Dear Archimedes 4 Archimedes and cipher

  "911, I found my roommate killed, please..."

  "The word 'slaughter' hung in the air, its tone carrying an inexplicable chill."

  Zhen Ai was stunned. Indeed, such a bloody scene was not murder but slaughter, but she didn't care about him and continued to report the police according to her own idea.

  She put down the phone and gently closed the door, standing at the entrance without going in or out.

  "Why didn't you call an ambulance? How did you know she was dead?" Yan Suo was wearing gloves and examining the deceased.

  At this time, he still knew how to interrogate her, which was indeed his style.

  Zhen Ai didn't think this was abrupt and calmly said: "From the bathroom to the dormitory, at least 2 liters of blood."

  "Your eyesight is quite good." He said ambiguously, "So precise, you understand human anatomy?"

  Zhen Ai's heart skipped a beat, her black eyelashes drooped, covering her shiny eyes, and she calmly replied: "I don't understand."

  The few seconds of surprise and hesitation were not difficult for Yan Suo to analyze. The answer was ——

  Tell lies.

  His response was: "In the time it took you to react, the Earth has already traveled 74,475 meters around the Sun."

  Dislike her slow reaction, Zhen Ai this time simply did not react.

  He pressed his fingers against the neck of the corpse, staring at the wound and saying slowly: "A small fruit knife, with a short but very deep blade, accurately cutting off the carotid artery. The murderer was really lucky."

  Zhen Ai could tell that his last sentence was sarcastic, so she didn't comment on it.

  Sure, here is the translation:

  "As expected, his next sentence was: 'However, to make a logician believe in luck, this abstract thing...'" His tone actually didn't have any hint of amusement.

  The deceased, Jiang Xin, was dressed neatly, but his shoulder-length hair was wet. His hands were spread out on the ground like a ghost's. There was a long trail of blood from the bathroom to the room.

  The forensic doctor squatted on the spot and examined the deceased, with pinch marks on both sides of his neck and faint bruises on his shoulders, which had not fully appeared due to the short time since death.

  He stood up and scanned around with his eyes, but didn't move, probably afraid of disturbing the scene.

  A very ordinary double room, on the left is Jiang Xin's bed and desk chair, with many things, mainly clothes and accessories, looking quite valuable; The dresser is filled with all sorts of perfumes and cosmetics, almost no space left. There is also a calendar with many circles drawn on it, showing the owner's busy daily life. A jewelry box was knocked over on the floor, brooches, hairpins, earrings and other things scattered all over the floor.

  On the right side is Zhen Ai's bed and desk chair, very clean and simple. On the desk are several rows of popular media books. On the bed hang a few expensive and sexy clothes, nothing else.

  Yan Yu's gaze fell on the dressing table in the middle of the river and suddenly asked: "How many jewelry boxes does she have?"

  Zhen Ai gazed at the scattered decorations and said casually: "One... I don't know."

  "There's a problem with this," said the meticulous logician, furrowing his brow. "If you answered 'one', why say you don't know? If you don't know, why make an educated guess?"

  Zhen Ai: ……

  He glanced at her and didn't ask further.

  The window beside the dresser was half open, and in the afternoon a small amount of rain and snow had fallen on this side, leaving two very clear dry marks on the dark-colored table.

  Zhen Ai also saw it, a square and a rectangle. The rectangle was exactly the same shape as the decorative box on the ground, while the square... She looked around and there was no doubt that something was missing from the scene.

  Just thinking of this, Yan Su muttered to himself: "Two things are missing."

  Zhen Ai frowned, what's wrong?

  Huh, how didn't she realize?

  I was a bit curious and wanted to ask, but I thought it's better not to interfere. Besides, looking at Xun Yu's face, it clearly says "Do Not Disturb" in big letters.

  He looked towards the bathroom, where splattered bloodstains were on the wall, the scene of the first case. In front of the dresser was a trail of dripped bloodstains. Why had the deceased been dragged into the room and made such a mess?

  The deceased's clothes were neat, but his hair was wet and dripping with water, why?

  The most crucial point is that after shedding so much blood, the murderer's body can't possibly not be stained with blood. So how did he walk out of here calmly?

  He turned his head to look at Zhen Ai by the door and said indifferently: "If you feel scared or uncomfortable, then leave."

  Zhen Ai said: "I don't think so."

  She narrowed her eyes slightly, and that expression seemed to be challenged. After looking at her for a while, she turned her head away, and her tone became unquestionable: "From the moment you came in until now, you've been holding your hands. This is a self-soothing posture in your subconscious mind, so..."

  He paused for a moment and concluded: "No need to deceive me."

  Facing his questioning, she neither admitted nor denied, but said indifferently: "Oh."

  She fell silent, with a somewhat strange expression. Her response didn't conform to the rules of effective dialogue in linguistics at all, her words were disconnected and illogical.

  According to linguistic concepts, this conversation cannot continue.

  So he didn't plan on continuing, but after a while, he said: "Actually, I think you're disturbing me by standing here."

  Zhen Ai raised her eyes and looked at him: "I didn't move or speak."

  "Breathing has sound."

  Zhen Ai went out and opened the door.

  Evan arrived soon after, followed by the police from the jurisdiction. It was then that Yan Su came out of the room and allowed forensic personnel to start collecting bloodstains, footprints, and other evidence.

  Among the people coming in was a very pretty Latin American female forensic pathologist with wheat-colored skin, natural wavy hair and a sexy figure. Seeing Yan Suo, she smiled without smiling: "Hey, weirdo!"

  He glanced at her and ignored her; Owen was very enthusiastic.

  The female forensic expert is called Eva Diaz, Owen calls her Eva, but the words refer to her as Sergeant Diaz.

  It's clear that Yan Suo and Eva are familiar with each other.

  Eva was about to enter when she saw Yan Suo's light brown eyes scanning her up and down without any expression. She crossed her arms, tilted her head, and asked provocatively: "What? Are you guessing where I went today and what I did?"

  "It's not guessing, it's observation and reasoning." Xian Yu corrected her wording, saying, "You didn't go home last night and stayed at a man's place. After sex, if you don't take a bath and change your underwear, the probability of inflammation or infection will increase 3-4 times."

  Eva smiled with gritted teeth: "Thanks!"

  "No need."

  Eva walked straight in with her head held high.

  Zhen Ai peeked through the gap in the door, and saw that the room was shrouded in darkness with the curtains drawn. Under the faint purple glow, the scarlet bloodstains were particularly striking. As she continued to look, Owen's body blocked her line of sight, and he patted her shoulder: "Ai, don't be afraid."

  Zhen Ai nodded.

  "Some people called Yan Suo. This time it was a black-haired and yellow-skinned police officer, speaking all in English, looking very familiar with Owen."

  Her name tag read Jasmine Van De Bilt, and Zhen Ai found it strange that a yellow-skinned person would have such a traditional and old-fashioned English surname.

  The Vanderbilts have been a very active family in politics for hundreds of years. Is she married into the family? Looking at her age, around 23, Americans usually get married late, it's really hard to say. Did her mom marry into this family? That doesn't seem right either. Vanderbilt's appearance has very obvious mixed-blood characteristics, deep eye sockets, light-colored pupils, high nose bridge, thin lips, black hair, white skin, and facial features that are as three-dimensional as plaster.

  Jasmine doesn't have the slightest mixed-blood look, but rather a very typical Eastern face, with a flat nose, thin eyebrows, low forehead, long and narrow eyes, and skin that's even darker than average yellow people. However, her facial features are well-coordinated, making her look comfortable to watch, and when she smiles, two dimples appear, making her even more adorable.

  Jasmine has a lot of style, looking sharp and capable yet still approachable and innocent, with every gesture showing good breeding.

  But on this matter, Zhen Ai was very dull. From an early age to adulthood, she had almost no social interaction, so she couldn't quite understand the meaning conveyed by others' expressions or actions.

  She stood by and didn't interrupt. Jasmine also didn't notice her, she admired Yan Suo very much, after saying a few words, she asked for his opinion on the crime scene, wanting to hear his thoughts.

  But the lawyer refused, citing that the evidence collection was not completed, saying he only observed some things and had not formed any thoughts, nor did he want to say anything now to interfere with the judgment of the police officers.

  As soon as he spoke, Jasmine obviously appreciated him more; even Zhen Ai couldn't help but glance at him sideways, surprised by his principles, which turned out not to be a person who always showed off his intelligence at all times.

  Yan Yu raised her light eyebrows and met Zhen Ai's gaze, then calmly looked away.

  Jasmine looked at the scene and came out to discuss the case with Yan Suo: "It seems that something similar to a jewelry box is missing, could it be a robbery?"

  Xian Yuandong said, "It's not necessary to drag the victim from the bathroom to the room for robbery. It's difficult to operate and easy to leave footprints. Moreover, it was a stab wound, not a slash wound, the murderer had resentment in his heart."

  "Then I'll go check if there are similar cases, see if it's a series..."

  "Don't waste any more time." Xian Yu cut her off decisively, "Even if she was the target type, a serial killer would lure them away, not choose to kill in a fourth-floor dormitory. However, this murderer," he narrowed his eyes slightly,

  "With means, calm and prepared, this time's anger is vented, next time... it's very likely to develop into a serial killer in the future."

  Jasmine was puzzled in her heart, and didn't know how Yan Suo had figured out the murderer's personality. Although she was curious, she ultimately didn't ask, but instead nodded: "It's just like I thought."

  He walked to the door of the room and said to the forensic personnel inside: "There is an irregular blood stain over there, which looks like it has been wiped; it seems that something pressed down on that blood spot, take a closer look; check again the rectangular mark on the dresser, does it contain any adhesive residue." The on-site personnel followed his instructions and went to collect evidence.

  After everything was done, the deceased was carried out.

  When Eva came out, Yan Su added a sentence: "Check the lungs of the deceased."

  At this time, a police officer asked who made the emergency call and if they could return to the police station to assist with the investigation.

  The first person to discover the scene and report it often has a high degree of suspicion.

  He pointed at Zhen Ai without hesitation.

  The police officer was surprised: "Aren't you the deceased's roommate?"

  Owen knew that Yan Yu was an acquaintance of the police station, so he quickly said: "She is with me."

  Yan Yu looked at Ou Wen for a moment, then said to the police officer: "She came with me." After a pause, he added, "But before we arrived at the scene of the crime, I was only with her for less than 5 minutes. From the bloodstains, it can be seen that the deceased has been dead for more than an hour, so it cannot be used as an alibi."

  This cooperative appearance is a model good citizen.

  Owen looked at him speechlessly and instructed Zhen Ai: "Ai, I'll inform the lawyer. If you don't want to speak, you can say nothing."

  Yan nodded: "The lawyer Owen found for you must be the best."

  Owen continued to stare at him silently, you turncoat, which side are you actually helping?

  The Vanderbilt family in this chapter is fictional because it's hard to write about the Kennedys, Adams, Roosevelts, Bushes and some other real families.
