História Winchester's go to London - Another murder:

Lestrade came over to us with the triangular blade and apparently with some news. He handed us the baggy that held the triangular blade. Lestrade said "Apparently, there has been a third killing."

"Where?" Sherlock asked while examining the blade.

"Laurenston Gardens. Single murder like the first two. Same motive and everything. Two FBI agents are waiting at the scene to talk to you."

"Give me five more minutes with this scene. I won't go in a cop car. John and I will take a cab there."

"Thank you." Said Lestrade before turning around and leaving.

     Sherlock stood at of the bodies feet. From where I stood it looked like someone stabbed this girl in the back. So she was taken off guard. However my deductions were always wrong. I came to my own conclusion that we were looking at killer who loves to stab its victims to death. Possibly to release some pressure or get some anger out.

"What do you got so far, Sherlock?" I asked out of curiosity.

"We are looking at a woman, 5'4" to be precise who appears to be left handed. Don't say Nothing, John."

"I was thinking about to say anything."

"And there it is. Anyways, where was...Oh yes. The way she killed her victim was ultimately by surprise. See how the blade was pushed through the back of the neck...So possibly a grudge against her. John I want you to look up everybody that had grudge against our victim here. Somebody than had to feel remorse because I wouldn't have crossed the arms over her chest. Also look up all her friends."

Just when Sherlock was about done...Lestrade came over. He said "about ready?"

"As ready as I ever be. Who will I be talking too?"

"I already said that...Two FBI agents. They need to ask you some urgent questions about the murders."

"John, keep them busy. I have no time in talking to agents."

"Well that is a shame because they wanted to talk to you both while your together working on the case."

."agents are so boring though. Give me at least the CIA or Secret Service, but then again the are also boring. What is the true purpose of being a secret service member when people know all about them?"

"Don't know that question, Sherlock. Ask them why."

     Lestrade got into his cop car while Sherlock and I got into the cab that was waiting for us. Then we sat and rode to our next crime scene.
