Summary:

[Stable daily update 4K] My name is Qin Ushu, I am 17 years old, I live in the Sakurasou area in the northeast of Chiba, I am unmarried, and I won the Oscar Merlin Award in the magic world at the age of 17.

I studied at Sobu High School, and because I only had to have two-thirds of the attendance rate to graduate, I often skipped classes and was late, and I didn't look like a student at all.

His main job is as a detective, and he often provides help in solving crimes for the Megure Police Department of the Criminal Investigation Section [-] of the Tokyo Metropolitan Police Department.

I was very popular with girls in school due to my status as a high school detective, but I remained single.

because--

Women only affect the speed of my reasoning!

Chapter 1 I am a high school student detective!

At ten o'clock in the night, the atmosphere in the spacious study room of a wealthy manor was deathly silent.

The space of less than seventy square meters was full of people. Counting those standing, sitting, and even lying on the ground, there were seven people in total.

Five of them were standing around a large mahogany desk. There was a book on the desk and a half cup of instant coffee that had been drunk and had gone cold.

On the floor beside the desk, a middle-aged man who looked like the master of the mansion was lying on the ground with a painful expression, his hands tightly holding his throat, his face pale and his mouth wide open, foaming at the mouth.

Theoretically speaking, you should call the police and call an ambulance at this time. If you have first aid knowledge on the scene, you can also provide emergency treatment.

But the fact is that this is no longer necessary.

Because the police had arrived a long time ago and everyone was already cold when they arrived.

Even the corpse was stiff.

Apparently been dead for a while.

"Mu... Mumu Police Department, so what is going on, who killed our master..."

The first person to break the silence and speak was an old man who looked like a butler.

Although he has gray hair, his back is still straight under his slim-fitting tuxedo.

The person who was called the Memu Police Department was a rather "robust" middle-aged man wearing a police uniform. He looked to be in his thirties. He had thick eyebrows, big eyes and good facial features. Although he had a round face, he gave people the impression of being... A sense of self-importance.

Hearing the old housekeeper's words, he pondered for a moment, then turned to look behind the desk...

To be precise, he looked at the boy who looked like a high school student sitting on the sofa behind the desk.

The young man rested his elbows on the table, crossed his slender fingers against his chin, and had a calm expression on his face that was not befitting his age.

"Brother Xian Shu, what do you think?"

"……Um."

After receiving the call from his brother's summoner, Qin Xianshu gave a slight greeting. He glanced at the body of the middle-aged man at his feet and said.

"Based on the clues collected so far, it can be tentatively concluded that the deceased was poisoned. There is an almond smell remaining in the deceased's mouth, so it is most likely that cyanide caused death."

"Based on the death characteristics of the corpse, the deceased should have died between one and a half to two hours after dinner. If the poison was mixed in the dinner, the poison would have taken too long to develop."

"And if the time to take poison is not dinner, then there is only... this cup of coffee."

The young man paused for a moment when he said this, and his eyes fell on the half-cup of coffee on the desk in front of him that was as cold as the deceased.

"Who made this cup of coffee?"

"is her."

One of the five people standing around the desk, a beautiful middle-aged woman who looked like a hostess, pointed out without hesitation to a young maid who looked about twenty years old next to the old housekeeper.

"Yes...yes, I have always been responsible for making Master's coffee."

Being suddenly identified at the scene of the crime, the young maid was obviously panicked and admitted hesitantly.

"B-but I really didn't poison the coffee!"

"Okay, I'll believe you for now."

Looking across the maid's face, Qin Xianshu said calmly.

"But considering that poison does not have to be put when making coffee, it can be plated on the bottom of a spoon, or smeared on the bottom of a coffee cup. Even if the drinking habits of the deceased are known in advance, it can be smeared directly on a specific unpopular location. feasible."

"So from my perspective as a detective, all three of you are equally suspect."

"However, there is currently insufficient evidence at hand for me to make an accurate judgment, so I need to collect clues. Please wait here. Please give me 15 minutes."

Having said this, he stood up from behind the desk, took out a pair of disposable white rubber gloves and put them on.

"This……"

The beautiful woman hesitated for a moment, seeming to be worried.

The Mumu Police Department understood it as soon as they saw it, coughed lightly and said: "Don't worry, Brother Ushu is also a long-term partner of our police. In terms of character, I, Mumu, can definitely vouch for him."

"All right."

Seeing that the police were talking about this, the beautiful woman could only reluctantly agree.

"Well, see you in 15 minutes."

After saying these words, Qin Sanshu opened the door and walked out of the study.

……

Leaving the study, Qin Sanshu walked down the stairs to the first floor.

The residence is quite large. If a blanket search is to be carried out, even if a professional team of police personnel is responsible, it will take at least a whole day. In just 15 minutes, only one room can be searched at most.

In this case, it is particularly important to narrow down the area where clues may exist.

But the good news is that whether it is an instant coffee powder bag or a coffee cup, its range of activities is basically in the kitchen.

After thinking about this, Qin Sanshu decided to start searching from the kitchen first.

It has been a long time since dinner time, and the kitchen sink is clean. There are no dirty dishes to be washed. All the tableware and kitchen utensils have been washed, filtered out and stacked in the cupboards.

There was a large amount of kitchen waste piled up in the big blue trash can. Qin Mianshu opened the lid and took a look inside. Judging from the smell and degree of fermentation, there was no doubt that it was all accumulated today.

And on the surface of the garbage, an empty instant coffee packaging bag lay quietly.

Qin Mianshu picked it up through the rubber gloves, held it in his hand and looked at it carefully, and suddenly frowned.

There is nothing wrong with the bag itself, it can even be said to be very new.

But therein lies its problem.

It's too new.

If a normal person makes instant coffee, they would first cut the packaging bag open and pour the coffee powder into the cup. In order to ensure that all the coffee powder is poured out, they would even rub the surface of the packaging bag with their index finger and thumb.

But there was no trace of rubbing on the empty packaging bag.

It seemed that someone just cut it open, poured out the coffee powder, and then threw it directly into the trash can.

Although instant coffee is not valuable, the dosage of each package is calculated, and the amount of each package is not too much. If some of it remains in the package and is not poured out, the taste will be more or less weak. .

It's a bit strange.

With this in mind, Qin Xianshu put away this "physical evidence".

At this moment, a faint aroma of coffee wafted over.

"Ok?"

Qin Xianshu followed the scent and looked toward the pool.

He immediately turned around and walked quickly to the pool.

With the light in the kitchen, the sewer of the sink was still dark. Qin Mianshu had to take out his mobile phone and turn on the flashlight function to take a look inside.

Under the illumination of his mobile phone, he saw many small pieces of black stains clinging to the internal folds of the water pipes.

Qin Mianshu didn't hesitate, picked up a chopstick from the chopstick holder hanging on the wall, put the head of the chopstick into the sewer, lightly stained it with a little black stain, brought it up, put it to the tip of his nose and smelled it.

"Is this...coffee powder?"

He thought for a while, put his chopsticks on the table aside, grabbed a thermos bottle, opened the stopper, and poured some boiling water down.

Not long after, a much stronger aroma of coffee than before came back, mixed with the smell of sewerage.

The smell isn't very pleasant, but it's enough to make you head over heels.

Could it be...

A fleeting thought drove him back to the trash can, holding the lower part of the trash can like Lu Zhishen uprooting a weeping willow, and then stood up suddenly to remove all the garbage in the trash can. Pour it out.

Whoa!

All of a sudden, various soups and water mixed with vegetable leaves covered most of the kitchen floor, piled high like a pyramid.

Qin Xianshu was very careful not to let these dirty things splash on herself.

He placed the empty trash can that was still dripping with water aside. Looking at the mess all over the place, the corner of the high school detective's mouth raised slightly.

"So it is."

……

The short quarter of an hour seemed as long as a whole year in the dull atmosphere.

In the quartz clock hanging on the wall facing the study door, the second hand ticked by.

When the minute hand rotated ninety degrees, the study door was opened from the outside on time, and the Qin umbrella that had left before returned.

His hands were empty.

"What, it's not nothing..." A trace of ridicule flashed on the beautiful woman's charming face.

But she paused before she could finish her words.

"You mean I didn't find anything?"

Qin Mianshu glanced over, turned his white-gloved left hand over, and found an instant coffee packaging bag in his palm.

The inside of the packaging bag was empty, without any coffee powder, and one end showed signs of being cut open with scissors.

The maid was stunned when she saw the packaging bag clearly: "This is the coffee I made for the master in the evening..."

"No no no."

Qin Sanshu raised his index finger and shook it.

"If this package is authenticated, you will find that there are no fingerprints on it at all."

"The one that really has your fingerprints on it should be this one."

After the words fell, Qin Xianshu turned his palm again, and what appeared in his right hand was an evidence bag with a self-sealing seal.

In the evidence bag, there was another instant coffee packaging bag with its opening cut and filled with various vegetable soups.

"What the hell is going on here?"

"If we just talk about the techniques, it's very simple."

Qin Sanshu put two empty instant coffee packages together and handed them to Officer Mumu.

"These are two instant coffee packaging bags that look almost exactly the same at first glance. Even the cut openings are almost the same. But if you look carefully, you will find that one of them is just cut with an opening, while the other is not only cut. The opening was cut, and there were traces of someone having injected it with a syringe.”

"syringe?"

"Yes."

Qin Xianshu continued.

"I will directly conclude that the prisoner injected a lethal amount of poison into each strip of a whole box of instant coffee in advance, and bought another box of instant coffee that has not been injected with poison so that he can replace it at a later time."

"He calculated that the maid would make coffee for the man of the house every night, and while the maid went upstairs to deliver the coffee, he would take the empty packaging in the kitchen trash can along with the rest of the poison-infused packaging in the box. The instant coffee was stuffed into the bottom of the trash can and replaced with new coffee bars that had been prepared in advance.”

"In order to perfectly accomplish this surreptitious operation without anyone discovering the secret on the package, the prisoner had to imitate the maid's technique and open a new package of instant coffee."

"However, due to time constraints and the fear of being discovered after committing a crime, the instant coffee could not be poured directly into the mouth with boiled water, so the prisoner had no choice but to pour the whole package of coffee powder into the sink and turn on the faucet to rinse it. At the same time, the empty packaging bag is thrown into the trash can, creating the illusion that the entire cup of coffee has only passed through the hands of the maid."

"Of course, actually it doesn't matter whether it's fake or not at this point."
