Ni Zhe pulled the window fence of Yuan Dapeng's dormitory unconvinced, but it didn't move at all, and only one hand was allowed to pass through the fence. Then Ni Zhe checked Room 105, which was an empty room with no one staying. The door was locked tightly with a latch, and there was no sign of prying. The window frame inside was also closed with a solid fence. Ni Zhe shook his head in disappointment. When he returned to the bureau in the afternoon, Xiao Hu reported a new clue to him: some fine brown paste was found on the cut surface of the two broken ropes, and the specific composition is still under further analysis. Ni Zhe began to recall the whole case, and all his thoughts flew around in his mind, and finally arranged into a complete straight line. Dear readers, all the clues of this case have been presented to you. I can say responsibly that the murderer is Yuan Dapeng. Then please tell me his modus operandi and what evidence is there? In the dark interrogation room, Captain Ni and Xiao Hu sat at a black wooden table. They stared at Yuan Dapeng across the table with serious faces. Yuan Dapeng bowed his head and remained silent. The exhaust fan on the wall creaked, as if waiting for the moment to break the silence. "You killed Zhu Kai, didn't you?" Ni Zhe finally broke the silence. Xiao Hu also began to take notes. "No." The other party said firmly, "I didn't kill him. Besides, how could I kill him?" Ni Zhe smiled faintly and said, "I have seen through your tricks. Do you think that arranging the scene as a so-called secret room can make Zhu Kai look like he committed suicide?" Yuan Dapeng trembled slightly and did not speak. Ni Zhe continued, "You locked the door from the outside with Zhu Kai's key, and then put the key back into the pocket of the corpse's pajama pants."
"This is impossible! Stop talking nonsense," Yuan Dapeng interjected.
"At first, I thought it was a cliché trick, using fishing line to pull the key from the gap under the door into the pocket of the sleeping pants. But after carefully examining the inside and outside of the pocket, I found no signs of fraying or punctures from sharp objects. So I ruled out that possibility."
"So he committed suicide," the other party exclaimed angrily.
"Hold on a second. While you can't return the key alone from outside to inside, you can bring it in along with the body," Ni Zhe said meaningfully.
"What do you mean by that?" Yuan Dapeng paused, confused.
"Let me explain your entire process of committing the crime," Ni Zhe said, his eyes fixed intently on Yuan Dapeng, while Xiao Hu sat up straight, all ears.
"You first killed Zhu Kai, making him hold a pair of scissors. You hung a piece of rope on the fan bracket to make it look like Zhu Kai had cut the rope to call for help. Then comes the climax of your scheme..." Ni Zhe picked up a teacup from the table and took a sip of hot tea.
Setting down the cup, he continued: "You prepared a long enough hemp rope, tying one end to the window frame outside Room 305 and fashioning a noose to tightly secure it around the neck of the corpse. Then you threw the body out of the window of Room 305, leaving it hanging outside. After that, you exited the dormitory and forcefully pulled down on the rope to close and lock the door with the key. At this point, the rope was wedged in the gap under the door, which is about 1.5 centimeters wide—enough to accommodate an ordinary hemp rope.
Once everything was ready, you returned to your own dormitory, Room 205—the one directly below. At this moment, the body was hanging just outside your window. Although the window bars wouldn't allow a person to pass through, they were more than sufficient for a hand to reach through. You extended your hand with the key out of your window and stuffed it into Zhu Kai's pocket.
Next came the final step: you went back outside Room 305 and forcefully pulled on the extended hemp rope in the hallway. The body was pulled back into the room and dragged along the floor to behind the door. Finally, all you had to do was cut the rope wedged under the door with scissors and retrieve all of it.
Thus, both the key and body returned inside. Moreover, the severed rope at his neck, the broken rope tied to the fan bracket, and the scissors in his hand would lead people to believe he had cut himself free and crawled to the door for help. In reality, these two pieces of rope were not cut by the same blade. Your brilliance lies in disguising your locked-room trick as 'a self-rescuing corpse.'
"The snow on the windowsill outside Room 305 is missing a patch where it was scraped off when pulling in the body; abrasions on the back of its head and arms, along with stains on its clothing, were caused by dragging it across the floor; and there are grease marks in the door gap that you applied to reduce friction when pulling on the rope for ease. Furthermore, only someone living directly below could have executed this trick. Now do you have anything else to say?"
After listening to Captain Ni's reasoning, Xiao Hu was left dumbfounded.
Meanwhile, Yuan Dapeng clenched his fists, displaying a defiant attitude.
"I want evidence!" he shouted.
"Do you remember what you were doing the day we came to your dorm?" Ni Zhe suddenly asked. "You were using scissors to cut open a packet of meat sauce for instant noodles. We found some paste-like substance at the cut on the rope behind the corpse's neck. After examination, it was determined to be consistent with the remaining contents of one of the meat sauce packets in your dorm's trash can. You really shouldn't use scissors that have cut meat sauce to cut other things, and it's not a good habit to not wipe the blades after using them."
The other party was speechless. Ni Zhe continued, "And one more thing. That day, when I deliberately said that Zhu Kai committed suicide and cut the rope, you remarked, 'I knew he wouldn't dare to commit suicide; he would still end up cutting the rope.' I only mentioned the verb 'cut,' so why did your mind immediately respond with 'scissors'?"
In the end, the criminal confessed his motive for murder, which boiled down to two words: jealousy.
Yuan Dapeng had originally been the physics class representative with top grades. However, after being placed in the same physics class as Zhu Kai during their senior year, Zhu Kai's performance far surpassed his own.
Under pressure, Yuan Dapeng's grades began to plummet, and he flunked the recent mock exam. Petty and resentful, he blamed all of this on Zhu Kai, which led him to harbor murderous intentions.
With snow suddenly falling over the past few days and the geographical advantages providing cover, Yuan Dapeng devised this locked-room murder scheme.
Finally, the snow began to melt.
