I'm onto it. -SH
Sherlock paid the taxi driver and got out, pulling his coat collar up further against the bitter wind as he watched the cab lights fade into the distance and he was left in the darkness, his eyes focused on the small light from the farmhouse. He vaulted over a hedge and into the field, trampling through the grass. He approached the building from behind, hoping to remain out of sight to whoever was residing inside. As he got closer he ducked down and made his way towards the door on all fours, clinging to the side of the walls. He could hear movement inside that confirmed his suspicions.
Sherlock paused slightly upon reaching the front door, then took a deep breath and shouldered it open, falling onto the hay covered floor and nearly knocking over the man holed up inside, who was just unpacking a rather large sniper rifle. The man was considerably surprised by Sherlock's attack, surprised enough to not react immediately and Sherlock was able to throw a punch to his right cheek. He flew backwards into the wall, then regained his senses and adopted a fighting stance similar to Sherlock's. For a moment they circled each other like opponents in a boxing ring, then the man launched himself and laid his hands round Sherlock's neck. Sherlock kicked him in the kneecap and he fell to the floor and Sherlock quickly repositioned himself behind the man with his arm locked tight around his neck. The man's hand reached out for a hand gun that was just within his grasp. The snapping of the assasin's neck and the shot from the hand gun were almost instantaneous.
Sherlock staggered back, his hand instantly going up to the wound. The bullet had hit the lower part of his neck, somewhere near his collar bone. It was bleeding profusely and rather painful. He bent over the dead assasin and picked up his gun, just in case he should come across anyone else, then headed to the door. Mycroft's mansion was in the distance, its lights bright and welcoming. He hadn't planned on making an appearance there tonight, but it was a damned sight closer than the nearest hospital and besides, John would be there. And John was a doctor. Surely he'd remember how to remove a bullet and stitch up a wound. Sherlock set off, staggering through the fields, leaving a trail of blood behind him and growing weaker by the minute. He didn't mind too much though. He'd done his job, and that was all that mattered.
