1st October 2011.

"Sherlock, have you seen Nark?" Lestrade asked. Sherlock shrugged and looked up at the house, "I think she went inside." Lestrade nodded before making his way towards the house. Sherlock followed behind, she probably had some new incited on one of the bodies inside. Sherlock went through a couple of rooms before running up the stairs to where Lestrade had disappeared. "Lestrade?" He called, Sherlock waiting a few moments before making his way into a few of the rooms, looking for the body or Lestrade. When he reached the fifth room he saw a sight he was not yet accustomed to. Miller was laying on the ground her hand pressing hard against her stomach and chest, Lestrade was leaning over her, trying to keep her awake. Sherlock pulled out his phone and typed quickly.

Sender: SH
Recipient: John Watson

Upstairs. Now.
Floor 3. Room 5.
Bring a medical kit.

John Watson was chatting up one of the female police officers before he received a text from Sherlock. Almost immediately he made his way to the back of a police car, grabbed a first aid kit and ran towards the house. As John was running he was thinking of the sort of things Sherlock could have done to require first aid attention, at the top of the list was that he had cut his finger on paper. John rolled his eyes and reached the top of the stairs before racing into room 5. Instead of seeing Sherlock holding his cut finger, he saw Miller on the ground; blood rushing profusely from two bullet wounds on her torso, another deep abrasion was on her thigh that looked like it contained tetanus. If he wasn't fast, Miller was going to die.
"Lestrade, can you move away from her, and I'll try to help her." The Detective Inspector nodded before slowly moving away from her and leaning on the wall for support. "Sherlock call triple nine." Sherlock started dialling into his phone the numbers and then handed it to John.
"Hi, I'm at 249 Liverpool Street. I have a female in her twenties with two gunshot wounds on her torso, one on her abdominal area and the other; well it seems to be too close to her heart not to cause worry." Lestrade took in a shaky breath before running a hand through his hair. "Lestrade, how long ago did she stop breathing?" The Detective Inspector looked at John and his eyes widened, "I didn't I-I don't." He stuttered, fear overcoming him. "The patient also stopped breathing, her pulse is still there, slightly, and I don't think I can perform CPR without pushing the bullet into her heart, what do you suggest I do?" John asked the person on the other end of the phone.
Soon enough the ambulance arrived and Miller was taken off to hospital, still unconscious.
"Are you okay?" John asked Lestrade. "Yeah, yeah. I'm fine." He replied. John nodded and made his way down the stairs, his hands coated in the young girls' blood he washed them in an outside tap.

Sherlock was still standing in the room where Lestrade had found Miller, he moved slowly around the room before looking out the window and spotting something in his peripheral vision. He walked over to the ancient book shelf and took the piece of paper that was wrapped up in a ball before opening it.

I will burn the heart out of you.
