At 2.40 a.m., there were several people standing in the corridor on the fourth floor of a large hospital in a certain city.

"Miss Nurse, it's the man with a bandage on his head, right?" A man in a police uniform asked a young nurse dressed in white in front of him.

"Yes, comrade policeman, that's him." Miss Nurse replied.

"Who sent him?" Another comrade policeman, who was standing next to him, asked.

"A taxi driver, said that he saw this person come out of the tunnel, as if he had lost his soul, as soon as he got out of the tunnel, he fell directly on his knees on the ground and fell asleep, and the taxi driver also left a phone number, and the number was at the nurse's station."

"Oh, then, you go and get the phone number with Miss Nurse, call and ask, and I'll go in and ask this person later." The policeman who was the leader said to another policeman next to him, after finishing speaking, the policeman next to him left with Miss Nurse, and after a while, Miss Nurse came back, and the policeman who spoke nodded at Miss Nurse, signaling that he was going in, Miss Nurse opened the door, went in and said a few words to the injured man and came out, after Miss Nurse came out, Comrade Police went in.

The police comrade looked at the man in front of him who was wearing a bandage and leaning on the hospital bed, his eyes were blank, and the whole person looked terrible, this man claimed that he had a car accident and killed someone, but he didn't know how he came to the hospital, the first thing he said when he woke up in the hospital was to call the police, to turn himself in, he killed someone, the nurse calmed the patient and dialed the phone and contacted the police, the police sent three people to the scene of the crime, two people came to the hospital, and now the man standing in front of the man is the captain of the team, Captain Huang, Captain Huang sat down on the edge of the hospital bed, looked at the man and said, "You want to turn yourself in?" ”

The man looked down listlessly and said, "Well, I hit and killed someone." Captain Huang said, "How do you know?" You don't even know how you got here, are you sure someone died? At the same time, he pointed to the other party's head, meaning what's going on with your head? The man raised his hand and touched the place pointed by Captain Huang and said, "This is the injury I suffered after hitting the steering wheel after the car accident... I hit and killed someone... I killed someone... I... I... I'm sorry... I'm sorry..."The man cried as he spoke, and Captain Huang took a deep breath and continued to ask, "I'll say it again, how do you know?" ”

The man looked listlessly at the railing on the hospital bed and said: "I came back from a business trip, there were few people at night, so I drove the speed to the fastest, although I didn't speed, but the speed was still very fast, when I drove into the tunnel, although the lights were very bright, but I still couldn't see the innermost road, I didn't slow down, because I often walk this road, so I was very confident, I felt that when I was about to drive out of the tunnel, the sound of the radio on the car became vague, and the sound of clacking made me very annoying, so I adjusted it twice with my hand, This tone is even more noisy, I angrily beat it with my fist, and adjusted it again, the sound of sizzling is gone, but the sound of the siren came out, very harsh, I just wanted to change it with my hand, suddenly I saw a person in reflective clothing in front of me, I subconsciously hit the steering wheel to avoid him, but he pounced in the same direction, he may have the same idea as me, but also want to avoid the other party, I hit the wall in the tunnel, I also hit the steering wheel, I feel very dizzy, my nose is very sore and painful, I shook my head, and then felt an uncomfortable feeling, coughed a few times, because the cough was too hard, I felt the back of my head hurt, I couldn't help but cover the back of my head with my hands, and got out of the car in a daze, I wanted to see how the car was, and found that there was a person pressing on the front of the car, his helmet was still on, and his eyes were staring at the side, I wanted to save him, but I didn't know what to do, and I didn't know what to do, but I seemed to have walked a little way, as if out of the mouth of the tunnel, Then a sense of relief hit, and then I woke up again and was already here. ”

Captain Huang just wanted to say something, but the mobile phone rang, Captain Huang looked at the caller ID, it was his colleagues who went to the scene of the crime called, he got up and walked outside the ward, and picked up the phone: "Hey, how is it?" Did the dead or wounded be found at the scene? He hesitated and said, "What dead and wounded?" At the scene, a car hit the wall, everything else was fine, no one was found, and there was no blood stains or anything like that, how to look at it was also a simple car accident caused by fatigue driving, the brothers in the bureau checked the surveillance, the driver of the car drove in from him to he walked out by himself, there was no one else but him during this period of time, and he suddenly turned and crashed into the wall. Captain Huang pouted and replied, "Okay, I see." ”

Captain Huang found the nurse and asked the nurse if she had done a test for the man, such as a blood test and urine test. After the nurse answered no, Captain Huang went to the colleague who called the taxi driver, and the colleague told him that the phone could not be reached, maybe he was asleep, and he would contact him tomorrow? Captain Huang hummed, went back and found the nurse to ask her to check the patient, suspecting that this person had other problems, although he didn't say it, but Captain Huang suspected that the man was hallucinating while driving on drugs and caused the crash to enter the hospital.

The next morning, Captain Huang took a nap in the bureau and washed his face with cold water, and then walked to the office, where the taxi driver had come to cooperate with the investigation, Captain Huang sat down and looked at him and said, "You are the kind person yesterday, I thank you for him." The taxi driver looked to be in his 50s, with an honest face, and after hearing the policeman's words, he hurriedly waved his hand and said: "What is there to thank for this, anyone who encounters this kind of thing will go to help, but I don't know what you asked me to do when I am comrade police?" ”

Captain Huang took out a cigarette and gave it to the other party, the other party waved his hand and didn't want to, Captain Huang let it go again and let it don't matter, the taxi master took it very politely with both hands, Captain Huang lit it, and he also lit it, took a puff and said: "That's the case, the person you saved yesterday, he woke up and said that he wanted to call the police, he wanted to turn himself in, saying that he had killed someone, but the surveillance screen and our police investigation at the scene of the crime did not find any clues, let alone people, not even a mouse, no bloodstains, no personnel at the scene, Neither our investigation at the scene, nor the surveillance footage, there is none, but this person has always been very firm that he hit someone, hit a man wearing a reflective suit and a hard hat, so we want to ask if you found anyone else at the scene. ”

The taxi driver frowned and said with a little excitement: "No, there can't be anyone!" At that time, he was himself, he hit the wall of the tunnel, I thought he was tired of driving and accidentally fell asleep, before I carried him into my car, I also checked his car, inside and outside the car, to see if there was anyone else, to see if there were any valuables, all put on him, just himself, in no one else, if he hit someone will definitely be able to find, the scene is himself and his car, I just sent a passenger back to the road, walking on another road, I saw that there seemed to be a person coming out of the tunnel, a little lost soul, I went over to take a look, just drove over and got out of the car, wanted to ask him if he was okay, he knelt directly on the ground and fainted, this time I frightened me, I quickly stepped forward and called him a few times, shook him a few times, and saw that he didn't respond, so I sent him to the hospital. ”

Captain Huang snorted and said, "Then did you smell the smell of alcohol or the strange smell of smoke when you gave him away?" The taxi master knew what Captain Huang was referring to and said, "No, but I think of a thing, I don't know if it has anything to do with it, and I'm afraid that the police comrades will laugh at our superstition of opening a taxi." ”

Captain Huang took a hard puff of his cigarette, and after extinguishing it, he looked at the rental master and said, "It's okay, you can say it." ”

The taxi driver said as if he was recalling something: "I heard that there was an accident when the tunnel was still under construction more than 20 years ago, what is the car that made the tunnel?" It's big, big, semicircular, what's the scientific name? ”

"Lining trolley," Captain Huang interjected.

"Yes, yes, yes, it's just, there's no culture, I can't say it, isn't that car like a house, with a lot of steel shelves, steel pillars, railings and whatnot? During the day, the workers are busy and go back to the dormitory to rest, there are two engineers wearing reflective clothing and wearing hard hats are still busy, studying some related matters inside, at this time there is a car drunk driving at night, a group of young people, drunk do not know what their surname is, obviously saw that it was written that the construction ahead is forbidden to pass, but also went inside, thinking that there was no one inside, as a result, two engineers were busy inside, one of them pushed him away in order to save the other, he was hit by the car on the iron pillar, died on the spot, and then the people in the car were sentenced, After this place was built, I often heard that there were people here, and those of us who drove taxis would rather believe it than believe it, comrade police, you should have heard of it, right? ”

Captain Huang shook his head, saying that he hadn't been transferred at that time, he wasn't here, and the other colleagues were too young, some had not been born at that time, and some had not yet gone to kindergarten, so they didn't know about it at all.

Captain Huang asked the rental master to go back first, went to the hospital by himself, and asked the nurse about the test results, and the test results showed that everything was normal, no drugs, stimulants and other ingredients were detected in the blood and urine, and the patient had no mental problems, Captain Huang sat on the bench in the corridor with a frown, and fell into deep thought with his head down...
