually smarter. Of course, those who mix graphite and sulfur at will and blow themselves up are excluded."

After the joke was over, he continued: "A bomber driven by personal grievances, his purpose is to vent his anger and murder, and the bomb is his tool. Therefore, he will accurately select the target. Therefore, the location and crowd of the explosion show that His grievances and identity."

Yan Su glanced at the chaotic campus after the small-scale explosion, "He has lived in this environment for a long time, but he is always ignored by the people here. The explosion is his emotional outburst and his way of attracting attention. At that moment,
He was saying to the people on this campus: Look, here I am, making my grand entrance. "

Zhen Ai's heart trembled slightly, how distorted is that person's psychology, that he insisted on proving his existence in such a way?

"That's why you think the bomber is a student or a staff member of this school. So... he was randomly selected for this bomb?"

"No. Among these people who ignored him, there was always one or a few that particularly touched his nerves." Yan Su held her wet little hand, feeling that it was soft and boneless, soft and slippery, much softer than his The parrot at home is easy to touch, even better than Mozart and Elvis.

He settled his mind and said briefly, "This is the first bomb he has put into use. He needs to experiment and divert the attention of the police."

Zhen Ai frowned, thinking clearly:
"It wasn't just an emotional outburst, it was an orchestrated murder.

Killing indiscriminately is, of course, safer and safer than killing by targeting the enemy, and it is farther away from the sight of the police.As the bombings continued, among the countless victims, there were always a group of people he really wanted to kill.But at that time, how would the police know who his real target was?If the real target cannot be found, it will be difficult to find the real murderer. "

Yan Su seemed to bend the corners of her lips, she was so smart and cute.

She finished speaking spontaneously, and smiled suddenly: "Fortunately, there is you, you will be able to stop him, right?"

Yan Su was so trusted and flattered by her, his face froze slightly.Thinking back, he unknowingly talked to her a lot, but she not only listened with gusto, but also understood everything, and was able to keep up with his rhythm and communicate with him, which was really special.He gave an inarticulate "um" and silently decided to wash her hands again.

Zhen Ai fully participated in the reasoning, and didn't realize that her hands had been washed clean long ago: "Then he is organized and perfectionist, which can be seen from the structure of the bomb?"

"That bomb is already very fine for an ordinary bomber. He also has a mercury balancer. He is very imaginative and creative, and he regards his work as art."

Zhen Ai was sweating coldly. A person who can study murder weapons as an art is indeed perverted and terrifying.Such a person really can't stay long: "Then how do you know the suspect is in your photo?"

"The bomb is a very lethal and destructive weapon. It is a combination of wisdom and supernatural power. The more dangerous the production process, the more extraordinary the recognition and enjoyment brought to the maker at the moment of explosion. Hundreds of thousands Hours dance with danger, will he give up the moment that finally comes in handy?"

Zhen Ai nodded with complete understanding: "So he will wait at the scene to watch the explosion."

Yan Su was taken aback by these words, he overlooked a detail!
He took out his mobile phone and called Blake regardless of whether his hands were wet: "The scope of the suspect has been narrowed down. He has been at a certain cultural booth on that street. In this way, he can always observe the bomb on the steps without being caught." Anyone doubts."

After finishing speaking quickly, he hung up the phone, leaned over to hug Zhen Ai, and praised: "Smart girl."

Zhen Ai was hugged by him suddenly, his broad and tough embrace was full of a man's smell, which made her almost upset, but luckily it was only for a short moment.

She smiled shyly, glad to be able to help him.

"Actually, there is another possibility." Yan Su let go of her, "Maybe it is those doctors or policemen who want to satisfy heroism and play the role of rescuer, but considering 1. They don't have enough independent time, 2. The amount of explosives Too big, so ruled out."

"If it's a policeman, it's better to shoot directly; if it's a doctor, it's better to just release the virus..." When Zhen Ai said this, her heart was shocked and she quickly shut up.

Yan Su didn't care, turned off the water pipe, wrung out the handkerchief, and dried her hands carefully.

Only then did the two get up to watch the surveillance video.

Just as the bomb expert at the police station was about to leave with the bomb fragments, Yan Su squinted his eyes and suddenly called to stop: "Wait a minute."

He picked up a fragment in the expert's hand: "What's the matter with the notch in the middle?"

Expert: "It's not left by the explosion, it should be the imprint left by the maker. Generally speaking, the person who made the bomb regards it as a work of art, and will leave exclusive symbols inside the bomb. They are all very simple, and no information can be seen .”

Yan Su raised his eyebrows noncommittally, and asked, "What symbols are the fragments spelled out?"

"Should be a triangle with a straight line at the top."

Yan Su thought for a while, and continued walking with his long legs. While motioning for Zhen Ai to follow him, he took out his mobile phone and dialed: "Officer Black, the bombardier is likely to be wearing white clothes today."

When he took up the thread, Zhen Ai asked: "Why is he wearing white clothes today?"

"There is a straight line at the top of the triangle, and this figure can be viewed upside down."

Zhen Ai recalled the speech that had been made several hours ago, and immediately said: "That is the shape of a cup."

"Smart." Yan Su smiled imperceptibly, satisfied that she listened carefully to his speech, "That's the shape of the Holy Grail."

"You mean he is religious?"

"Not necessarily, but at least he has a good understanding of the doctrinal stories and agrees with them. Considering his silent, strict and eccentric character, such a person will definitely abide by that unwritten rule."

"That rule..." A light flashed in Zhen Ai's mind, "After Labor Day in September, don't you wear white?"

Yan Su glanced at her sideways, did not speak, but approved.

Come fall, don't wear white.

And now,
Zhen Ai looked at the fresh green on the side of the road: "It's the beginning of spring."

When he arrived at the school monitoring room, Yan Su pushed Zhen Ai to sit on the chair in the corridor, bowed down, and kept his gaze level with her: "Sit here and don't move, I'll come out right away, okay?"

Zhen Ai blushed slightly, she didn't understand why he suddenly coaxed a child's flattering tone?

If she didn't respond, he misunderstood.

He patted her shoulder quite seriously: "Don't be afraid, I will catch him soon."

Zhen Ai smiled: I'm actually not afraid.

Yan Shu went in to watch the video.

As the police officer said, the place where the bomb was placed was in the lower left dead corner of the video surveillance, and only one hand was seen placing a small box on the steps.The time is past six in the morning.

The blind spot... It is more certain that the perpetrators are school personnel.

What Yan Su wanted to watch was not the surveillance during this period, but the moment he walked out of the teaching building.

In the video, Zhen Ai followed behind him, and some people surrounded him to talk to him.At a certain moment, a man wearing a black wide hat appeared in the lower right corner of the video, and quickly walked towards Yan Su.

He crossed Zhen Ai's shoulder and stuffed a gift into Yan Su's hand, while his other hand put something in Zhen Ai's hat!
The man turned and left, followed by Yan Su, and ran out of the monitoring range.But Zhen Ai behind her made a strange movement, she looked in that person's direction and covered the back of her head.

The man pulled Zhen Ai's hair.

Yan Su frowned and continued to read.Soon, Zhen Ai chased after her.A few seconds later, a female student jumped and ran past the lower left corner of the video, and her sight exploded.

The crowd on the steps bloomed like fireworks.

Zhen Ai in the lower right corner of the screen turned around in surprise, and the girl named An Qi was covered in blood, and under the action of the shock wave at the moment of the explosion, she threw herself on her.

It looks like she protected Zhen Ai...

When Yan Su walked out, Zhen Ai obediently sat in her original position, motionless, but rubbed her hands together stubbornly.

He sat beside her, his face was not clear, but his voice was very soft, "What's wrong?"

She was startled, and remained still in embarrassment. It took a long time before she said, "It still smells."

Yan Su knew that she was talking about the smell of blood, but he didn't know how to comfort her.

Zhen Ai didn't seem to need it either, she seemed to be thinking about other things, she stared at her fingers, remained silent for a long time, and then said, "Have you already seen my identity?"

Yan Su wouldn't lie, he nodded, "You can see it from the first look."

"I should have thought of it earlier." Zhen Ai curled her lips and looked up at the sky.

Yan Su also looked up at the sky.

After a long time, Zhen Ai said quietly: "My fourth agent is called Harvey, from Alabama. He said that the name of Alabama comes from Indian, which means: I will overcome obstacles for you.

He said Alabama men had warriors in their blood.His name Harvey also means warrior.He is a fighter among fighters. "

I cut through the thorns and thorns for you;
To protect you, fight to the end.

"Every time he goes home, he checks the room first. That day he stepped on a gravity-sensing time bomb, and it exploded in one minute. I know that once the pressure is removed from the gravity time bomb, time will speed up exponentially. He He said that 1 minute may be shortened to more than ten seconds after he loosened his feet. He said: 1, we will run together without looking back..."

Zhen Ai lowered her head and let out a soft laugh, "Ah... how stupid I am."

Yan Su remained silent, imagining the situation at that time, the soldier must have watched her run a safe distance before letting go of his feet.

He would rather give her one minute than the ten seconds they spent together, and only give himself a few seconds.

"After running a long distance, I stepped on a dirty hand... He is a handsome guy who loves to clean... I rushed back, just like today, and pressed his chest wound. But he said:
Run, Kim, please, Run! "

At that time, her name was Kim.

Zhen Ai looked at the fluorescent lamp on the top of the corridor, and let out a deep breath.

Yan Su's pupils were dark, unable to see any emotion, and the arc of his jaw was tense.

He knew that this was just the tip of the iceberg of her dark past.

After a long time, he suddenly turned his head to look at her, and said firmly, "Zhen Ai, look at me."

Zhen Ai turned her head to meet his light brown eyes, not knowing why.

He said in a deep voice: "There is no doubt that you are the strongest and kindest girl I have ever met."

Zhen Ai's eyes widened in amazement, whether it was for her or him, this must be a very high evaluation.

She wondered if Yan Su wanted to comfort him,

It can be traced but is very certain.

After so many tragedies that ordinary people can't imagine, she can still stick to her bottom line and professionalism. She never mourns for her own experience, but can shed tears for the pain of her compatriots.

"I think, today, I saw your heart." He praised without hesitation, "It's very clean, very beautiful, and I'm very happy."

Yan Su smiled slightly: "No, I should say, I'm proud of you."

It was such nonsensical and illogical compliments that made Zhen Ai feel a lot of warmth in her heart.

He really doesn't know how to comfort others, but his approval and approval have made her feel brighter and full of fighting spirit again.

Since he praised him sincerely, she deservedly accepted it.

She didn't blush at all, and gave him a big smile to express her gratitude.

Her smile was sincere and innocent, with a little unaccustomed youthfulness. He was slightly stunned, and thought inexplicably for a moment, ah, yes, Owen is right, she really looks good when she smiles.

He was a little embarrassed, looked away, and asked again: "Have you told anyone about these experiences?"

Zhen Ai shook her head: "I'm not allowed to see a psychiatrist. Besides, I don't need it either. I can handle it myself."
