"I didn't expect Yu Haobu's time of death, those suspects were on the second floor." Zheng Hanfei pinched his chin, his expression a little disappointed, "In other words, they still have time to commit crimes, and it seems that no one can be ruled out." ”

"That's right." Meng Wu seemed to remember something and asked Ling Hua, "What about Captain Mo Gang?" Didn't you say that Captain Mo Gang went out with Zhong Xian at 11:00, so was Captain Mo Gang on the second floor before 11:00? If so, what is he doing there? Could he have seen something? ”

"I don't know. When Mo just comes back, you can ask him. "Oh, yes, yes, at 11:00, I remembered a strange thing. ”

"Strange thing?!" Zheng Hanfei and Meng Wu said in unison.

"yes." Ling Hua nodded and recalled: "I remember that Mo Gang and Zhong Xian had just left, and I vaguely heard a bell from the second floor, just like the sound of a pendulum clock, but I remember that I didn't hear any pendulum clock sound before this, if I hadn't entered Yu Haobu's room this time, I would have thought that there was no such thing as a pendulum clock in this house." ”

"The bell of the pendulum?!"

Zheng Hanfei and Meng Wu lowered their heads at the same time, and began to think in their minds, and after a long time, Meng Wu slowly raised his head, glanced at Zheng Hanfei, who was still pondering, and said slowly: "Zheng Hanfei, do you remember what Yu Haobu said?" ”

"Of course I do!" Zheng Hanfei raised his head and said, "As soon as this pendulum clock reaches the hour, the small ball in the clock will bounce up and hit the top of the pendulum clock, thus making a huge sound to tell the time, which is similar to the time of the pendulum clock, but now the time telling function of this pendulum clock has been broken, and Yu Haobu has not heard this sound in recent years." ”

"If this is true, then it is too strange, right?" Meng Wu continued, "In the whole house, only Yu Haobu's room has a pendulum clock, but this pendulum clock is already broken, it can't tell the time, and it can't make a sound, but in that case, what is the sound that Ling Hua listened to at 11:00? I don't believe that the police have auditory hallucinations. ”

"That's inevitable." Zheng Hanfei replied, and then he sighed lightly, squatted in front of the pendulum clock that fell to the ground, and swept a piece of broken glass that was a bit of an eyesore, which could be said to be blocking the view, and then Zheng Hanfei found a long thin rope, tied into a small circle at both ends, which made Zheng Hanfei's eyes burst out with a trace of light, obviously this uncomfortable thing appeared at the scene of the crime and directly attracted Zheng Hanfei's attention, it can be said that Zheng Hanfei has found some clues, some breakthroughs.

"What is this...... Meng Wu stepped forward to take a look, was slightly stunned, and said in surprise, "How can such a thing appear here?" Do you say ......"

"It's a breakthrough!" Zheng Hanfei stood up and said excitedly, "The long string with two circles, plus the door lock in Yu Haobu's room is a kind of door lock that switches up and down, as long as you force down, you can lock the door, plus the pendulum clock placed in front of the door, the small ball in the pendulum clock, if I guessed correctly, this is a mechanism, and it is because of this mechanism that a secret room can be formed." ”

"That's not right!" Hearing this, Meng Wu knew what Zheng Hanfei wanted to express, and after thinking about it carefully, he spoke out to deny this reasoning, "Let's not say that this pendulum clock is broken, even if it is repaired, this pendulum clock can only move upwards, not downwards at all, so that you can't exert downward force on the door lock at all, and the door can't be locked at all!" ”

"Not necessarily." Zheng Hanfei shook his finger and explained, "Whoever said that the ball moved upwards, maybe it moved downwards, besides, any of us saw that the ball of the pendulum clock was moving upwards, as the so-called seeing is believing and hearing is false, unless there is some video for us to see." ”

"I can provide that." The sudden voice startled everyone, and when they heard the voice, they found that Zhong Xian and Mo Gang had come back at some point, and their faces were obviously a little bad, especially Zhong Xian, whose body trembled again, it seemed that Yu Haobu's death made him think about the mermaid again.

"Village Chief Zhongxian, you said you could provide it? Did you ever record it? Zheng Hanfei and Meng Wu were a little surprised, but they were also a little happy, at least they could determine whether their reasoning was correct or not through the video, and they could also find new clues through the video.

"Yes." Zhong Xian replied truthfully, "When I bought this pendulum clock, I thought it was very fun, so I took the VCR at home and took a picture of it, which has not been deleted, and is stored in the VCR, if you need it, I can give it to you." ”

"Thank you." Zheng Hanfei saw a trace of disdain in Zhong Xian's eyes, and understood that Zhong Xian still distrusted himself and Mengwu, and believed that Zhong Xian's purpose in doing this was purely to let Mo Gang and Ling Hua come to see it, so as to solve the case as soon as possible, and told them that it was just a favor to Mo Gang, but out of moral character, he still had to say thank you, after all, seeing and listening to Mo Gang and Ling Hua's reports with his own eyes were two different things.

"In my room, come with me." Zhong Xian took Zheng Hanfei, Meng Wu, Mo Gang and Ling Hua to his room with crutches, then took out a video camera from a wooden cabinet, handed it to Zheng Hanfei, and said, "That's it, you guys take your time." ”

Zheng Hanfei is very skilled in operating the camera, and then the video he wants appeared on it, and suddenly four heads and eight eyes stared at the screen, only to see the pendulum clock in the video as Yu Haobu said, on the hour, the small ball in the pendulum clock quickly bounced upward, hitting the upper release of the pendulum clock, making a sound, and the sound was no different from the sound of the pendulum clock.

"That's right, that's what I heard!" Ling Hua said, "There is no difference, it seems that it did come from that pendulum clock." ”

"That's impossible." Zhong Xian said, "That pendulum clock was not good for a few years ago, and it didn't get any better when I repaired it, so I only use it as an ordinary clock that can read the time now. ”

"Can the ball in this pendulum clock change the direction of its movement?" Zheng Hanfei put forward the question he wanted to ask the most, "As I just said, change the direction of the ball from bottom to top to top to bottom?" ”

"Impossible, absolutely impossible!" Zhong Xian denied Zheng Hanfei's conjecture, "The sound of the ball hitting the pendulum clock from the bottom to the top is designed by the manufacturer, and it cannot be changed at all. ”

Could it be that your conjecture is really wrong? Zheng Hanfei pinched his chin, his eyes gradually narrowed a slit, and the clues he got now all pointed to his conjecture being wrong, but he had always been a little disbelievable in his heart, and always felt that these clues could lead everyone in the wrong direction, but he didn't have any ideas now, but one thing he was sure of was that there was nothing wrong with the video of the pendulum clock, that is to say, it was a real video that had not been processed in any way, and Zhong Xian did not take out a fake video to prove it, Otherwise, Zheng Hanfei believed that the four of them would include Zhong Xian in the ranks of important suspects as soon as possible.

……

"What are you thinking?" After walking out of Zhong Xian's room, Meng Wu saw that Zheng Hanfei was still thinking about something, and couldn't help but be a little curious, and asked, "Do you still think that the pendulum clock was used as a mechanism to make Yu Haobu's room a secret room?" You still haven't given up, it's hard to understand, haven't you listened to Zhong Xian's words, haven't you watched the video just now? ”

"I always feel a little suspicious." Zheng Hanfei said slowly, "I can't tell what's wrong, oops, it's really annoying!" The murderer has not been found, the mystery of the secret room has not been solved, and if it continues, there is a high probability that a third or fourth corpse will appear! ”

"It's useless to bother." Mo Gang patted Zheng Hanfei on the shoulder and encouraged, "Troubles can't solve any problems, you should calm down and analyze it well, you will only let the murderer hide in the dark and laugh, so that he can continue to increase the number of crimes." ”

"That's right, detective, the truth is in your heart, it's just that you've been blinded by the eyes that are good at deception, and if you continue like this, it will disappoint me too much!"

"Who!" Hearing the familiar and unfamiliar voice, Zheng Han raised his head violently, ran to the stairs leading to the first floor, and did not find anyone at all, his face was a little solemn, if he guessed correctly, the voice just now, it must be that he wanted to arrest the afterimage, but he didn't understand why the afterimage appeared at this time, and, from the tone just now, it seemed that he knew their situation very well.

Say?! Zheng Hanfei's pupils shrank slightly, and he looked at the room on the second floor, thinking, the afterimage, should it be among them?
