Roy returned to the apartment, looking visibly more depressed than he had been when he had gone out.

"As a result, the biggest takeaway from this operation is that we know that the Joker knows the impostor." "But it didn't help. He didn't want to give any clues, and it wasn't so easy for us to get him back for interrogation. ”

"Have fun." Barbara laughed and said, "It's not for nothing. ”

"Did you find anything?"

Barbara's fingers flicked quickly on the computer keyboard and said, "After you left, I did a comprehensive investigation of the surroundings of this makeup factory in Kington, and it turned out that I made an unexpected discovery when I visited the computer in the Batcave, well, I guess I need to thank Bruce for giving me access to the bat computer at any time." Look at. ”

Roy leaned over to her screen, which was displayed at a touching resolution, but vaguely visible was the front entrance to the Brandon processing plant.

"Security cameras?" Royloy was a little curious, "Why are there surveillance cameras in such a place?" ”

Barbara explains, "Bruce installed a lot of his own cameras in Gotham City while he was investigating the Gotham case. Of course, compared to general road surveillance, Batman's surveillance cameras are extremely hidden, so the people who are photographed are not aware that they have been filmed. ”

She dragged the progress bar with her mouse and quickly paused.

A young man in a gray jacket, dark blue jeans, and a hood appears obscenely hunched towards the gate of the makeup factory, with his collar raised as if to cover his face.

"I used facial recognition software to confirm the person's identity." Barbara said, pausing, "Well, I may have borrowed some of the Gotham Police Department's database. ”

"How did it turn out?" Roy couldn't wait to ask.

"Mitchell LaVine." "Staying in an apartment in Ryker Heights. ”

"Very well, then let's visit him now."

Roy regained his strength and was ready to strike again.

"Or you can start by saying, 'Thanks, Barbara, you've been really helpful,' or something."

Roy was stunned and looked at Barbara with rather strange eyes.

She suddenly regretted saying this, and said with a crimson cheek: "Alas? What are you looking at me like that? Sister is joking, go quickly, go quickly. ”

Roy smiled.

"Thank you, Barbara." He put his mask back on, "Great help." ”

Then he jumped out of the window again and disappeared into the night.

Barbara winked twice in the direction of the window and said to herself, "You're welcome, you're always available." ”

Reich Heights, Mitchell LaVine's apartment.

Roy carries on the good tradition of the Bat House - never going through the front door, priing open the balcony window and climbing through the window. It's a very dark room, not only because the lights are not turned on at night, but even during the day, I'm afraid it's a dark corner, because the lighting in this room is really poor.

This looks like Mitchell's bedroom. There was a computer on the desk, and the desk was messy, but the books on the shelves were neat. At a glance, it was clear that someone else had helped him organize the shelf, and he rarely turned over the books on the shelf, and he himself was a man who never cleaned up.

Such a person rarely folds the quilt when he gets up, but his bed is neatly made. No, it should be said that there was no trace of sleeping for at least a day.

The bedroom door was closed, and Roy gently pushed a crack open from the inside, peeking out. Outside is the living room, and orange lights illuminate every corner of the living room. Three cheap couches were arranged around an open television, and Roy's view of the TV was facing away, but he could see what was going on the three couches. The TV was on, but no one was sitting in front of it.

Roy gently pushed the door open, and at all times at a 360° angle to guard against any possible sneak attack, his steps were inaudible.

There was no one in the living room or toilet. But when he unscrewed the handle of the other bedroom opposite, he saw a lamp on the table and an armchair with his back to the door. It looked like someone was sitting in a chair.

Roy pushed the door open almost without a sound, slowly approaching.

The man didn't react in the slightest.

Roy gently walked over to the front of the man, but she still didn't respond.

Of course, she couldn't have reacted any way.

Roy pressed the headset and connected to the communication: "Barbara? I didn't find the killer, but I did find that his second victim might have been his mother. ”

Barbara's dossier to Roy soon confirmed Roy's suspicion that the old woman was indeed Mitchell LaVine's mother.

The old woman's eyes widened, and a look of horror and disbelief was forever fixed on her face, and long blood streaks stretched out from the bloody hole in her forehead, which looked very hideous and terrifying in the faint light of the lamp.

"But I think we have a way to find his next victim." Roy said suddenly.

"Oh? What did you find? Barbara shared Roy's perspective, but she didn't find anything.

"You see all the things in this room," Roy said, "almost everything is very neatly arranged, and most of it is strictly symmetrical. This may be the special temper of this lady. Look at this photo wall again. ”

He said as he turned to the photo wall beside the deceased so that the camera in front of him could take a picture of it.

The photograph posted on the wall shows a man and a woman posing with the two men. Strangely, however, the photographs were not neat, or it should be said that some of the photographs in the middle that could have been neatly arranged had been torn away.

Barbara was also quick to notice: "You mean, Mitchell, he tore some of the pictures off the wall?" ”

Roy nodded and said, "And it can be speculated that these photos he tore away contain his own, because you can clearly see that none of the remaining photos contain Mitchell." ”

"So why did he do it?"

"My guess," Roy said, "should mean 'goodbye to your old self.'" He wants to cut off his past, like a clown, and become a complete madman with no past to trace. ”

"So now I need you to find out the location of the next person who is most closely related to Mitchell, and he is likely to have gone towards that person." Roy continued.

"This one is pretty easy to find." Barbara quickly replied, "His father is in prison right now and can't go anywhere." ”
