"Vigilantes?" Brock wondered, "Like Batman?" ”

"It's a little different, at least we know that Batman doesn't kill people."

"Well, then I guess it's time for me to ask how do you know?"

Roy lifted a bunch of keys and explained, "The deceased man had a keychain hanging from his waist, and we can see that most of his keys are hanging from the keychain, but he also has a key in his pocket that is not attached to the keychain alone. Why? ”

"Yes, the stunned guard said it." "The gangsters knocked him unconscious when they came in and took the keys he kept. ”

Roy said: "Yes, then if, according to what you say, the murderer and these two gangsters are in the same group, then the problem arises." Now that they've got the key to enter this room, why would they use brute force to tear the outside door open? ”

Detective Bullock was speechless and had to admit, "Well, then that doesn't seem right. ”

"Plus, one more thing." Roy said, "We can see that the two dead people who were killed had guns in their hands, right? Can we assume, then, that if there really was a third life accomplice, the one you presumed to be the murderer, he was also armed with a gun? So since they had an infighting, both deceased took out their guns, but the murderer chose to kill them with brute force with his bare hands instead of using a gun. ”

"Or maybe he's just confident in his power and doesn't want to use a gun." Bullock Road.

"It's possible, but it's usually easier for you to use a gun."

Bullock asked again, "You know, the world of criminals in Gotham is not much simpler than ours, and criminals who have the ability to kill two armed men with their bare hands abound. Why don't you think it's the result of a gang fight, but the work of a vigilante? ”

"Intuition." Roy said dryly.

"Intuition?" Brock repeated incredulously.

Roy nodded, "Yes, intuition." That's it, by and large. But in more detail, I think the killer should be working for a vigilante I am tracking down who may be a bit of a homicide. ”

"May I hear his name?"

"Actually, it's 'her.'" Roy said, "Codename is 'Fallen Knight'. ”

Brock shrugged: "Never heard of it. ”

"Hardly anyone has heard of it."

Roy got up, walked out of the room, and walked out through the door onto the street outside.

The streets were full of traffic, people came and went, and there were a large number of onlookers in front of the door. About twenty meters diagonally opposite the gate happens to be an intersection, and a traffic light stands on one side of the road.

Detective Brock followed. Roy didn't look back at him, and said, "That place, there should be electronic surveillance video, right?" ”

"yes."

"Working at night?"

"Yes."

"So if they came in through the main entrance, the surveillance footage must have been captured?"

"We've already thought of this." "But no one came in through the main entrance last night. There was a hidden side door in the back alley that few people knew about, but our two robbers and the murderer seemed to know. The lock on the side door was picked open, and it looked like they were all getting in from there. ”

Roy nodded, and walked briskly down the aisle to the back door of the wooden door.

He checked the lock and commented, "This guy who picks the lock isn't very clever." ”

"Oh?" Detective Bullock wondered.

"Not as smart as me."

Roy said, surveying the alley outside. The alleys are dirty, no one has cleaned them for many years, cobwebs are knotted in the corners, hanging on the street lamps, and although the street lights are not on now, it is easy to imagine how dark this place must be at night.

Directly opposite is a tall residential building. Roy looked up, and suddenly there was a twinkle in his eyes, as if he had found something.

"How?" Brock asked.

"Nothing. Staying here is not expected to find anything more, and I think there may be a little clue, but I'm not sure, I'm going to use my own methods to investigate. ”

"Okay." Bullock said, "Then get in touch again." ”

In the residential building opposite the murder scene, Roy came to the elevator at the bottom of the building, counted the floors and pressed the button on the twelfth floor.

Taking the elevator to the twelfth floor, he stepped out of the elevator and looked left and right, then went straight to the door of a house and knocked on the door.

A young man dressed in scruffy clothes with unkempt hair opened the door and asked, "Who are you looking for?" ”

Roy glanced at him from head to toe and asked, "You live alone?" ”

The man was stunned for a moment and said, "Yes, what's the problem?" ”

Roy said: "I'm Roy Green, a detective consultant at GCPD, and there was a homicide last night across from your house, and I'm investigating this matter and want to ask you some questions about it." ”

"If you're asking me if I saw or heard anything strange last night, I'm sorry I can't help." The man shrugged, "I went to bed early last night, and I guess I slept so well that I didn't hear anything. ”

"." Roy said unceremoniously.

"What?" The man frowned, wondering if he had misheard.

Roy said, "Don't try to pretend to be confused. I can always see more things than others, but I don't need this kind of talent for the average person to see at a glance that you are a sloppy, unruly guy, careless and careless, and even don't remember to put away the tools and evidence after the voyeurism. I can see the telescope in your window from the alley downstairs. ”

The man's face turned rather ugly, and he coldly spat out a word: "Get out." ”

He tried to slam the door hard, but Roy pressed his hand against the door with great force to stop him from closing the door.

"But you're lucky, I'm not here to catch the voyeur." Roy continued, "I just think if you had been looking through your binoculars last night at the good view of the bedroom across the street, as usual, I can venture to guess that you might have accidentally seen something in the alley below. ”

"You're." The man panicked but still didn't admit it, "I'm an astronomy enthusiast, are you slandering me for peeping just because I set up a telescope to look at the stars?" ”

"First of all, you're not an astronomy enthusiast at all, and that's not an astronomical telescope at all. Second, no one will point a telescope diagonally down to look down at the stars. Roy breathed, "However, I'm glad that your voyeur target is lower than your house, because then you have to look down to have a better chance of seeing clues about last night's case." ”

The man gritted his teeth: "No comment, let's talk about it with a summons." ”

"Of course, you know that when I apply for a search warrant, it will be enough for you to destroy evidence against you. But maybe I don't need the help of the courts to achieve the threatening effect. "For example, if you call the owner of the sugar company and tell him that his employee is suspected of breaking the law by voyeurism, whether I can prove it or not, as long as the rumor spreads in your company, I don't believe it will do you any good." ”

The man's face was shocked: "How do you know?" ”

"It's not a good habit to throw your shirt on the sofa in the living room, with the initials of your company name written on the sleeve near your shoulder."

Seeing that the man had been completely shaken, Roy hit the railroad while it was hot: "However, the good news for you is that I am only a detective consultant, not a policeman." I am free to choose whether the clues I have gathered in the course of handling the case are useful to the case, and whether I have to tell the police. So why not make a win-win deal? Tell me if you saw anything last night, and I won't tell you. Stop trying to be fooled, I can see you lying. At first I was just guessing what you might have seen, but after a few words I told you, I'm now sure you have a clue. ”

The man hesitated for a moment, then said, "Yes, I saw a woman coming in and out of the door of a dark door in that alley. ”

"How much do you remember about that woman?" Roy asked hurriedly.

"Not impressive, but," the man hesitated for a moment, "I have the video." ”
