there is no words to apologize for all those weeks without a new chapter, however I will give it a try. guys, my few followers, I'm really sorry for this delay on the story, but I had been really sick lately and had been under the influence of strong medicines that did help with my writing. If you remember Castle under the influence of medicines during 05x19, well, I was way worst.

hope you enjoy this chapter and i promise a new one soon.

kisses

Chapter Four

It was just like she had been replaced at that moment. It was just like one of those magic tricks where the magician makes his assistant disappear and, in the following second, another woman shows up on her place.

The Katherine Beckett that had almost cried when she was talking about her dad was long gone and was replace by some unemotional, cold and fearless creature, incapable of feeling anything, not even the slightest shad of any kind of feeling out there. Her eyes dark and cold, while all her muscles seemed to tense up.

The Monster had taken place. Full of rage and despise.

They had told him about that. They had descried him what she would become when the other thing took place. He had read the psychiatrist report where her "condition" was described as multiple personality disorder. That whenever The Monster took over, every shred of the kind and good portion of her personality was gone.

Whenever The Monster took place. Kate Beckett, honored police officer, incredible friend, devoted daughter, was gone.

"Don't fear me, Mister Castle. I don't kill innocent people and, as far as I know, you didn't do anything wrong, did you?"

They said psychopaths can smell fear, and Castle was almost believing that to be true. When the change came, it scared him like hell. Yeap, she had already acted maniac earlier on the interview, but not at this level.

"Who are you?"

He manage to ask, his words weak and scared, almost failing.

She laugh. A weird laugh. A crazy laugh.

"What a silly question to ask Mister Castle. Thought writhers where masters with words."

He was getting more and more afraid after every single word she spoke. The way she spoke every single word sent chills under his skin. The evil smile on the corner of her lips terrifying him even more.

"It is me. Katherine Houghton Beckett, or Kate to my friends, Captain Beckett or just Beckett to my subordinates, Katie to my dead parents, K-Becks to my college friends, Kit Kat to an old boyfriend. Born in November 17, 1979 in Manhattan. Federal inmate number 41319, which is the same number of my badge. Execution day May 11."

Silence.

"You are not Katherine Beckett."

"Of course I am her…"

She stared at Castle and he could see the craziness in her eyes.

"Well, I am the other her. The one that kills. She is always back and forth with my name. Sometimes she calls me "that voice" others, "the monster". I kind of like the last one better."

She over exaggerated when she called herself "the monster", really proud of the nickname.

"I suits me."

Castle was silent. He was considering what to say next. His time was almost over and he needed to put every single second to good use while "The Monster" was on. He needed to extract everything possible from the other one, not knowing if it would happen again.

"Why?"

He asked. Reluctant first.

"The second personality? Why you?"

"Katie is too nice to kill anyone, so I take over. Every time she shot someone before all this started, it was me who was pulling the trigger. Not her. I have always been there, locked inside her mind. The devil voice on all the good and bad struggle. But… When she freaked out, I started to take over. When she lost the bettle…"

"When did it started?"

"It was when Dick Coonan got out. He practically confessed being involved in mom's death. On her way home, she paid a visit to a liquor store and bought a bottle of scotch… Drank it all while crying and struggle with the need to make justice. So… I took place. I found him that night and started putting every piece together. I got some answers from him… but he died before I could get the name of the person behind. Then, a guy that killed a little girl was considered innocent because one lab tech fucked up. I needed to do to him what he did to that little girl."

She looked to the guard on her left then back to Castle. She wanted him to reassure her she still had time.

"Scott Dunn. He killed a little girl. He raped her for three days before he actually decided to spare her life, killing her with blows to the head. Multiple trauma to the head and torso, was what Lannie, the coroner said on her report. She was his sister's daughter and he was taking care of her wile her mother was travelling… I found him a placed him on a bed with his ass up… I gave him the opportunity to choose which object he wanted to be inserted on him and when. Then, after three days torturing him on the worst ways possible, o took my bat, the same one I used latter on Martin, and I started to brake every single fucking bone on his body."

Castle swallowed hard. His overactive imagination starting to take a toll. He had seem the files from Scott Dunn's case. What he had done to his little nice and what Beckett had done to him… he could picture everything as if it was being portrayed right in front of him. The way she would have tortured him. The way she would be smiling while swinging the bat. The sound of his bone braking. His screams. Him begging for her to stop…

She disgust him right now. She really, really disgust him at that moment. He couldn't believe how someone could act like that. How a person, a human being, could do what she did to another person. There was no way to justify the things she did, there was no way to justify her brutality, her lack for compassion for the other.

No matter how was the other person. He couldn't accept the things she has done, not even considering them as vicious criminals, they ended up becoming victims and she, she ended up becoming one of them.
