The trio along with Lestrade entered the lockup. Rosie confirmed this was the place that she was held captive. They walked into the room on that they were transmitting from…empty. Absolutely nothing that could link Moriarty or Rosie being held here. But Rosie remembered what the lockup looked like from the river. Rosie stood outside the door she was held in. She put her hand on the door handle and then took it off again. See did this a couple of times before John came up behind her and out his hand on her shoulder.

"You don't have to do this Rosie."

"I want to. I can't be afraid for the rest of my life. I need to find out the truth and to do that I have to take risks."

Rosie opened the door. Nothing. Except a note in the middle of the floor. Sherlock picked it up.

You'll hear from me again…maybe not straight away….but you will hear from me again.

"Dad?"

"He's gone…for now. Mycroft, as best you can track him down. We need to know what he's up to. I don't know if this means no more bodies for as long as he's gone or whether it's just him we just need to an eye on whatever is going on."

"I think I recognised him. The guy who attacked me. I've seen him before." Rosie said amongst the silence.

"You've Sebastian Moran before?" Sherlock was excited.

"It was the day I came to stay with you. I came into John's surgery. I'd been beaten up by someone but I was never able to remember his face. As hard as I tried I could never picture his face in my mind. But then yesterday when came in and hurt me, suddenly it all came back to me. I remembered my attacker because he was stood right in front of me, ready to hurt me again."

"This is brilliant. Fantastically brilliant." Sherlock said as he excitedly paced around the room.

"Sherlock, would you care to enlighten us? You know seeing as it might help us." Lestrade asked.

"Isn't it just convenient that my daughter that I've not been allowed to see for 10 years ends up living with me after he mother winds up being killed and then becomes heavily involved with my latest case along with her mother's murderer. It all started when Moriarty walked into her life, however many years ago. But six months ago, when he came back after being away, wormed her back onto the drugs and used that to get the video and audio that we heard. Then once he got her addicted he used that and began turning her mother against Rosie and making her feel worthless and that she was a burden on her life. Rosie was left with no family and she couldn't bare being in that house she began living on the streets, she had the money that mother had so she could afford clothes and some degree of food. The first murder occurs on the day that Rosie is attacked which happens to be near John's surgery on a day that John and at a time only John was working so that she would have to see John. The attacker ends up being Sebastian Moran, one of her mother's killer's henchmen. Now what does this suggest to me? Moriarty always wanted to reunite me and Rosie and have her living with me because we all know how caring you are you wouldn't let her live on the streets, so you brought her home. You originally thought about calling social services but thought against to see if you would let me with us so you could keep an eye on her, but it was dependent on whether or I was concerned…which I wasn't especially after I worked out who it was. Now that she is living with her father and having a brother like Mycroft means that social services won't be bothering us anytime soon. Obviously, if Rosie is living with us she'll be visiting crime scenes with us and what's a perfect first case to taunt her with? The death of her mother," The faces on his shocked flatmates. He finished. "There is a lot of chance work in what I just said but I think Moriarty got exactly what he wanted."

"That was bloody amazing." Lucy said wonderstruck.

"It was just all pieces of a puzzle fitting together." Sherlock grinned.

"Sherlock…. come and have a look at this." Lestrade called.

Sherlock rushed into the room Lestrade was calling from. Lestrade had a box in his hands. He pulled out two serrated knives.

"Anderson get them examined see if they match our victims blood, but you won't be finding any fingerprints however because they would have been clean. But its still a good start finding out whether or not those blades were actually used to kill those people."

"What do we do now?" Lestrade asked

"We wait. We wait for another body for him to strike again because he is bound to." Sherlock said excitedly.

Weeks passed and nothing. Rosie was lying on her bed when suddenly she received an anonymous text message.

I want to see you later. Meet me at Regents Park at 12 0'clock…. don't tell your little friends though. Don't want them spoiling our fun xxx

Rosie sat and reread and reread the text message over and over. She stood and paced around her bedroom thinking about the text. Should she go? Was it trap? Was she going to make it out alive? She got dressed and suck out window and dropped onto the street below without passing any suspicion. She got into a taxi and drove over to Regents Park.

John went and knocked on the Rosie's door. No answer. He knocked again. Still nothing. He pushed the door open.

"Lucy?"

No answer. John went to find Sherlock.

"Have you seen Rosie?"

"Not since yesterday. Why?"

"Well she isn't in the flat."

Rosie sat in the taxi and felt her phone vibrate countless times against her leg…she ignored them. They realised that she was gone pretty quickly then. She was a dead girl walking if she got out of this alive. She pulled up outside Regents Park. She looked at her phone…17 missed calls. Then another text.

Meet me by the open-air theatre xxx

Lucy walked through the park. It was a beautiful day the sun was bright, not a cloud in the sky. She walked past a smiled at several people. She then found herself at the entrance of the theatre. She rounded the corner to climb up into the auditorium. She was greeted by an all too familiar face…Jim Moriarty in his dress suit.

"Rosie! How nice to see you. These are much nice circumstances than the last time. I knew you wouldn't be able to resist a text message from me. Come take a seat." Jim sung.

Rosie confidently sat down beside Moriarty. "What do you want?

"My, my you don't like hang around do you. You are so much like your father. Just not quite as psychotic."

"My father is not a psychopath. You're the psychopath here."

"Feisty too. I'm not trying to hurt you Rosie. I just need you to see things for what they really are." Moriarty tried to hide the smirk.

Rosie felt some anger rising within her. "What's the point of this then? Why kill those innocent people? Why scar my physically and mental? Why taunt me with your games? If you didn't want to hurt me, why do what you did to me? Why remind me of what you did to my mum?"

Jim laughed. "I never did any of those things. Anyway, your mother was pathetic. Despite everything that happened she still came crawling back for more didn't she."

Rosie was frustrated. "You think this is some sort of sick game to you. My mum what you were, and you didn't like that. That's why you killed her, she was too close. Now your tormenting me to get back at her. What's the point? She dead and it's not working."

"Well," he was debating something. "I actually think I'm quite funny. Real kick this is."

"You're insane."

"Thank you," He went to stand up but then sat back down again. He drew something from his waistband and place it in Rosie's lap. "Your mother wanted you to have this."

Rosie picked the gun up. She gasped and held back a sob. She ran her finger across the engraved writing.

This gun, my love, should maybe be used on yourself

Rosie fought back the tears. "My mother did not think those things."

"I heard different."

"How are you doing this?" The anger still rising.

"I have my ways. You should know this now. But what you do need to know is your mother never loved you for a long time. Get that into your damaged head. You won't win…it's too late for that now. We aren't going to play a game anymore. You're weak.

You can solve all the murders in the world, but you won't be say I did them. So, you, Sherlock, John can carry on solving them but its all for nothing. They'll just keep on coming. Its all going to end in heartbreak for you and your friends," Moriarty stood up and adjusted his suit. "Give up now whilst you're ahead of the game. Just give a message you're ready to give up," He began walking down the stairs and then turned on his heel. "That gun it's a message from mum. Don't be so dull and ordinary." He carried on walking.

Rosie called out to him. "If you think I'm going to end it all your very, very wrong."

"We'll see," He carried on walking and sung back. "We'll see…."

Rosie sat uncomfortably on the seat. She checked her phone – 17 missed calls had suddenly doubled. She walked back through the park and began listening to the voicemails. They were worried both John and Sherlock. She couldn't go home and face the shame, that's what she'd made John and Sherlock look like fools.

She began to cry. She just walked around the park to clear her mind but I just wasn't walking. She walked out the park and onto the busy London streets. She soon clocked a black car that he'd been following her since she left the park. She turned down a side street and eventually stopped. The window rolled down and Mycroft beckoned her into the car. Rosie climbed in.

The car pulled up outside 221B. This was it, time to face her demons.

She walked into the living room and the dams gave way and she just broke down in front of John and Sherlock. She collapsed to the floor in a ball. She calmed herself and explained what happened. She placed the gun on the table.

"Sherlock what do we do?" John worried.

"We carry on playing the game. Its not a simple as he's making it out to be."
