"Kaoru-chan!"

In the bathroom, Kaoru Kusano was lying on the edge of the bathtub, blood slowly dripping down the bathtub to the ground, and he didn't know whether he was alive or dead.

Karasuma Ying quickly stepped forward, first reaching out and pressing on the side of Kaoru Kusano's neck, then brushing away Kaoru Kusano's loose hair to confirm the location of her wound.

"The wound is on the neck, and there is still a pulse, so I should be sent to the hospital immediately and maybe it will be saved, Mr. Kenzaki, I need to help Miss Kaoru temporarily bandage it now to stop the bleeding."

"Oh, oh! Good! Then, then I should take Kaoru out of the bathtub first......"

Osamu Kenzaki nodded, then looked around the bathroom, scrambling to find a large bath towel.

Looking at his appearance, Karasuma Ying was stunned again.

"What's going on?!"

At this moment, everyone in the living room also heard the voice and rushed over.

"Kaoru-chan!"

Makuma Atsushi, who was originally walking at the back, saw the situation in the bathroom, suddenly shouted and rushed forward, jumped directly into the bathtub and picked up the unconscious Kaoru Kusano.

"Kaoru-chan, how are you?!"

And Kenzaki Xiu on the side couldn't help but breathe a sigh of relief when he saw this scene.

"Don't move her neck!"

Speaking out to stop Makuma's somewhat radical behavior, Karasuma Ying turned his head to look at Yoko Okino and said:

"Miss Yoko, please notify the police immediately."

"Okay."

Immediately, Karasuma Ying took out her mobile phone and dialed the hospital.

“……”

"Well, I'll make sure again."

Not long after, an old acquaintance, Officer Twilight, took Wataru Takagi to the apartment.

He looked at the notebook in his hand and repeated what everyone had described before.

"So, you've all decided to take turns going to the bathroom to change into that dress you just now tonight to celebrate that Miss Kusano's engagement, and to surprise her, right?

The order of changing clothes is Miss Okino, Miss Takeno, and Miss Hoshino, and after you have changed your clothes, Mr. Mamama, the agent, goes to the bathroom to call Miss Kusano, and because there is no response, he changes to his fiancé, Mr. Kenzaki.

When you open the bathroom door, you find that Miss Kusano has passed out by the bathtub unconsciously, and this is how it happened, right? ”

"Yes." Osamu Kenzaki nodded.

"Hmmm......"

Officer Twilight nodded, then looked at Karasuma Ying with a distressed expression.

"Sister Karasuma, you have really become the same as Brother Maori......"

"Huh?" Karasuma Ying was a little puzzled.

What's the situation? Why do you say this all of a sudden?

But apparently, Officer Twilight didn't want to answer her questions.

He looked back at the crowd and asked, "So, where is Miss Kusano, who had her throat cut by the murderer, now?" ”

"I've just been taken to the hospital, and Mr. Makuma is with me, so it's not clear what ......the situation is," Yoko Okino replied.

"Then I'll check the hospital's phone number and call and ask."

Hoshino Terumi said, walking to the living room, and behind her, Yue Yexue also followed.

"I'm also with me, and my dad is also being treated for diabetes at that hospital, and I know their phone number."

"Okay."

Watching the two walk away, Officer Twilight quietly approached Karasuma Ying and asked:

"Sister Karasuma, is the murderer among them?"

Since becoming Kogoro Mori's assistant, Karasuma Ying has also solved many cases that have made the police feel tricky.

So after going back and forth, she became acquaintances with Officer Twilight.

"It's not certain yet."

Karasuma shook her head slightly, gesturing at the bloodstains on the floor that stretched from the bathroom to the door of the apartment, as well as the pile of bloodstained raincoats and gloves she had just found outside the door.

"It's also possible that the murderer is someone from the outside."

"Outside?"

Karasuma walked to the door of the apartment, crouched down, and picked up the raincoat with her gloved hands.

The raincoat was stained with blood, and it was wrapped in a pair of gloves full of holes, a handkerchief with a faint lipstick print, and a bottle of used anesthetic.

From these few things alone, Karasuma Ying roughly restored the scene of Miss Kusano's attack.

The killer wore a raincoat and gloves, and after stunting Miss Kusano with a handkerchief stained with anesthetic, he slit her throat.

But...... Where is the murder weapon?

She couldn't figure out why the murderer had only taken away the murder weapon when he had discarded the raincoat and anesthetic.

And these blood stains on the ground......

Karasuma Ying looked back at the blood dripping all the way to the floor, her brows furrowed slightly.

"These blood stains are so neat."

"What?" Officer Twilight looked at her quizzically.

"Under normal circumstances, if the murderer left the apartment wearing this raincoat, the blood stains on the ground should be more or less traced by the murderer, and it is impossible that there are no traces at all."

"What does Xiao Yingling mean?" Yoko Okino seemed to have guessed something and looked at Karasuma Ying in disbelief.

Looking directly into her gaze, Karasuma Ying's tone remained unchanged, and she said slowly:

"The preliminary speculation is that the bloodstains on the ground and the raincoat placed outside the door should have been deliberately forged by the murderer, in order to mislead us and make us mistakenly believe that the murderer is someone from outside the apartment.

Therefore, I think there are two possibilities for the murderer at present, first, the murderer is still hiding somewhere in this apartment, and the second is ......"

"Second, the murderer is among us, don't you mean that? Little sister? ”

At this moment, Terumi Hoshino, who had already finished the call, walked over from the living room, she looked at Karasuma Ying, and picked up Karasuma's unfinished words.

"Hmm." Karasuma nodded.

"That's—Isn't that a murderer......" Yoko Okino raised her hand to cover her mouth, the last thing she wanted to see happened.

"If the murderer is really among us, it can only be Miss Yoko, Miss Takeno, Miss Hoshino, and Mr. Makuma, who is not here now, one of the four of you.

Because at that time, apart from me and Mr. Kenzaki, all four of you had acted alone. ”

Karasuma Ying spoke directly about this possibility.

"So, the first thing we need to do now should be to find the missing murder weapon."

Hoshino Terumi spoke again, she looked at Officer Twilight, and said in her low, cold voice:

"A knife that has seen blood, no matter how clean it is, can detect heme, and the murderer can't hide it.

If it's found indoors, or in one of our purses, the killer is indeed among us.

But if it is not found, it means that the murderer should be someone outside, after all, I think the murderer should not deliberately hide the murder weapon and then escape. ”

"Well, ah, right...... Takagi, do as she says. ”

Looking at the calm analysis of this large pile of Hoshino Terumi, Officer Twilight and Officer Takagi were stunned for a moment, and then nodded hurriedly.

Especially Officer Twilight, the eyes of Terumi Hoshino are different.

This old girl, should she ......

"Miss Hoshino, you know a lot about this......" Officer Twilight couldn't help but say.

"It's just that I was influenced by someone when I was a child, so I have a little interest in criminal investigation......

Terumi Hoshino lit a cigarette for herself, her tone ambiguous.

"Alright, officer, you should have brought the policewoman with you, right? The search starts with me. ”
