Okay, Black Butler, Sherlock Holmes crossover commence! :D Honestly there should be more out here because of the time and culture similarity, but ah well.

Sherlock-verse is a mix of the 2009 movie and the books, Kuro-verse...well...it's anime (and some manga for reference) and before the crazy crud of Angela/Ashe but after they get Pluto.

hope you guys enjoy!

Disclaimer: I own neither Kuroshitsuji nor Sherlock Holmes!

Prologue

The sun set upon the streets of London, creating the mood of flaming colors as if the city had been set ablaze. The light brought upon shadows to the buildings, causing young children to sidestep in hesitance to the late hour. But carriages rode on despite the shadows and fiery hues and people rushing about, and life continued to bustle in the grand English city late in the evening.

Nestled up in his coop at 221 Baker Street, the great detective Sherlock Holmes sat, perplexed on an important case at hand, not giving a care to the outside world. The file which lay upon his table was mussed and the papers were strewn throughout the room.

"Mr. Holmes," Mrs. Hudson, the landlady, interrupted, shooing the calculations away from Holmes's mind. "If you would be so kind to tidy up your mess, we have a guest apparently here for you. I will send him up and be back shortly with tea."

"Of course, nanny," he replied with a bitter twinge after her. The detective stood from his position and brushed off his dirtied trousers. How long had it been since Watson visited last that he had a guest, or even a client? Not even the incompetent Scotland Yard with help on an ongoing case. In no more than a few moments after Mrs. Hudson left, Holmes heard a knock on the door. "Come in."

Entering through the door was none other than Clarky, a constable that Holmes had grown somewhat attached to during the case with Lord Blackwood.

"Mr. Holmes, please, I have something for you that you might be interested in!" the man shouted. Holmes gave a polite smile, and nodded as he led the constable to a seat.

"Let's see, shall we?"

The constable handed Sherlock the large envelope of papers, all seeming to be assorted together.

"These are files from a case given to us a little while back, sir," Clarky explained as Holmes sifted through them. "But the case was shut down. I asked Inspector Lestrade and he said that it was confidential and none of my business. But it hadn't been touched in years, sir! And some of the papers were destroyed. What's there is all I could gather." Holmes listened patiently, taking in all that the constable was telling him.

"So then, this case is so secret, even Scotland Yard can't handle it, hm?"

"Yes, sir."

"And I take it your superiors haven't the faintest clue that you have done this," Holmes said, crossing his hands in front of his face.

"No, Mr. Holmes," Clarky replied quietly. Sherlock gave a quaint grin.

"Aha! Well then, this proves to be interesting! Don't you worry Clarky, I will make sure no one knows of your involvement in this," the detective promised, standing up and walking over to his desk of papers. The distressed constable gave a relieved sigh.

"Greatest thanks, sir. Now I have to be getting back, or else I'll seem suspicious." Holmes nodded.

"Of course. Good evening then Clarky. I will do my absolute best to solve this secret case of the Yard's," Holmes said as Clarky left. Holmes looked more in-depth through the papers and his eyes widened slightly while reading. "Well, it seems like I will be calling upon the good doctor to assist me once again," he mused.

The detective quickly grabbed his pen and a sheet of paper and scrawled a message. Just as hastily, he sealed the letter and then gave it to Mrs. Hudson to send.

John H. Watson was surprised the next morning when he received the letter addressed to him. Knowing his friend, it must have been important enough to send in the night. With a sigh, he took the letter from Mary and opened it.

Watson,

At most convenience to you, come to Baker Street at once. I am in need of your assistance once again.

-SH

Watson gave a small smile. Of course he would go immediately. It had been some time since he'd worked on a case with Holmes, and the doctor was sorely missing the adrenaline of adventure and mystery that working with his friend provided. Watson kissed his wife goodbye, grabbed his coat and shoes, and then called a carriage to Baker Street.

Upon arriving at his former residence, Watson took a breath before walking inside to meet Holmes in his room. The detective grinned upon sight of the doctor.

"Thank you so very much for coming on such short notice," he greeted jovially. "I find it that it makes a considerable difference to have someone with me on whom I can thoroughly rely." Watson nodded.

"So what exactly have you found yourself in this time, Holmes?" he asked with a smirk. The detective beckoned Watson over to his desk where he took out the envelope of papers and handed it out for Watson.

"This," Sherlock stated plainly. Watson took the envelope and took out the papers from inside. He gasped upon reading.

"The death of Lord Vincent Phantomhive and his wife, Lady Rachel!" Watson exclaimed, looking back up to his friend. "Holmes, where on Earth did you find these files?" Said detective chuckled darkly.

"I have my sources, old boy. The important thing is that this may be the most difficult case yet," he warned. "These are all that remain of any documents on the couple and the happenings of the days leading up to and on their death."

"It says here that they died on December the fourteenth….on their son Ciel's birthday…" Watson read, a frown growing on his face. "How awful, the poor boy…"

"Their son, Ciel, is still alive and has residence not far outside the city. He may be our strongest lead as to what happened and where to look next," Holmes interjected, putting on his coat. "Well then, chap; shall we pay the young Earl a visit?"

And so that's that for the prologue! Ciel and Sebby in the next chapter! Read and review pleasssseeeeE!
