I am so sorry for taking so long with this chapter, forgive me! I swear I will try and get the next one done in a decent amount of time haha, but in the mean time enjoy! :)

"There's been another murder."

Castiel's gravelly voice suddenly filled the room, making Sam and Dean jump before they quickly turned to face him.

"For God's sake Cas we spoke about the whole appearing thing!" Castiel merely glared at Dean, furrowing his brow.

"But it is the most efficient way of communication." Dean simply sighed loudly, there was no talking to the angel sometimes and it had the potential to drive him up the wall. There was silence for a few moments before Sam rolled his eyes; he swore they could be so childish at times,

"Tell us about the murder then Cas. When did it happen?"

"It was just this morning, every bone in the body was broken and there was a note though I believe it was meant for Sherlock Holmes." Sam sat up at attention; it certainly sounded like the work of a demon but there was no way Sherlock could be involved with something like that,
"It seems pretty obvious that the man he is after must be working with Crowley. Or demons at least." He turned to Dean and prepared his puppy eyes just in case Dean tried to say no,

"We should work with them."

"What no! They know nothing about hunting and they would not be able to help." Dean already held some form of dislike for Sherlock, he could feel that something was not quite right with him… it had absolutely nothing to do with getting called a compulsive liar with just one glance.
Cas moved forward and stood directly in front of Dean, 'uncomfortably' close.

"They can help us Dean. They seem smart enough they can learn." Dean groaned as if this was possibly the worst thing he was about to do,

"Fine."

"What how is it that you listen to an angel in a trench coat and not your own brother!" Sam let a over dramatic look of shock cross his face, of course he knew the reason he just wasn't too sure Dean knew himself…

"Any way, now the angel has briefly talked you 'round I suppose we better head back to…" He quickly searched his pockets for the few notes he had been forward thinking enough to write down,
"221b Baker Street?" He raised an eyebrow at Dean and before he could even reach for his coat Cas was gone, he was secretly glad that he didn't teleport them or whatever it was. It was not the most pleasant of experiences to say the least.

They both grabbed their jackets and tucked their respective guns into the back of their waistbands… well you could never be too sure. Dean looked around the room as if he were searching for something then remembered that he didn't have his baby with him.

"I suppose we better get a cab?"

As they stood on the step of 221b Dean was practically thrumming with frustration,

"What the hell was that! The traffic was awful and that cab driver was crazy! I would rather fight a demon than deal with that again. God, even Cas zapping us about is better than that!" Sam shot Dean an amused look,

"Quite finished?" He turned back to the door and knocked loudly, they waited a few moments and just as Dean was about to say something they heard muffled shouting coming from inside.

"Sherlock for God's sake just once I would like you to get off your arse and answer the door!" The sound of footsteps could finally be heard coming down the steps but before the door was opened they heard a shout again,
"And will you please put some bloody clothes on!" It took more than a lot of effort for Sam and Dean not to start laughing as John opened the door looking slightly exasperated. As soon as he saw the brothers though a smile made its way onto his face and he invited them in,

"Just head straight up and hope he is wearing clothes." An incredulous look passed over Dean's face,
"Is it usually like this?"

"Oh you have no idea but you get used to it." John chuckled slightly as they walked up the stairs and into the flat and as they entered Dean stopped in his tracks.

"Oh man, come on! Put some clothes on." Sam and John started laughing as Dean turned away over dramatically from where Sherlock was sitting clad only in a sheet that was precariously balanced on his waist.

"Why? When clearly you are the only one who is uncomfortable." Sam and John were now both nearly gasping for breath through their loud laughs, looking back it really shouldn't have been that funny but then it was just infectious.
Sherlock continued to stare at Dean, almost glaring but a fleeting expression of shock quickly took over his features. He managed to school them into a more neutral expression in mere moments but Dean had still noticed the change and he turned to see what the detective was now staring at.

He really shouldn't have been surprised when he saw Castiel standing behind him, awfully close behind him and he nearly startled back. Cas for once ignored Dean and examined Sherlock under a scrutinising gaze,

"Is that a new way of dressing on earth now? It seems rather similar to a style that was in 'fashion' approximately 2000 years ago." Dean immediately shook his head quickly, shaking his hands along with it for added emphasis,

"No! No, you probably shouldn't start dressing like that… when you're here." Sherlock keenly observed the way Dean turned away from Cas for a moment, as if he needed to reign himself in and Sherlock could see why. It was so glaringly obvious the effect this Castiel had on him he didn't even feel justified in pointing it out, honestly to not see that you would have to be more of an idiot than Anderson.
Dean cleared his throat before turning back to the 'angel',

"So what did you come here for Cas?" Sam and John had finally managed to calm down and were now leaning on each other, Sam's arms round John's shoulder because they were very nearly close to falling on the floor with laughter.
The silence before Castiel could reply was only broken by the occasional stifled giggle coming from Sam or John and Sherlock rolled his eyes.

"It's about the murder, there was evidence of-" Sherlock cut Castiel off before he could even consider finishing his sentence and simply picked it up where he left off,

"Sulphur. There was sulphur at the crime scene and that's why you're here." John stood up a little straighter, the information finally getting him to stop laughing completely, curiosity taking over instead.

"Like the others?"

"Exactly like the others John, I just couldn't find the connection…"

"He was absolutely intolerable." Sherlock simply ignored John's comment and turned back to Dean,

"Though since the sulphur obviously means something to you I'm sure you can explain." Sam realised he was still leaning on John, his arm wrapped around the smaller man's shoulders. He promptly moved it, chewing his lips slightly before he realised he was going to have to inform Sherlock and John,

"Well, the sulphur is a basic sign of demonic possession." Sherlock remained decidedly unperturbed this time, choosing to simply go along with them. After all how often had he said once you have eliminated the impossible, whatever remains, however improbable, must be the truth.
The truth just so happened in this case to be pointing toward demonic possession…

"It would at least explain the unusual causes of death, particularly the broken bones with no indicative trauma." Dean nodded in agreement,

"That is also why we are here. The head honcho is apparently here and working with your Moriarty." John determinedly stepped forward as he spoke to Sherlock,

"Right Sherlock put some clothes on, I will call Lestrade. If we all go and check out the body we might find something since we can combine what we know. At least it will give us more of a chance to find out what they are doing."
Sam stood and couldn't help but be impressed by the unassuming John Watson, he had only recently found that that angels and demons weren't a thing of fantasy novels yet he was still calmly stepping forward and taking charge.

At the prospect of a fresh crime scene and a chance to acquire new knowledge, not just pertaining to the case, Sherlock nearly jumped up to get ready, barely gripping the sheet enough to keep himself covered as he went to his room.
As Sherlock went to get ready Castiel's voice filled the silence again,

"I will continue my search for Crowley and this Moriarty." Dean quickly got in a comment before Cas disappeared leaving the three of them waiting on Sherlock,

"Don't appear like that at the crime scene, people… y'know?!" John couldn't help but shake his head in disbelief at the events currently transpiring as he searched for Lestrade's number in his phone.
The phone call was brief and to the point, just informing him that they were on their way over now to have a look at the scene. Once he had hung up he heard Sherlock's bedroom door opening and he spoke to the brothers, though admittedly he was mostly facing, and talking to Sam…

"Well then, shall we?"
