The pages are yellowed, but it's still readable. The cover is different from the one for "Everything Becomes F," which I am also selling, but this is the second book in the S&M series. I'll discount it by 50 yen if you buy it with other items. I've read it a few times. I have two copies, so I'm selling one. Professor Saikawa and Moe Nishinosono, a student, are invited by a colleague to visit a low-temperature laboratory. But that night, in the laboratory, which was in a state of a locked room and under the eyes of many people, two graduate students were found dead. Who were the victims, and how did the culprit get inside!? The popular teacher-student duo investigates the case and gets closer to the truth... The second installment of the ultimate Mori Mystery. #Hiroshi Mori #Novel #Book #Mystery
