After Bruce and Lex arrived in Metropolis, they had to rely on the Luthor family to open the way, but Lionel didn't leave nothing but the family business.

Money and power are not separated, the police chief of the Metropolitan has a fairly good relationship with the Luthor family, and when he heard that Lex was interested in the murder, he gave all the dossier materials to Lex.

However, the police officers did not find any special clues, so Lex proposed to the police chief that he wanted to go to the scene, but the police chief of the metropolitan was very embarrassed, and he said on the phone:

"I'm sorry, Mr. Luther, but we're going to have to make a site visit for your safety, I'm afraid it's ......"

"I guess the police department is still short of a new batch of protective equipment, right? With such a brutal murder, the quality of the police officers' armament also needs to be improved, and the Luthor family has always been concerned about the safety of the metropolis......"

Lex didn't finish his words, but who wouldn't understand this kind of thing?

To Lex's surprise, the police chief still didn't agree, and after he hung up, Bruce stood behind him and said, "There's a problem, with money to open the way, there's no way he won't even let you see the corpse." ”

"It's okay, we can go straight to the morgue, there's nothing here that the Luthor can't do." Lex replied.

The bodies of both murders were stored in the morgue of a hospital close to the police station, and the forensic doctor had not yet had time to perform the autopsy, so if they had gone now, they should have seen the complete bodies, which happened to be sponsored by the Luthor family.

However, when the two came to the morgue, they found that there was no murder body here, and after calling up the morgue's surveillance, the surveillance showed that there was not even a video of the corpse.

In other words, after investigating the crime scene, the police did not store the body in the morgue at all, which is very abnormal.

After leaving the morgue, Bruce thought and said to Lex, "Generally, officers will choose the most convenient method for storing the body, and if there is no forensic hospital, then the body will be stored in the nearest hospital before the autopsy is performed. ”

"If they didn't put the body here, then it was possible that they were sent directly to the forensic hospital, you go back to Luther Manor to mobilize the surveillance of the crime scene, and tonight, I will go to the forensic hospital to have a look."

Lex has no objection to this arrangement, and he will allow Bruce to come here to investigate the case, just because he feels that he can borrow his power.

Lex himself is not strong enough, and when he encounters a murderer who is too fierce, it is fine if he stays in Luthor Manor, but if he wants to take the initiative to investigate the case, his safety cannot be guaranteed.

So, using Batman to go out to investigate in the field is a good option, anyway, the purpose of both of them is to eliminate the owl, and they have a common enemy in this regard, so they can cooperate.

As Bruce had arranged, Lex began to use technology to obtain surveillance of the crime scene, while Bruce went to the forensic hospital to find the body.

Bruce, who haunts the night, once again dons Batman gear, and he stands on the top of the Luther Tower, the tallest building in the metropolis, overlooking a city that is even more prosperous than Gotham.

The night sky here is far less dark than Gotham's, it is lit up everywhere, and Batman's vision is a little hazy, and he feels that he is not suitable to stay in a city like this, and that bats should belong to darkness.

However, as the wind reached his eyes, and the cloak turned orange with the warm light, Batman took a deep breath, then glided down, jumping from building to building, and finally reached his destination.

The Met's new hospital is located in the middle of nowhere, and there are only two gates on duty, and Batman didn't have much trouble sneaking in, but there are still no bodies here.

Batman senses the strangeness of the whole thing, so he searches all the hospitals in the Met, but no body is found, and finally, he ends up at the home of the Metropolitan Police Commissioner.

When the sleeping police chief was awakened, he looked in horror at the dark figure standing on the balcony, Batman stood in the shadows outside the window, and he asked in a deep voice, "What about the body of the murder?" ”

"I ...... I do not know...... Who are you? Stay back! I'm going to shoot! The police chief screamed.

Batman found that the police chief was actually not stronger than Gordon, the security of the Met was so good, and he had nothing to do with him, he was a very common kind of villain, bullying the weak and afraid of the hard, violence and money could pry his mouth open.

At last. Still, Batman gets the answer he wants from the police chief, who, according to him, is missing.

The steps to investigate the crime scene were only a few steps, and since the two bodies were located at the intersection of a busy street, the police had to quickly remove the bodies and restore traffic.

When the first body was found, because the death was too tragic to be seen by more people, after a preliminary investigation, the body was disassembled, covered with a white cloth, and sent to the hospital car.

However, the car did not drive to the hospital as planned, and according to the police chief, in the end, they found the missing car and the unconscious police officer in the suburbs, and the driver disappeared along with the body.

Later, the police found the real driver who had been knocked unconscious in the underground garage of the hospital.

In other words, the person who stole the body first knocked out the real driver, then pretended to be the driver, hijacked the car transporting the body, and finally stole the body.

After this happened, all the officers were vigilant when transporting the second body, and a detective personally drove the body to the forensic hospital, but just as Lex and Bruce arrived at the Met and went to the hospital, the body disappeared again.

There weren't that many people in the forensic hospital, and security wasn't adequate enough, so someone sneaked in and stole the body again.

Batman, who had found nothing, returned to Luther Manor, and Lex did not bring any good news, standing in the laboratory under Luther Manor, he fiddled with the computer and said:

"The security of the metropolis has always been very good, people here lack a sense of crisis, and there are very few surveillance cameras, except for a few major intersections, most of the cameras inside the building have too many blind spots, and some even have only one camera on the entire floor."

"I called up the surveillance of the crime scene, but apparently, it was not the first crime scene, and the murderer just put the body there, not there to kill him."

"The question is, how did he get the body there?" Bruce asked.

"Judging from the surveillance, the body should have landed from the roof of the building, and a parachute was tied to the chair that bound the body, and the body fell from the roof of the bank building into the crowd, and then caused panic."

"Unfortunately, the bank building is the tallest building in the vicinity, and the monitors of the rest of the buildings can't take pictures of the roof, and there is only one camera that captures a back."

Lex showed Bruce the image of a man in a blue cleaner's uniform walking through the rooftop door, but only a very vague figure could barely be judged by gender, and due to the angle, even the size and height could not be judged.

"What about the bank's internal controls?" Bruce asked.

"Metropolitan Center Bank has the most glass curtain walls in the vicinity, and they hire a cleaning company to clean the glass for them on the 3rd of every month, which is today, and since the glass on every floor has to be cleaned, there are cleaners all over the building."

"Through the internal surveillance of the bank, a total of 43 people were found, all of them were men, all wearing uniforms and hats, and their body shape and height were impossible to judge, that is, they were all suspects."

Bruce propped one hand on the table and said, "It seems that this murderer has been prepared for a long time, first read all the actions of these 43 people......"

"I had already analyzed it all before you came back, and I didn't find any suspicious behavior, at least in the places where the surveillance was filming, their behavior was normal." Lex replied.

"If the murderer was going to throw the body off the bank building, he had to bring the body in first, how did he get the body in?"

Lex chose a surveillance screen, played it for a while, pressed the pause button, and then pointed to one of the top spots, and said to Bruce, "...... Looking at this box, it is very troublesome to clean the glass curtain wall of high-rise buildings, and special aerial work tools are required. ”

"The fixing tools are often very large and have a lot of ropes, so they need to be transported to the building a day in advance and placed in the basement warehouse, that is, on the 2nd of every month, these boxes will appear in the warehouse on the ground floor of the bank building."

"As long as the body can be packed into these boxes and transported to the building's underground warehouse in advance, then these boxes can be pushed to the floor where he is going, and then under the pretext of cleaning the glass, find a surveillance corner, and throw the body down."

Along with Lex's description, Bruce and Lex work together to construct a scene in their minds.

Flipping to April 2, around 6 p.m., one cleaning company truck after another drove into the underground garage of the Central Bank.

Cleaners in blue uniforms lifted large boxes off the cart and carried them onto the trolleys and into the underground warehouse, which was connected to the underground garage.

One of the cleaners was carrying a box that was so heavy that blood oozed from the edges of the box, but the other cleaner didn't notice the details, and the two of them carried the boxes to the cart and pushed them all the way into the warehouse.

On April 3, at about 7 o'clock in the morning, the central bank officially started its office, and the employees walked in from the main entrance bustlingly, and at this time, the cleaners had arrived at the underground warehouse and pushed out all the prepared utensils step by step.

The murderer, dressed in a cleaner's uniform and pushing a toolbox, came to a certain floor of the building, then moved the body and equipment out of the toolbox, opened the glass, and threw the body down.

The picture pauses at this point, and Lex and Bruce glance at each other, and Bruce is the first to speak, "There's a problem here. ”

"That's right, that's the smell." Lex immediately said, "If the corpse were to be hidden in this kind of toolbox and carried to the warehouse with the cleaners, it would be impossible for no one to smell that terrible smell of blood." ”

Bruce immediately picked up the notebook next to him, he drew the form of the corpse, and then pointed to it and said, "This wound, and this wound, the bleeding is very large, even if the blood has dried up when he carries the corpse, it is impossible that there is no smell at all." ”

"There are two ways to make a corpse odorless." Lex immediately answered, looking familiar, and he said, "The first is to treat the corpse with special chemical agents, and the second is to use other pungent smells to mask the smell of blood." ”

"Now that the body is gone, we have no way of verifying the first possibility, but if we look at the second possibility, what can hide the pungent smell of blood?"

The two replied in unison:

"Cleaner for glass curtain walls."
