The Rat of 221b (BBC JohnxSherlockxReader)

"Joooooohn....there isn't any food." 

"Look behind you (y/n) I brought you back a muffin this morning." John replied from his chair where he was reading the paper.

"Really? Oh tha--" (y/n) cut off mid-sentence and yelled at the top of her lungs.

"(Y/N) WHAT IS IT?!" John replied having jumped out of his seat to face her. He saw that in the .2 seconds of him turning around she had managed to jump on the table, now crouching with cup in hand ready to be thrown.

"(y/n) what was it?!"

"A rat John! It was a rat!" John sighed with relief.

"That's all? A rat? You know I'm surprised at you. I didn't think you were the type of person to jump at seeing a mouse."

"I don't jump at mice, John. I never have but that....that was a new breed of vermin." John saw she still had the cup raised  and her eyes kept darting across the floor.

"What do you mean by that?"

"I mean, John, that... that was not a rat it was a Rat. As in if I hadn't been looking right at it I would have mistook it for a raccoon."

"Oh God no...." a look of worry began to spread on John's face.

"John what is it?"

"It's back." Just then Sherlock walked through the door.

"What's back John?" He asked, hanging up his coat and scarf.

"Sherlock," John replied turning to him and dead panning. "It's back." A look of horrified shock came across Sherlock's face.

"No. No no no that bastard rat, not again!"

"Would either of you mind cluing me in on this? I feel like I'm missing something here." (y/n) called from the kitchen. Sherlock walked over, finding her still in defense mode.

"Well, (y/n), John and I have ran into this creature before. It was a few weeks after we moved in. Whenever we were out we would return to find the furniture chewn, scratches in the floor, and whatever food that was left around had been eaten. I initially presumed it was a cat, given the size of the scratches and bite marks. I assumed that Mrs. Hudson had left some doors open and it had wandered in. However, upon further investigation I found hairs throughout the apartment that most definitely belonged to a rat. But, no matter how hard John and I tried to catch it we failed. Eventually it left and we didn't have to worry about it any longer. But not before it managed to damage my violin with his vile teeth," Sherlock stated scowling, "Now it appears it's the animal has made it's return, no doubt to reek more havoc." Sherlock said, all the while looking around the flat for clues on the whereabouts of the beast. 

"Awesome," (y/n) sighed, "So we basically have a rat on steroids running around the apartment."

"But we can get it this time right Sherlock? I mean we've dealt with it before so we know it's patterns of behavior." John said looking hopefully at Sherlock. 

"Possibly. Quite possibly." Sherlock said as he got down on his knees to look at something under the sofa. John followed and kneeled down to look as well.

"(y/n) do come down from there. You will be of no use cowering on the table." Sherlock said now looking at floorboards in front of the sofa.(y/n) reluctantly got down leaving her mug of death of the table. 

"I wasn't cowering. I was on lookout."

"Well, come look out over here for anything that could tell us where the thing has escaped to." 

(y/n) did as told and helped the boys look around and under the sofa for clues. After a few minutes scratch marks were found along with biscuit crumbs. Sherlock said that the scratch marks were deeper than last time, meaning that the rat had grown even larger in
size. Everyone was still knelt down when heavy padding noises were heard behind them. They all looked at each other then simultaneously got up and turned around. The sight they were greeted with was terrifying.
