I strode towards the elevator, completely ignoring the surprised eyes behind me. When I desperately pressed the elevator down button, Tang Zhenguo and the others also followed, and Captain Gu asked puzzledly, "Did you find anything?" ”

I heard Lao Lu behind me say, "Follow him, and you'll understand later." ”

I turned around and said, "Big discovery, big discovery, definitely big discovery." The three of them looked at me, still surprised.

Coming to the first floor, I walked briskly, almost all the way around the back of the building, and several of them followed.

At the back of the building, there are still blue floor-to-ceiling windows, but unlike the front, these windows extend from the ground floor to the top floor.

I carefully examined every glass window on the ground floor, and finally I found a clue. On one of the glass windows, there were several faint, staggered circular marks, all twenty-five centimeters in diameter, apparently the marks left by the same thing. And underneath the circular imprint, there are not very obvious friction marks left on the glass.

Among them, the friction marks on the glass window, close to the ground, are dusty, and when you go up, the dust becomes less, leaving a residual mark, like a blurred mark left by rubber pressing on the mirror.

Tang Zhenguo saw these traces and exclaimed, "What's going on? Do the cornices walk on the wall? ”

Martial arts fan Lao Lu said seriously: "Could it be the long-lost gecko wall-swimming skill?" ”

Captain Gu on the side frowned and looked at these traces, falling into deep thought.

I took a few steps back, adjusted the perspective left and right, looked at the glass at a higher place, and there was also a faint imprint, I had a conclusion in my heart, walked to Lao Lu's side and said: "It is indeed a gecko swimming wall, but it is not the kung fu in martial arts novels, but with the help of modern suction cups, climb up." The strange sound that the manager heard was the sound of hitting the glass during the climb. You see, the first circular mark is where the right hand suction cup sucks the glass, and this circular mark is 220 centimeters above the ground. The height of 220 centimeters is by no means the height of the climber, and the reasonable explanation is that the climber lifted the suction cup above his head and then sucked in the glass above. ”

Tang Zhenguo suddenly said: "I understand, this person is climbing up with a suction cup in one hand, and his arm strength must be amazing." ”

I smiled and said, "It's true that I climb with a suction cup, but I can't say that with amazing arm strength, because this climber's method is definitely not to use brute force." ”

Lao Lu said suspiciously: "How can you climb without brute force?" There is no point of focus on the feet. ”

I said, "The feet have a point." Although there are no fulcrums or grooves in the glass wall, climbers can suspend a pedal under the suction cup. With pedals and suction cups, the way to climb is simple. From these circular marks, it can be seen that climbers are accustomed to using the right-handed suction cup first. When the right hand suction cup is firmly sucked in the glass above the head, the right foot can step on the pedal to climb up a certain height, and then make the weight of the whole person fall on the pedal suspended under the suction cup, and stand on one foot with the right foot. At this point, lift the suction cup of your left hand above your head to suck the glass, and step on the pedal with your left foot to climb some more distance. In this way, you can climb to the roof by alternating them one after another. Those abrasions were obviously caused by the edge of the shoe rubbing against the glass when standing on one foot. ”

Lao Lu nodded and said: "The climbing method you said is indeed effective, but why did this climber climb the Mu Jue Building?" ”

"It is estimated that it has a lot to do with Mu Wei's fall, let's go to the roof garden immediately to have a look." After I finished speaking, I rushed to the elevator of the building in a hurry.

When I come to the roof garden, I can better enjoy the beautiful scenery of this garden during the day, but all my energy at this time is focused on the fun of solving crimes, even if there are ginseng fruit trees in the roof garden, I will definitely not take a second look.

Sure enough, on the other side of the roof garden, there was also an open-air lounge, and the climber climbed all the way from downstairs to this lounge.

I walked to the glass railing at the edge and did find traces of climbing, but I didn't find any useful clues such as fingerprints and footprints.

The so-called mountains and rivers are doubtful, and there is no way out, and the willows and flowers are bright and another village. To my surprise, I found some soot in the corner of the edge of the glass railing, which was the ash of the Montecristo Master Cigar. Apparently, the ash was from the same cigar cap in the open-air lounge opposite.

So I made a bold assumption that before Mu Wei fell from the building, he had met with this climber, and maybe it was this climber who killed Mu Wei.

But this idea was immediately shattered, and another idea became clear. I almost screamed with joy, and everyone looked at me in amazement.

I cleared my throat and said to everyone: "I can be sure that Mu Wei committed suicide, but this suicide is likely to be forced to be helpless, and there is a great secret behind it." ”

Lao Lu hurriedly said, "Analyze it." The rest of the people looked at me expectantly.

I said, "Let's start with last night's blackout, which must have been created by the climber's accomplices." And before Mu Wei asked Secretary Jiang to leave, it showed that Mu Wei knew that the climber was coming. Let's talk about the cocktail glass that was wiped clean, in fact, that night, Mu Wei didn't drink blood wine at all, it should be said that the power went out when he just took out the wine glass. In his hurry, he took the glass in his hand and closed the freezer. At this time, the climber appeared in front of Mu Wei. For some unknown reason, the climber snatched the empty cocktail glass from Mu Wei's hand, and after a while of talking, the climber wiped his fingerprints off the glass with something like a glove or handkerchief and placed it on the outside of his desk. Then the two went to the roof garden, where the climber sat in front of the chair, casually lighting a cigar, while Mu Wei stood by the glass fence in a nervous mood. The two didn't know what they were talking about, and finally Mu Wei jumped off the building and died. ”

Lao Lu held his chin with his hand at this time, and asked puzzledly: "You said that the climber made him commit suicide by jumping off the building through the dialogue with Mu Wei, so what did this climber say, so lethal?" ”

I said, "I guess in the office, it should be about Mu Wei's illness and something related to blood wine, otherwise the climber would not have taken the wine glass from Mu Wei's hand." And coming to the open-air lounge on the roof, it shows that in the office, the climber has shaken Mu Wei's heart and made Mu Wei have suicidal thoughts. But after Mu Wei came up, he began to hesitate and entangle, standing in front of the glass fence for a long time, so there were so many Mu Wei's fingerprints left on the glass fence. However, it is unknown what reason the climber used to make Mu Wei commit suicide. It could be a threat, it could be a promise, it could even be a hypnosis, who knows? ”

Tang Zhenguo asked, "How did the climber leave after Mu Wei committed suicide?" Is it climbing down again? ”

I smiled and shook my head and said, "No, because the traces of the climb are only upward, not downward." I guess he jumped. ”

"What? Jump? "They all said it was incredible.

I said, "Yes, I jumped off, but I should have carried a parachute." ”

These people all poked their heads out and looked at the outside of the building, Tang Zhenguo said: "Although it looks quite high, if you want to say that it is used for parachuting, is it still a little low." ”

I smiled and said, "That's enough for extreme low-altitude skydiving." Extreme low-altitude skydiving requires a height of about 100 meters from the parachute fully open to the adjustment of the parachute, and it takes about 100 meters to land safely. The Moujue Building has 39 floors, which is an office building, and the height of the floor is generally between 3.8 and 4.2 meters, so the height is more than enough for extreme low-altitude skydiving. ”

Lao Lu was still skeptical, so he said: "No matter how I listen to these inferences of yours, it feels a bit fantastical, what do you use to confirm it?" ”

"Okay, come down with me." I ran to the elevator again.

After going downstairs, I ran straight to the back of the building, about fifteen meters away from the building, and in this weedy field, I found traces of trampling and rolling, and there were traces of a large area of turf that had been dragged, which were typical of the traces left by a parachutist after landing.

I pointed to these traces and said to Lao Lu: "Look, this is the evidence. This large trail of drag is the trace left when the umbrella is closed. This part of the Economic Development Zone has not been fully developed, and there are few street lights at night, plus the power outage of the Mujue Building. So at night, this area is almost a dark blind spot, giving the perpetrators a good condition for escape and concealment. ”

Lao Lu squinted his eyes and tilted his head and asked, "Eh! I said Ouyang, how did your head grow melon seeds, how could you come to such an incredible conclusion so quickly. ”

I said, "Actually, these conclusions are traceable. The first is the cigar ash found, and the ash from the roof indicates that the climber has stopped at the edge of the building. And he smokes a Montecristo Master Cigar, which is a favorite among sports enthusiasts. In addition, the climber climbed the Moujue Building with a suction cup, which shows that this person is a person with strong motor cells and has a lot of experience in extreme sports. So it's not hard to speculate, what extreme sports can leave the building quickly and without leaving too many traces? Obviously, it is not possible to rappel through the rope, what will happen to the rope after the person comes down? Therefore, extreme low-altitude skydiving is the best choice. ”

Lao Lu wiped a handful of his hair: "What kind of person?" is such a, saying a few words to say that the boss of the Mujue Group committed suicide by jumping off a building, and he is proficient in so many extreme sports, this person is not simple. ”

I said, "It must be someone Mu Wei knows, and he is a rich man, or a healthy person." Based on the footprints on the ground, it is inferred that this man is a man between 175 cm and 170 cm tall. ”

When Lao Lu heard this, he patted me on the shoulder and said, "When you say that, it seems that the scope has narrowed a lot." Then I'll ...... right away."

"Boom !!" A deafening loud bang interrupted Lao Lu's words, and at the same time frightened all four of us into a slump and almost threw ourselves to the ground.

When I reacted, I saw smoke billowing and flames rising to the sky on the road in front of the Mujue Building.

What happened?
