Chapter-

It was just another day at 221B Baker Street.

John lounged on the arm chair reading an email. While , studying Sherlock as he scrubbed the blood off a sliver letter opener. "His Sister." Sherlock said setting the small knife on to the kitchen table. "Sorry?" John asked looking up from his laptops laptop, which he had been currently reading his emails. "His sister. James Harrison's sister killed his wife."

"And how do you know this?"

"Well, it's quite obvious."

"Let me guess, the knife was specially made in India, on March 5, 2009. You tracked her travel records and found she bought that knife on her trip to India and brought it back here and killed her brother's wife."

Sherlock looked shocked "is that what I sound like?" john ignored the question, "well how do you know, Sherlock spit it out."

"Our murderer is not very smart, you see. It had her fingerprints all over it."

"Are you saying that jokingly or seriously?"

"Seriously, do I ever joke?"

"You have your occasions."

Sherlock picked his phone up, texted lestrade James Harrison's sisters house bring the police. He slipped into his coat, tied his blue scarf and started to the door. John put his coat on and followed behind patting his side to reassure the gun was still in his pocket.

Outside Sherlock hailed a taxi. London was coated in the usual dark smog that was known as a 'part of the landscape.' Sherlock stared out the window at the passing buildings. johnJohn was texting his latest girlfriend June Bryan, a young red haired women that john met at a small café joint on the corner, he found it that they hit it off. He finished his text, and looked up to see Sherlock looking at him strangely. "Well, aren't you going to ask where we are going?" "No, I was not. We are going to James Harrison's sisters flat."

"Humph. Well aren't you snippy." Sherlock opened the door as the Taxi came to a halt in front of a small brown home. John got out after Sherlock. The policeman and Lestrade where waiting outside. Lestrade was in deep conversation with Anderson "because son, Sherlock has no reason to kill me." He said "this could be a trap." Anderson said back. "Ah, look it's our favorite psychopath, right now." Sherlock and John walked to them "sociopath, high functioning sociopath, Lestrade, get it right."

"Do you have any reason to kill me?"

"Well…"

"See Anderson, he does not."

Sherlock started towards the house, knocked on the door. A women in her late forties with sharp features and brown hair opened it. "That's her." Sherlock said and moved out of the way as two policemen cuffed her wrists. She sobbed as they walked her to the car. "How…how did you find out? I did it. I confess, I'm sorry….I'm so sorry." Lestrade followed behind her "we put Sherlock Holmes on your case, he's our best."
