You're in Sherlock (Sherlock × Reader)

The Empty Hearse: Chapter 8

"What? Trying to hide a hickey or something?" John noticed your awkward movements. He'd obviously been joking but little did he know, you were.

"I, uh, um... I'll let you two talk." You looked in between them, feeling like you were invading a conversation that they needed to have, just the two of them. Plus, you wanted to get yourself out of the awkward conversation.

"No way!" John yelled, grinning back at you.

You ignored him, rushing back to your bedroom. So much for the scarf, you thought, pulling it off your neck. It was too warm in the flat to be wearing it anyway. You paced the bedroom, thinking about the current case you were on. You again pictured the train cars in your mind, thinking back to how something was different in the videos. You played them over and over again before it suddenly hit you. You'd been stupid! It was practically staring at you right in the face. You hadn't seen it because it was so obvious!

"Y/n!" You heard Sherlock call just as you were getting up to race into the other room. You hurried in to see what he was on about.

"It's not an underground network. It's an Underground network." He told you with wide eyes.

"Right, so I was studying the differences between the train cars in my head when it left versus when it arrived at St James' Park and you won't believe this." You spoke quickly, walking over to Sherlock's computer. John and Sherlock followed you as you pulled up the video image of the train. "The tube has seven carriages when it leaves Westminster and when it gets back..." You played the video and Sherlock's eyes widened in realization.

"Sometimes a deception is so audacious, so outrageous that you can't see it even when it's staring you in the face." He spoke softly, looking at the screen.

"It only has six carriages at St. James." John squinted at the screen and you nodded. "But that's... I... it's-it's impossible." John stuttered in disbelief as he looked at the screen. Of course it was possible because the video held the evidence.

"Moran didn't disappear – the entire Tube compartment did. The driver must have diverted the train and then detached the last carriage." You looked to Sherlock, thinking. It didn't make sense, but that's what had to have happened. There was no other logical explanation.

"Detached it where?! You said there was nothing between those stations." John laughed in disbelief looking from you to Sherlock.

"Not on the maps, but once you eliminate all the other factors, the only thing remaining must be the truth." Sherlock spoke quickly, gesturing back towards the screen. "That carriage vanished, so it must be somewhere." You nodded in agreement.

"But why, though? Why detach it in the first place?" John spoke in confusion, you thought about the answer to his question, pondering it. Sherlock paced around the flat, his thoughts spewing from his mouth.

"It vanishes between St James's Park and Westminster. Lord Moran vanishes. You're kidnapped and nearly burned to death at a fireworks par-" He suddenly stopped and he turned to you with a look that showed you he understood. You scanned his face, slowly understanding. You thought back to something Sherlock's mom had said. A debate at parliament... "What's the date, Y/n, today's date?" You looked at him with wide eyes.

"November 5th..."

"My God." John shook his head as he too, realized what you and Sherlock were talking about.

"Lord Moran – he's a peer of the realm. Normally he'd sit in the House. Tonight there's an all-night sitting to vote on the new anti-terrorism Bill. But he won't be there. Not tonight. Not the fifth of November." Sherlock spoke as he smiled over to you and John.

"'Remember, remember.'" John quoted with a small nod.

"'Gunpowder treason and plot.'" You finished looking up at Sherlock with an intense and thoughtful look.

You immediately called up Howard, again asking if there was any way there could be a tunnel that hid in between the two stations. Howard, once again, denied it.

"There's nothing down there, I told you. No sidings, no ghost stations." Howard looked at the three of you through his computer screen with a frown. You shook your head, not taking no for an answer.

"There has to be. Check again." You told him. Howard leaned off screen, rustling through papers as he studied for more information on the tunnels to get you the information you wanted.

"Look – this whole area is a big mess of old and new stuff. Charing Cross is made up of bits of older stations like Trafalgar Square, Strand..." John spoke as he flipped through a book.

"No, it's none of those. We've accounted for those." Sherlock shook his head, flipping around the other maps that scattered the kitchen table. "St Margaret's Street, Bridge Street, Sumatra Road, Parliament Street..." He hummed as he looked over them. Howard suddenly appeared back on the screen as he looked over the three of you.

"Hang on, hang on. Sumatra Road. You mentioned Sumatra Road, Mr Holmes. There is something. I knew it rang a bell." He leaned off screen as he again flipped through papers, searching for something. "Where is it? There was a station down there." Howard spoke, leaning back into view. You looked at him, wanting to know more. This could possibly be what you were looking for.

"Well, why isn't it on the maps?" John shook his head, pushing away the maps he'd been looking at.

"'Cause it was closed before it ever opened." Howard explained, flipping through a book.

"Oh..." You hummed, eyes wide as you watched the screen. That would make perfect sense. There was a tunnel already built that was closed off to the public, this was exactly what you were looking for!

"What?" John asked.

"They built the platforms, even the staircases, but it all got tied up in legal disputes, so they never built the station on the surface." Howard held up a book that showed a map, he pointed to the spot he was talking about triumphantly. You looked to where he was pointing with wide eyes.

"Sherlock... that's..." You stuttered, looking over to Sherlock, your face creased in worry.

"Right underneath the Palace of Westminster." Sherlock finished, taking off towards the door. You followed him, and John still sat at the table not yet noticing your moments towards the door.

"And so what's down there? A bomb? Oh..." John turned to see yours and Sherlock hurried actions and he scooped up his coat, rushing with the two of you out the door.
