Episode I. The Plisetsky Monster. Pt. I

(…)Agents Katsuki and Nikiforov were required to meet attorney Yulia Plisetsky in her house in Los Angeles the 8th of the present month. She had received threats that could potentially put in danger the life of her son, Yuri Plisetsky or her father, Nikolai Plisetsky. When they arrived at the place cited above, they found a grotesque scene(…).

"A penny for your thought," Victor asked, noticing the nervous fidgeting of his partner on the passenger seat. "We can stop here and rest if that's what you want." They had been partners for a few weeks now. Agent Yuuri Katsuki was assigned to the special and classified division of the X-files after reports of weird behavior and inconsistent conduct, made by his previous partners. Agent Victor Nikiforov requested the change himself, surprising most of his colleagues at the bureau.

"I'm just worried what we might find this time," Yuuri answered with some hesitation, "Every case is worst than the previous. It's getting hard to look and not be affected."

"Try not to empathize with anyone less it's 100% necessary. That's what I do," Victor replied, eying his partner, "And if you need to step back, just tell me, alright?" Yuuri nodded, looking out of the window.

When they reached the destination, the first thing they noticed was the front door wide open and the superior part made of glass, was broken, the crystals scattered over the glass and foyer. In an automatic mode, both agents took their guns and prepared in case they need to fire. They split, Yuuri moving to check the basement, and Victor went to the first floor.

Yuuri descended the stairs that led to the basement carefully, only stopping when, at the bottom, found reddish footprints. The copperish smell instantly hit his nose. It was blood.

"F.B.I! Don't move!" Yuuri yelled when he saw a shadow hovering over a body on the floor. The shadow stopped and fell to its knees. It was then when he could observe that the body in the puddle of blood belonged to Mrs. Plisetsky, and her son was the shadow that accompanied her.

"M-my mom. S-she…" The blond teenager babbled. Yuuri lowered his gun and tucked it on his back, before approaching him. "It's okay, Yuri, I am here to help you," he grabbed the teen by his shoulders and helped him to his feet. The blonde had his hands and arms covered in bruises, and a purple mark bloomed on his pale cheek.

"Yuuri? Did I hear you yell.- Oh shit." Victor stopped dead in his tracks taking in the scene. "I'm calling back up. Take him outside."

Yuuri helped the minor to climb up the stairs, and led him to the small garden outside the property. He kept whispering something unintelligible, but any attempt to have him talk was fruitless. Minutes later, an old car arrived at the house, and Nikolai Plisetsky descended the car. "Yuratchka, what's going on?" He asked, and Yuri rushed to his side, hugging him. "I told her the monster would come for her, but she didn't believe me! It's my fault! It's my fault!"

An ambulance and a police car arrived and a paramedic approached them. Victor stepped out the house, holding a plastic bag. Before Yuuri can ask what he had in his hands, Victor said, "Hey, Yuri. Can you go with the lady and with Yuuri, please? Your grandpa will be with you in a moment."

Resigned, Yuri nodded and followed the paramedic and the agent to the ambulance. Once he was alone with Nikolai, Victor started, "I am Agent Nikiforov. My partner is Agent Katsuki. We found your daughter's body in the basement. She was killed." He took in his reaction, or better said, the lack of reaction from the father of the victim. "Your daughter called us a couple of days ago. Apparently, someone had been threatening her. Were you aware of this?"

Nikolai decided to remain in silence, arguing that his grandson needed him. Victor couldn't stop him. He looked at the ambulance and saw Yuuri crouching at the feet of the teen. Surely, he was trying to get something from him, too.

Without any luck, Yuuri stood up and walked over to Victor. "Did the boy tell you anything?"

"Not at all. He kept repeating that the monster for her and it had been his fault. Not sure what that means. And you?"

"Mr. Plisetsky refused to talk. I called Phichit. He'll be here as soon as possible."

"What do you have there?"

"I found a shirt and pair of sneakers hidden in Nikolai's bedroom."

"And?"

"The shirt was drenched in blood, and I am certain the soles of the sneakers match with the bloody footprints in the basement."

They stared at each other for an instant and then moved their attention to their Plisetsky's. At first glance, the grandparent seemed clearly worried, but not like someone would react if they find out their daughter had been killed. He sat with Yuri, consoling him just like a grandparent would do.

"The boy has bruises in his arms and face, but they are fading. He presents signs of physical abuse, but nothing recent." Yuuri stated, handing a small notepad to Victor with his observations.

"Mr. Plisetsky didn't seem fazed by the news. His main concern was his grandson. There's something… Off, Yuuri."

"Let's go back to the basement and see if we can find something else."

(…) The body of the victim doesn't present signs of struggle. The attacker of the victim, torn the victim's neck, causing her a hemorrhaged, which is described by the forensics as the cause of the death. However, the marks of tearing around the neck and chest of the victim are similar to those caused by the claws of an animal and not by the hand of a man (…)

"Let's wait for Phichit outside, alright?" Victor suggested, and Yuuri nodded. He stayed behind, looking around the basement as the lights turned off, leaving him in complete darkness.

"Victor?" Nervously, Yuuri asked, but got no response. He tried to make his way to the stairs when he stumbled with something. He fell down, hitting his head on the process. Yuuri cursed loudly, and then he tried to get up, but something stopped him. He couldn't see anything, but he could feel the presence of someone else in the basement, someone who was approaching him. A sharp pain shoot through his body when someone grabbed his arm. He managed to break free, and then the lights were on again. Victor was back in the room, running down the stairs.

"Yuuri? Are you alright?" He questioned the young agent who could barely nod. In front of them, was Yuri Plisetsky, looking lost for a moment.

"Yuratchka, come back up!" the voice of his granddad caught his attention, and Yuri left the basement.

"Yuuri, what happened?"

"I'm not sure, Victor. The lights were off, and I stumbled and hit my head. Then something grabbed my arm. It felt like something sharp, but I'm sure I was hallucinating."

"Yuuri, look at your arm."

In his arm, agent Katsuki could see the imprint of a hand and three -thankfully- not so deep cuts in his arms.

When the forensics arrived, Phichit compared both his injured arm and the victim's neck.

The same person who killed Yulia Plisetsky had attacked him.
