Sherlock Holmes, the World's Only Consulting Detective, prowled in the darkness of the alley, eyes narrowed as he searched for any sign of the illegal trade of high government security weapons. It was strange, the alley was silent and clean, too clean for and alley being left alone but there was no evidence to prove anyone had been there in the first place. The tail of his coat brushed the ground as he slid behind a trashcan as figures moved in the darkness, they stepped into the light, completely unaware of the detective's presence.

"Can you believe the boss is still alive?" The taller asked as he walked into the alley, a small bag hefted over his shoulder as he talked to the shorter man "Shooting himself in the face like that after making Holmes jump off a building! Impossible but I'm not arguing the man is a genius."

The shorter growled as he walked by Sherlock's hiding place "Holmes survived too. Boss says we aren't allowed to kill him until the next stage that's activated and that sucks."

"We'll get our chance," the taller laughed, dark auburn eyes shifting straight to Sherlock's hiding place, the Detective bit back a gasp of horror when he realized they knew he was there "eventually. Moriarty said he wanted us to bring him in...no matter what cost."

"And look!" the shorter laughed, pulling a gun from the holster at his waist and aiming directly at the detective "Here he is! Without us having to drag him away from his flat. Just great, why don't you stand up Mr. Holmes? You don't want to get your coat dirty."

Sherlock stood, eyes narrowed coldly as a bullet clicked into the gun poised at his head "Oh look, Moriarty's boys caught me! What an unexpected surprise! Never thought anyone dumber than Anderson could get me."

"Be quiet Mr. Holmes." the taller snapped, patience wearing thin with the genius as he aimed his own gun at the detective "We'll kill you nicely or we can take you to Moriarty. He's been dying for round two!"

Sherlock smiled, he bent his neck down so that his eyes were hidden so the two wouldn't see their wolf-like yellow glow. He growled, a feral sound that tore through the alley causing the two to jump in fear and surprise that a sound like that could resonate from a human throat. Sherlock looked up, a smile on his pale features and when the shorter saw his yellow eyes he screamed in horror but the taller man quickly placed a hand over his mouth.

"Killing me?" Sherlock asked with a shake of his head as he walked forward, the two were too transfixed with horror to move "You aren't that ambitious...besides only two will die tonight and they'll be you. It truly has been awhile since I've transformed let alone killed. Well tonight it's different."

Sounds of grinding, snapping, and worse echoed into the night as he shifted. His clothes seemed to disappear as if mist as he transformed and instead of black cloth, jet-black fur raced across his new Lupine form. It was the Taller man's turn to scream in horror when he saw two feathered wings sprout from the wolf's back and the two jumped back in horror when the transformation was complete. A snarl tore through the air as Sherlock stepped into the light.

Instead of being the regular size of a wolf he was much larger. At least six feet tall on all fours while long feathered wings folded at his back, florescent blue decorate the end of his wing feathers and it glowed in the darkness. Screams of terror were heard as Sherlock lunged, teeth bared, any sign of being human was gone while the beast took over completely. Blood tainted the air as claw and teeth met throat. Screams cut short as the beast stood away, eyes narrowed with blood sticking its black fur back. It walked away from the warm corpses leaving only bloody paw prints as it melted into shadow, completely lost as it made its way back to his flat on Baker Street.

He never noticed the figure of Moriarty watching from the rooftops, a smirk on his face as he whispered "This is going to get interesting."

"You're brother is not normal is he?" John growled at Mycroft, who sipped his tea, eyes widening for a quick second before he set down the cup "Don't lie to me. I've seen the way he acts, there is no way he's human. Don't even play with me Mycroft or I swear."

The elder Holmes sighed as he looked at the fire, few actually knew the truth of what his brother was, the certain few were his father,dead, suicide, their mother, still alive and living well in the country, and finally him. Mycroft had every reason to fear what Sherlock was being he couldn't control the beast, not at all.

"You're right." Mycroft said sadly, a thorn of guilt pricking his heart as he spoke the words "Sherlock isn't fully human. He is Avian Lupine Hybrid. A very rare creature...a monster more like it. Uncontrollable and completely animal, no mercy in its veins at all."

John raised an eyebrow, confusion taking hold but he quickly shook it off as he forced himself to believe 'The British Government', "How did he get this way? Was it an accident or was he born like that?"

Mycroft blinked, eyes reflecting the fire as he sighed "We were really low on money growing up and Sherlock had a special blood type, only seen a few times and the only kind that had not been tested with the experiments going on during that time. The government came around and said they'd pay our family millions if they could test it out on Sherlock. Naturally our parents said no but Sherlock knew the place we were in and volunteered to go...and that was the biggest mistake I ever made."

"Why?"

"Because I talked him into it." Mycroft said sadly, memories of a young Sherlock swallowing any fear he had to help his family for something that would almost kill him, he pushed them away to finish the story he was telling. "We wouldn't see him for months and the next time we saw him...it was like looking at a completely new child. He had been born with bright blonde hair, hence the name 'Sherlock', and brown eyes but when we saw him he looked like a younger version of himself now."

John looked up, he didn't realize that his hands were grasping the arms of the chair until his knuckles turned white, he loosened his grip before saying "What had happened at the facility?"

"They just didn't bring him to our front door John," Mycroft said, a guilty look crossing his features as he continued on "the government scientists who had worked on the project had invited us to look at the progress. We went to see him but when we got there, something had happened while the head lab research agent had fetched us. Everyone in the entire facility was dead, torn apart and were either dead or bleeding out on the floor. We walked through trying to find Sherlock and when we did he was still in that 'wolf' form, cowering away when he saw Mummy's terrified face."

"Oh my god." John breathed in horror, Sherlock investigated death, but cause it? Never.

Mycroft swallowed sourly and he spat out the next sentence "Sherlock was never the same again...and we never treated him the same. I was always careful and snappy, calling him 'Wolf boy' and everything else. My father, shot himself in the face right in front of Sherlock, saying it was all his fault. Mummy was the kindest, she accepted him and he was always the most protective over her. It was terrible, he tried to commit suicide many times, but the advance healing took over completely."

"Can he even control that thing?" The Ex-Army Doctor said, eyes flashing to the picture of Mycroft and Sherlock on the stand.

"No." Mycroft said "If anything, that thing controls him."

"So I am living with some murderous winged wolf? Great, my day just got a lot better." John growled sourly.

John stood up, slipping his coat on as he walked out, leaving Mycroft alone to his thoughts until he heard the elder Holmes call after him "Be with him John! Make sure he doesn't let it take over!"
