You're in Sherlock (Sherlock × Reader)

The Hounds of Baskerville: The End

"Oh my God." Lestraude stumbled backwards and you paced beginning to panic. You caught movement in the corner of your eye and you saw a figure looming towards you. A breathing mask covering their face. You rushed towards them, yanking the mask of their face to reveal who it was. When you saw their face, you pushed them away in agony, screaming as you stumbled away.

"No!" You yelled, falling onto the ground. You clutched your side in pain as you took deep breaths, your mind not focusing. You covered your mouth to prevent yourself from vomiting. You felt sick.

"It's not you! You're not here!" You heard Sherlock yelling. You heard a struggle behind you then felt someone grabbing your shoulders, helping you to your feet.

"Y/n, look." Sherlock told you, pulling you towards Moriarty.

"No!" You screamed in combat, struggling in his grip as he pulled you towards him.

"Look!" He demanded, pushing you towards him. You fell on your hands and knees and saw Bob Frankland groaning in pain a few meters in front of you. You blinked at him, breathing in relief that it wasn't who you thought it was. Then it all started to make sense as you looked to where you'd thrown Frankland's gas mask to the side.

"The fog." You told Sherlock, pointing to the mask. "The fog!" You announced to everyone, understanding where your fear had jumped up from.

"What?" John asked, his torch still aimed on the hound.

"It's the fog! The drug: it's in the fog! Aerosol dispersal – that's what it said in those records. Project HOUND – it's the fog! A chemical minefield!" Sherlock understood as he looked at the fog that had been all around you this entire time. You'd all been breathing it in without even knowing!

"For God's sake, kill it! Kill it!" Frankland yelled, pointing towards the hound as he stood up from his spot on the ground. You looked over to see the hound quickly approaching.

Lestrade and John both began shooting at the hound, until eventually a bullet hit it, sending it to the ground. It whimpered before it became limp. You watched it, but saw no signs of movement. Sherlock rushed over to Henry, pulling him to look at the hound.

"Look at it, Henry." Sherlock told him, much like he had with you to show you that Frankland wasn't truly Moriarty.

"No, no, no!" Henry protested, but Sherlock was determined. Henry eventually complied. Looking down at the hound in the light of Sherlock's torch. He realized it was in fact, a regular dog. He turned towards Dr. Frankland, anger taking over his emotions.

"It's just ... You bastard. You bastard!" Henry screamed as he threw himself at Dr. Frankland, a scream of rage bellowing from his throat. He tackled him to the ground, screaming. You quickly ran towards him, carefully wrapping your sore hands around his shoulders as you attempted to pull Henry away. Sherlock, John, and Lestrade came to your aid, pulling on the man as he screamed in Dr. Frankland's face. "Twenty years! Twenty years of my life making no sense! Why didn't you just kill me?!" You all managed to pull him off and John and Lestrade restrained him as he cried.

"Because dead men get listened to. He needed to do more than kill you." You told Henry, shaking your head at Dr. Frankland in disgust.

"He had to discredit every word you ever said about your father, and he had the means right at his feet – a chemical minefield; pressure pads in the ground dosing you up every time that you came back here." Sherlock grinned, spreading his arms out as he spun, looking around he Hollow. "Murder weapon and scene of the crime all at once. Oh, this case, Henry! Thank you. It's been brilliant." Sherlock laughed. You crossed your arms, not able to focus on the case at the moment, otherwise you'd be laughing along with Sherlock.
