On the basement floor of the Hirano Police Station, a quarter of the gun store is a gun store, which is stocked with a certain amount of guns, ammunition and police equipment, which can also be used by police officers to store and maintain firearms, while the other three-quarters are all warehouses, which are used to seal past case files and evidence.

The wind is gusting here, the air is cold and humid, the silence is silent, the walls are a little slippery to the touch, after all, the next floor is the temporary morgue of the police station, which always feels haunted, and even the lights are dim as if they have been smeared with a layer of human oil, revealing a miserable yellow.

"This is it, this room and this room, the case files from eight years ago are all in it." A blue-hat staff member in the identification class pointed to two rooms the same size as ordinary classrooms, signaling that Takeshi Nanahara and the others could take care of themselves.

Well, it's a little hard to believe that the staff of the Blue Hat Identification Division, who often walk around the crime scene, are all underground creatures, and when they are not on duty, they work in the basement of the police station, doing all the chores related to criminal cases, from autopsies, managing and maintaining guns, to storing files and evidence, they are all handling them, and even the identification section in some places is also responsible for raising dogs - the Hirano Police Station does not have search dogs, if there is, the work of feeding the dogs is also theirs.

Kiyomi Ruri bowed and thanked him, watching curiously as the blue hat left, finally solving a mystery.

Generally, there are blue hats everywhere at the crime scene, all kinds of taking pictures, extracting fingerprints, collecting evidence, and carrying corpses, but when I came to the criminal department of the police station, I couldn't see any of them, as if as long as there was a crime, these people would come out of the ground, but now it is finally clear that these people really came out of the ground, and people usually do not work above the ground at all.

Nanahara Wu didn't care about these idle things, looked at the dusty door with disgust, took out the mask and put it on, stabbed Kiyomi Ruri, and signaled her not to be in a daze, and quickly opened the door for his "blind detective".

Kiyomi Ruri came back to her senses and quickly opened the door, but as soon as the door opened, a large cloud of dust fell, and she couldn't help but sneeze.

Taiji Okuno and Hidakashi frowned, waved their hands to disperse the dust, and when they entered first, they turned on the lights, the wattage was lower than that of the aisle, but it was still bright.

"Let's get started, find out all the cases that involve murder and wounding, especially the cases where the victim is a woman and have not been solved." Nanahara Takeshi entered the door and took a covert glance to determine that the file management of the Hirano Police Station was very stretched, and it was not at all arranged according to type and time waiting for people to come and see it like in the library, but it was full of large and small cardboard boxes, piled up horizontally and vertically, and it was already considered due diligence to be able to label you.

But then again, before computers and the Internet were not popular, it was okay to be able to save files like this.

The Tokyo Metropolitan Police Department has also had a case review before, but it turned out that the initial investigation files, interrogation records, and exhibits disappeared after just over a year, and the one that can still be found in the Hirarano side is eight years old, and it is already considered to be able to pass in this police circle.

When Taiji Okuno, Hidakashi and Ruri Kiyomi heard his order, they immediately took action, checked the labels one by one, opened them when they were involved in killing or hurting people, judged whether they had been detected and the gender of the victim, and first helped him filter them, and handed them over to him if there was a problem, and asked him to carefully "grope" and check them.

There was a lot of dust, and when I turned over the box, there was even more, Kiyomi Ruri had been sneezing, and when he found an uncleared case of wounding, he moved out for Nanahara Takeshi, seeing that he was hiding outside the door, it was fine, and he couldn't help but complain: "You are comfortable......"

When she becomes a police officer, there will definitely be a major reform of the police station, requiring everyone to pay attention to daily cleaning, and if she has nothing to do, she will come down to check the sanitation work to ensure that the place is spotless.

Qiyuan Wuzheng rummaged through a box, and said angrily: "This is what you asked for, how comfortable we were at home, we had to be fooled into working for nothing, and now we deserve to eat ashes." ”

Qing saw that Ruri didn't fart, so he turned his head and went back to continue looking, there must be more than a thousand boxes in the two rooms, large and small, enough for them to be busy for a while - it's not that more than 1,000 people are killed in Hirano a year, and there are also a large number of thefts and violent cases.

Nanahara Takeshi also calmed down to do things, after all, he collected money, looked at one case after another, and wanted to find a case that had something in common with the "Tuesday Night Serial Murder Case", such as the same death from massive blood loss but not so many cuts, or being killed after hanging upside down, or only having blood taken away after killing, but he tossed until noon, he checked all the suspected cases, and did not find a single similar one.

"Maybe the murderer has imagined many times in his mind, so the modus operandi was stable and mature from the beginning?" Kiyomi Ruri is now a little gray man, her hair, face and hands are covered with dust, and she is a little frustrated to find that she has not gained anything, but she still actively gives her opinion.

"It really can't be ruled out." Nanahara Takeshi didn't waver, got up and paced and muttered, "But it's unlikely, there is a difference between imagination and reality after all, and it needs to be corrected, and it is impossible to remain the same, especially the first time it should be significantly different from the other times...... It should have been the time when he couldn't hold back his inner impulse, and it should have been the closest to his residence. ”

Kiyomi Ruri immediately pointed out the current situation: "But now I haven't found anything, what should I do?" ”

Taiji Okuno thought for a moment and proposed, "If this method doesn't work, then let's go to the scene of the crime and have a look?" The scene of the sixth case is still protected, and maybe Nanahara-san can find some useful information. ”

Nanahara Takeshi pondered for a moment and slowly shook his head.

He is not really blind, in fact, he has seen a large number of photos of the crime scene, and even the material of the rope and the way of knotting have been carefully analyzed, and no useful traces have been found - the most ordinary nylon rope, which can be bought anywhere, and the knotting method is an ordinary sailor's knot, and there are a lot of people who know it, except for the fact that the murderer can be judged to be a right-hander, the murderer has not left any significant features.

Therefore, there is no need to go to the scene again, and the character and identity of the murderer cannot be seen in a single forest.

He thought for a while, but he didn't think of any other breakthrough for the time being, looked at the other doors in the aisle, and said, "Let's look at the scene when it passes by, and first go through the cases from nine years ago and ten years ago." ”

At the very least, make sure that this path doesn't work, and then it's not too late to think about changing paths.

Taiji Okuno has no opinion, this group Nanahara Takeshi has the final say, but Hidakaji raised his hand and looked at his watch, reminding: "It's noon soon, do you want to eat first?" ”

"Then eat first, and we'll be busy after eating." Qiyuan Wu is not in a hurry, this case has been delayed for seven or eight years, and it is not bad for this time.

The four of them didn't want to climb the stairs anymore, so Okuno Taiji found a place for Nanahara Takeshi and Kiyomi Ruri to wash it briefly, and Hidakaji quickly went to get a bento, and everyone simply ate a little.

Kiyomi Ruri recognized it as soon as she saw the bento box, and said happily: "It's a bento made by Sister Yoshino." ”

Nanahara Wu tried the taste, nodded and smiled: "It's okay, I didn't cut corners." After speaking, he thought about it, and then instructed Kiyomi Ruri, "Go back and let her complete the order every Tuesday during this time, don't receive individual customers after dark, and take Xiaokui home early." ”

Although the interval between the murderer's crimes is extremely long, from the perspective of the last cycle, each time is about three months apart, but now I don't know who the murderer is, and I don't know what kind of stimulation he has received, what changes will occur, so I am not afraid of 10,000 just in case, how much better be careful!

He also counted on the Naokawa sisters to help him make money in the future, but he couldn't die.

"I know, when I send you home, I'll ride there, and let her treat Tuesday as a day off and do less business." Kiyomi Ruri agreed with a bite, but after taking a bite of food, he said thoughtfully, "You said that the murderer singled out Tuesday to commit the crime, will that day be his rest day?" ”

Nanahara Takeshi picked out the dishes that didn't fit into Kiyomi Ruri's lunch box, and said casually: "It's very likely, so I think Professor Hirakawa's criminal psychology portrait is not quite realistic, and the murderer should have a serious job and a certain regularity in life." ”

Taiji Okuno ate quite comfortably, and when he heard this, he raised his head and said, "Then do you want Professor Hirakawa to say something and let him correct it?" ”

Nanahara Takeshi shook his head and smiled: "There's no need, everyone relies on guessing for this kind of thing, and no one can convince anyone." For example, he may think that the murderer has serious paranoia, obsessive-compulsive disorder, or that Tuesday has a special meaning for the murderer, even if the murderer is autistic and has nothing to do at home, he will still deliberately choose this day to commit the crime, I can't deny this possibility, so I can't argue right or wrong until the murderer is caught. ”

For him, it's not bad for Pingchuan Shi to go to check for mental illness, if he can find the murderer, it will be convenient for him to go home, and there is no need to fight for who to guess.

Kiyomi Ruri thought for a while, and asked curiously, "Then what kind of work will be closed on Tuesdays?" ”

Hidaka thought for a moment and said, "Tuesday has a lot of work off, such as the catering industry and tourist attractions, and it is usually the busiest on Friday night and weekend, Monday to take inventory and replenish stocks, and Thursday to prepare for the next three days of heavy traffic, usually the rest day is placed on Tuesday and Wednesday. ”

Taiji Okuno added, "Some factories have production lines that can't be stopped, and employees are assigned to regular breaks at different times of the week, and some of them have long Tuesday offs. ”

Kiyomi Ruri was disappointed, so there were too many people who took a break on Tuesday, and it couldn't be a breakthrough in the case.

She took two mouthfuls of food, thought about it again, and asked again: "Why did the murderer hang the victim upside down, force the victim to keep his eyes open, and take away the victim's blood, could it be that some kind ......of religious ritual is involved?"

As she spoke, she suddenly had a flash of inspiration, reacted, and directly shot the case, and said excitedly: "Wait, I seem to know why the murderer did this!" ”

Nanahara Takeshi looked at the lunch box that was almost overturned, and said dissatisfied: "What kind of nervous ...... are you having while eating well?"

Kiyomi Ruri didn't care if he was happy or not, and said excitedly: "Didn't you find that the victim fits the image very well?" ”

Damn, I can finally think of it first, maybe I can directly lock in the victory, and it can play a huge role in catching the murderer!

I really didn't expect it, I suddenly improved, I started to get smarter, and I could think of clues that I couldn't think of before!

Nanahara Takeshi straightened the lunch box and said strangely: "Isn't it like the upside-down hanged man in the tarot card, what are you excited about?" ”

Kiyomi Ruri was stunned, and hesitated: "Yes, it's the upside-down hangman, you ...... You've seen it for a long time? ”

"Brain-made." Takeshi Nanahara pointed to his sunglasses, indicating that he was still blind and couldn't see it, "You were still playing mud when I played tarot cards, and I felt a bit like it when I heard you describe the photos of the scene last night, but is it important enough to jump?" ”

"Doesn't it matter?" Kiyomi Ruri became more and more hesitant, feeling that this should be a big discovery in reasoning.

"If it matters, what does this prove, and what help does it help to find the murderer?"

Kiyomi Ruri hesitated, sat down slowly, lowered her head and continued to eat.

Damn, it seems that it can only prove that the murderer is a psychopath, but he has been killing innocents indiscriminately, he is a psychopath, it seems that there is no need to prove it, it still doesn't help to find him - tarot cards are too popular, yesterday she also saw a few girls in the class get together to take tarot cards to divinate love fortunes, clear about the symbolism of hanging people, in this book is not rare at all.

This case is so tricky, I can't find a clue at all!

She honestly finished eating the lunch, and went to the "warehouse" to work as a coolie, for the "justice" in her heart, she really worked hard, and while working hard, she was still thinking hard about where else to start with this case.

The murderer didn't commit a crime eight years ago, and she didn't have hope for nine years ago, and she was thinking about it all the time, but when she opened a box, a photo of a corpse with wide eyes suddenly appeared in her eyelids, even if she was not small, she was still scared and trembled.

She hurriedly took a look at the details of the case in the dim light, her heart trembled again, and her voice was dry: "That...... I seem to have found the case you're looking for, that is...... It's, uh...... It's not necessarily ...... found."

The corpse in the photo is a rabbit hanging upside down, covered in blood, and even if it is not a human being, she still thinks the modus operandi is a bit like the "Tuesday Night Killer".
