"I know who the murderer is," Kana called everyone together, "The murderer took advantage of the time gap to create a bloody case. I'm right, after sending the information sheet, there is a perfect alibi - Miss Keiko Kiyosawa. ”

"What stupid are you talking about, I obviously don't have time to kill."

Kana began her reasoning: "This must be an event you have planned for a long time. First of all, you agreed with the deceased, Miss Takamine Tomomi, about a time to come to the school building to meet - it was just after you went downstairs after you delivered the information sheet. Here's the thing, after you send the information sheet, you come to the first floor of the teaching building at the appointed time to meet with Jimi, and then there is an argument, which is why Miss Dai Mei will hear the quarrel. In the rush of the argument, you strangled Zhimi, of course, you were wearing gloves at that time, and the time should not have been 12:40. After killing Tomomi, you"

"Wait!" Keiko interrupted Kana's words, "You obviously heard Tomomi Takamine's screams at 13:02! ”

"That's what I'm trying to explain. The reason why everyone hears Jimi's screams is because after you killed her, you installed a small voice recorder somewhere on the first floor of the school building. What was recorded in it must have been the screams made by Jimi before. You turn up the volume to the maximum, set a time of 13:02, and leave. ”

"What! This is just your guess, and there is no evidence at all. And Aiko Sato, who has been hiding in the school building, is more likely to commit a crime! ”

"Of course, there is evidence, and that is the blood stain on the heel of the deceased - you said that your hand was cut by glass before, so this blood stain must have been left by the blood stain left when you pinched Jimi! Just verify the bloodstains and everything is ok. And, since it's a small voice recorder you have installed, then, just look for it, and you will find a small voice recorder with your fingerprint! ”

Finally, Keiko confesses to the fact that she killed Tomomi. The reason is actually because of some mutual incomprehension between friends

Solved a bloody case, and Kana is also famous in school. But she still looked indifferent

Outside the campus, a strange voice came: It's really funny
