"Sherlock, we need to go to bed. You need to go to bed. You haven't slept in three days." John sighed as he fell onto the couch and watched Sherlock pace.

"Sleep is for those who have nothing in life to look for. I will sleep when the case is over." Sherlock replied as he went over the notes they had on the case.

Three days ago, Lestrade, the only DI who is willing to ever work with Sherlock, contacted John about four murders that had the Yard scratching their head.

"There's something tying them together John, but what?",Sherlock moved to the kitchen to retest the soil from underneath Victim # 2's nails

John rolled his eyes and got off of the couch to look at the medical notes of the coroner, knowing that if he didn't try to help Sherlock would just get worse.

"The only similarities between all of the victims Sherlock is that they are women and their ages range between 17 and 21. You've been at this for days and haven't gotten anything new. You need to sleep or you won't be of any help at all."

As soon as John finished his sentence, Sherlock looked up with a gleam in his eyes.

"John! You amazing man you!"

John sighed,"What did I do now?"

"You solved this case! All these women have nothing in common correct?"

"Yes…"

"Wrong! They all helped."

At this point, John had gotten tired of the back and forth between the both of them

"What the hell is that supposed to mean Sherlock?"

"Each woman volunteered at the same clinic within 3 miles of each dump site, we knew that, it was in all of their files. However, who they helped at the clinic was not. We only found that out from the leading all helped the same person."

John shook his head as Sherlock explained.

"Yeah, but the Yard questioned hi-"

"But they didn't! They questioned his brother! You could tell by the way he reacted to the questions and when they said his name. No they questioned his twin brother, but not him.", Sherlock interrupted John.

John, being used to this, just went on and asked,"If that's the case Sherlock, then where is he?"

Yet again, a gleam entered Sherlock's eyes,"Where do you think?"

Horror started to show on John's face as he started to piece it all together.

"No! He wouldn't. Would he?"

"It's his hunting grounds John, of course he would go back to the clinic."

Running to the phone, John began to speak to himself,"I'm getting Greg. This has gone on long enough," in a louder voice he asked," Do I need to call a cab?"

Sherlock replied as he put on his coat,"No,We can get there faster if we walk. We need to hurry though, before he finds another girl."

John sighed and ran his hand his face, "When this is over, I'm not leaving my bed for a week."

"Agreed."

NA:I know this doesn't really sound like the boys but when I wrote something like this for my grandmother it reminded me of them and I couldn't help myself
