After dreaming of getting rich, I dressed up as a collapsed idol

He didn't continue explaining the different types of locked rooms to everyone, but instead put down his hands and began his own reasoning.

"Because this case was designed by the production team, we can completely ignore many off-site factors and only need to focus on the information the production team gives us."

"In this way, by eliminating all the impossible, what remains, however unbelievable, is the truth!"

"First of all, it's a sealed room."

Lu Qingfeng smiled broadly; he was actually quite engrossed in the game.

"This is where we fall into the first misconception: the lock on the private room can only be opened and closed by the key held by the room owner and the waiter. Leaving aside the waiter, who is an external factor, only the key in the victim's hand remains."

"Yes, the key is still on the victim, so it is a locked room."

Luo Haoming then spoke up.

"Yes, I overlooked that at first too. Let's imagine that we use the key to open the door and enter the private room ourselves. What would you do then?"

"What else can we do but walk down... Ah, I understand!"

Xia He exclaimed again as she spoke, and everyone looked at her.

"I would put the keys directly on the table instead of putting them in my pocket, because it feels cumbersome."

"This doesn't prove anything. Some people might just like to carry it on their person, or the show might have been designed poorly."

Luo Haoming has a different opinion on this.

"This……"

Xia He then looked at Lu Qingfeng.

Lu Qingfeng did not argue, but continued.

"This can also be seen as a clue provided by the production team: the murderer killed the victim and deliberately put the key in the victim's pocket."

"The murderer must also be trapped in the locked room."

Luo Haoming immediately retorted.

"Or perhaps the key we found is not the key to room number three."

Lu Qingfeng said with a smile.

Luo Haoming was taken aback, and Zhong Huaiyi and Shen Ruishu, who hadn't been involved much, also began to ponder.

"I'll try."

Xia He was a woman of action; she grabbed the key and went to room number three, followed by a cameraman.

She returned in no time; her voice preceded her arrival.

“That’s right, Lu is right, this key can’t control the lock on room number three.”

Halfway through the conversation, the man appeared before everyone, looking delighted.

"sharp."

The young writer has to admire him now.

"The logic is that the murderer puts the key on the victim, returns to the scene, and switches it with a key that only he knows where he put it during the chaos."

Zhong Huaiyi looked at the production crew opposite them.

The director and other key members of the production team smiled but remained silent.

"The murderer was the assistant. She was the first person to appear at the scene when we arrived, and she was also the last person the gentleman saw."

After the mystery of the locked room is solved, the murderer can be eliminated from among the friend, assistant, and housekeeper.

Because only the assistant and the butler were present when the private room door was opened, according to Lu Qingfeng's logic, only these two people could retrieve the key, so Xia He said.

"I think it's actually the Jazz who wanted to kill his assistant."

Lu Qingfeng said.

"what?"

The remaining people were puzzled, but someone from the production team exclaimed in surprise, as if to prove the guess was correct.

Lu Qingfeng, who hadn't been entirely sure, laughed. It seemed he had guessed correctly.

"what happened?"

Xia He was eager to know the answer, and the others were also staring at him.

Lu Qingfeng took the victim's pocket watch.

"This trick is related to Carl's 'The Three Coffins' that I just mentioned. I suspect that the production team designed this case based on this novel."

"Look at the time above."

Lu Qingfeng opened his pocket watch to show everyone; it showed a time of 10:30-something, nothing unusual.

It's been over an hour since this little theater started.

"If I'm not mistaken, Mr. Frank's pocket watch and this one are only one time difference apart."

The crowd took the pocket watch from the actor's hand, opened it, and compared it with the watch.

"Really, it was about twelve minutes late."

“Think again about what the three of them said about the time they were supposed to meet with the jazz.”

"My friend arranged to meet me at nine o'clock, the assistant at nine-tenths, and the butler at nine-twenty. After the assistant met the gentleman for the first time, she arranged to meet him again in ten minutes, along with the butler, but by then the gentleman had already died."

Old Shen looked at the clues they had written down on the table.

"But in reality, because the friend's watch was twelve minutes slow, their meeting actually took place after the assistant's."

Luo Haoming continued.

"So the correct timeline is that he met with his assistant at 9:10, then went to the restaurant to meet his friend, and finally the butler came to private room number three to meet the gentleman. This creates a time difference."

"This time difference allows the jazz to kill the assistant, find the body when the butler goes to room number three, and still have an alibi."

Everyone suddenly realized.

"But the assistant discovered the trick and poisoned the knight."

Xia He followed Lu Qingfeng's line of reasoning.

Lu Qingfeng shook his head again.

"You forgot that the jazz drank the poisoned glass himself, not by force."

"And the assistant said that after meeting the gentleman for the first time, she was taken to a restaurant where she bumped into a waiter. She went back to her private room to change her clothes before meeting the gentleman for the second time."

"I'm about to faint, just tell me the answer."

Xia He shook her head, indicating that she couldn't do it anymore.

Lu Qingfeng smiled.

"The murderer should be the butler. He probably knew that the Duke was going to kill his assistant, and then he turned the tables and killed the Duke."

"There were two wine glasses in the private room. The gentleman should have poured himself a non-poisoned glass beforehand and then poisoned the bottle. The butler came to the private room in advance to meet the gentleman, and then used a trick to make the gentleman leave the private room briefly, so that he could pour the poisoned wine into the non-poisoned glass."

"Then, when the Jazz returned, he was verbally provoked, causing him to have an anxiety attack and drink the poisoned wine. In other words, the Jazz was already dead before he met his assistant for the first time."

"I understand."

Luo Haoming clapped his hands.

"So the man the assistant met the first time was actually the butler in disguise. The reason the assistant was asked to meet him again in ten minutes was to frame the assistant and clear her own name."

Lu Qingfeng gave a thumbs up.

"If that's the case, the butler still has the key to room number three."

Xia He's eyes lit up as well.

There's no need to investigate anymore, because the production crew has already started clapping, proving their reasoning is correct.
