To examine Suzuki Sonoko's injuries, Lin Xinyi quickly rushed to the scene of the crime.

At this time, Detective Kudo had already rushed to the "arena" for more than a minute.

With his resourcefulness, this amount of time should be enough for him to deduce a lot of things.

However, when Lin Xinyi slowly walked into the women's bathroom and came to the scene of the murder...

He found that the great detective Kudo Shinichi was standing next to the corpse with a stiff face, his brows furrowed and he didn't know what he was thinking.

"How's it going, Kudo?"

Lin Xinyi faintly felt that it was not good.

You know, when he saw Kudo at the scene of the crime yesterday, the detective's expression was always "I understand" and "I understand again".

And now, Kudo Shinichi's reaction is:

“（╯＿╰）”

Kudo's gaze no longer seemed excited, but became solemn and serious.

He seems to have forgotten that this was a competition that he provoked himself, and even took the initiative to put down his posture:

"Mr. Lin Xinyi, you can also help take a look."

"Perhaps, you can see something from here that I can't notice."

A minute later...

Sonoko Suzuki gently compresses her injured neck with the ice cola she bought, and can't wait to return to the women's restroom where she just escaped not long ago.

She's not a high school detective, so naturally she doesn't like to see the bloody corpses and crime scenes.

But now the situation is different, after all, Lin Xinyi is investigating the case there.

Sonoko Suzuki was targeted by Lin Shinichi because of a report about Lin Shinichi's experience in solving the case, and as a fan of Lin Shinichi, she naturally won't miss the best moment for this idol to show her knowledge and charm.

"If it was Lin Xinyi, he would definitely be able to see through the truth faster."

"Hahaha... Kudo, that kid is going to be deflated again!"

Sonoko Suzuki instantly forgot about her long-standing friendship with Shinichi Kudo and stood on the side of her idol.

In this way, imagining the handsome picture of Lin Xinyi showing his wisdom, solving puzzles, chasing down the real murderer, and hanging Kudo, she rushed back to the scene of the crime in a hurry.

Then she saw that in the women's bathroom...

Kudo stood there in a daze, and Lin Shinichi also stood there in a daze.

Neither of them spoke, just thought quietly.

"What's wrong..."

Sonoko Suzuki felt the solemnity of the atmosphere:

"This case... Is there a problem? ”

Lin Xinyi continued to observe the scene thoughtfully, and did not react for a while.

But Kudo sighed lightly: "This case is a bit tricky. ”

"Huh?"

Sonoko Suzuki was a little surprised, or rather shocked.

She believed that Kudo might find the truth one step at a time, but she never doubted that Kudo would not be able to solve the case.

After all, after knowing each other for a long time, in her impression, there has never been a case that can bother this detective.

No matter what the case, as soon as Kudo Shin makes a move, the criminals will be like shells doused with salt water, revealing their true colors hidden under the protective shell.

But now, he was really stumped by the case.

"Could it be that even you... Can't you see through the murderer's modus operandi? ”

Sonoko Suzuki couldn't help but sigh in surprise.

"No... The murderer's modus operandi is easy to understand. ”

"And I did find a lot of things on the scene."

Kudo Shinichi sighed softly, and then slowly said what he found:

"For example, the satchel carried by the deceased clearly showed signs of being turned over."

"Her purse was taken out of her satchel and left on the floor, the documents and bank cards inside were still there, but the cash was missing."

"What do you mean..."Sonoko Suzuki understood Kudo's thoughts: "This could be a robbery?" ”

"That's right."

Kudo Shin nodded and continued to add:

"If it's a deliberate killing, it usually takes a long time to plan and prepare."

"The time and place of the crime must be carefully selected in advance."

"And I asked the staff at the tram station before I came to the site to investigate:"

"The warning sign was erected almost an hour ago because the ventilation equipment in the restroom was accidentally damaged, so it was erected to prevent the accumulation of odors from polluting the platform environment."

"In other words, this bathroom has only been unused for a short hour now."

"Before that, there were always passengers coming in and out here, and there were no conditions for being selected as the location of the crime in advance."

"So, this somewhat mitigates the possibility that the case was murdered."

"This..."The garden still felt that something was wrong:

"But, this bathroom is damaged—"

"Although it was only the ventilation equipment that was damaged, the passengers were not aware of it."

"If the deceased wasn't brought here by the murderer who had been preparing to murder her, then why would she go into a bathroom that might not be usable?"

"The reason is simple."

As he spoke, Kudo Shinichi pointed to the portable vanity boxes scattered on the ground not far from the corpse:

"See? The deceased was a fashionably dressed and well-dressed young woman, along with make-up tools that she had left behind and were knocked over to the ground. ”

"This..."

Sonoko Suzuki suddenly reacted:

"The deceased actually came in to put on makeup, just like me before?"

Makeup only requires a mirror, even if the bathroom equipment is damaged.

That's why the deceased came into this unused bathroom.

"Probably so."

Kudo Shinichi nodded and replied:

"In short, judging from the clues that can be found so far:"

"I can only speculate that the deceased attracted the attention of the murderer when he entered the bathroom alone, and the murderer followed the deceased here to commit a robbery, only to lose control of the situation and accidentally kill him."

"I see..."

"So it's just a simple robbery and murder?"

Miss Suzuki suddenly reacted:

"Wait... Didn't you see through all of this case? ”

"The murderer's methods are so simple, what are you still frowning about?"

“......”

Kudo Shinichi was silent for a while, with helplessness written on his face:

"It's useless to know how to kill..."

"There are no surveillance cameras in a large area in front of the bathroom, so I don't know who was in and out at the time of the crime."

"And this murderer probably didn't know the deceased, and he temporarily stabbed the person to death, which made it impossible for me to investigate the deceased's social relations."

"The deceased also failed to achieve effective resistance during his lifetime, and did not leave the killer's dander in his fingernails."

"Hmm..."Sonoko Suzuki pondered for a moment:

Indeed, it seems useless to know the murder method, and you have to find physical evidence that can lock the murderer.

"What about the murder weapon?"

"There should always be fingerprints left by the murderer on the murder weapon, right?"

She immediately helped Kudo Shinichi think of a direction for the investigation.

But what she can think of, the great detective can naturally think of:

"The murder weapon was indeed left at the scene of the crime."

"And it was thrown in the toilet cubicle over there."

As he spoke, Kudo Shinichi stretched out his hand and pointed to the toilet cubicle not far away.

Sonoko Suzuki took the opportunity to look:

From the corpse lying in front of the sink to the toilet cubicle, there was a distance of about 3 or 4 meters.

And on the floor between the 3 and 4 meters, a long series of small scarlet blood droplets were scattered on the ground.

"The deceased was bleeding badly from a knife in the chest and abdomen, and if she had walked, she would never have left so little blood."

"So, that long string of small drops of blood must have been left by the murderer."

"He finished killing people at the sink and quickly realized he needed to clean up the scene."

So, he walked to the toilet cubicle with the blood-stained blade, opened the door of the cubicle, and threw the knife there.

Shinichi Kudo explained in detail.

"Why did you throw a knife in that compartment?" Suzuki Sonoko was puzzled.

"Throwing a knife is just a matter of hand."

"I suspect that his real purpose should be to throw the gloves that are most likely to stain his dander into the toilet bowl of the cubicle and flush them away-"

"Yes, the murderer was wearing gloves when he robbed and killed."

is obviously narrating his discovery, but Kudo Shinichi looks very helpless:

"Because of the bloody fingerprints he left on the toilet cubicle door and on the toilet flush button..."

"Those bloody fingerprints are all smooth and flat, and there are no fingerprint lines at all."

"It's only possible to have such fingerprints if you wear latex gloves."

"This shows that the murderer is probably a repeat robber, and he has prepared latex gloves from the beginning."

"That way, he doesn't leave fingerprints anywhere either."

"And because of the latex gloves, the blood of the deceased will not get on his hands, leaving blood stains on his body."

"Finally, if this guy throws his gloves that are prone to staining his own dander into the toilet and flushes them off, it will be more difficult for the police to find physical evidence that can lock him down."

After saying this, Kudo Shinichi felt more and more depressed:

Because this case is completely different from what he has encountered before.

It is true that he has solved a lot of cases before, but somehow, those cases basically have a common pattern:

That is, the murderer likes to be clever to design all kinds of complex killing mechanisms and exquisite alibi, not only do not run away after killing people, but also stay at the scene to fight wits and courage with the detective.

And every time Kudo Shinichi appears, he can basically immediately lock out 3 suspects from the deceased's social relations (usually 3, but there are occasional exceptions).

In the end, it was the detective who used his wisdom to crack the murderous trick set by the criminal, and found out the real prisoner from the 3 suspects.

This is the process that Kudo Shinichi is used to solving crimes.

But this time...

Because the scene was sealed off in time, the potential suspects were also locked.

But there are more than 100 people in total, and they can't play the old routine of choosing 1 out of 3 at all.

And the murderer probably didn't know the deceased, so he came up and stabbed him on the spot, and disappeared directly after cleaning up the scene.

This technique is simple and crude, and there is no need for reasoning at all.

What is needed now is not a high-IQ detective at all, but a technical means that can find the traces of criminals, a pair of scientific eyes that know how to find traces.

Alas...

Kudo Shinichi couldn't help but have a strong grudge against the murderer:

This bastard...

You don't even need a trick to kill...

How can you not play according to the routine!
