Chapter 2 - Noticed Impossibilities

A/N(2014)- This is set just after series two and the Christmas special with Donna, she said "Find someone." And after series three of Sherlock after The Empty Hearse. I know London very well and I do enjoy the excuse for wandering around to get journeys for this story.

(2017) I had uni for three years, now in the last month or two, between work and social, I have had the most fun writing chapters 2-16 for my enjoyment, and I guess yours too, hehe.


The incident with this so-called Doctor had put Sherlock in a vile mood, he had walked around London for half of the night on autopilot thinking through what he had seen, making passers-by jump at his seeming random outbursts of "Impossible!" "Ridiculous!"

No matter how many times he ran through various explanations for his findings, he found himself always returning to the facts, facts he couldn't… or wouldn't believe. He had been going around in circles for hours, and by the end of the night he found himself no closer to a logically appropriate explanation. But he had seen it though, the man himself was seemingly impossible or at least highly improbable, but a binary cardiovascular system, he'd seen two separate sets of pulses throbbing in the man's neck as his heart(s) rate had risen? How can a man have two hearts, there would be a ludicrous amount of medical complications, besides there would have been reports of such an unusual phenomenon. And those eyes, nothing different about them physically, but that look, like he'd seen so much despite being no more than 36. That expression of loss etched into them, an old soldiers gaze.

Sherlock found himself in Witcomb Street, a mere two-minute walk to Trafalgar square and five minutes from the river and the Hungford Bridge. The Thames had been slowly refilling itself from the North Sea after it had been almost fully drained at Christmas. He had no new information on that, after he had tried to investigate the incident and nearly gotten himself shot by an unusual man in a genuine blue 1940s trench coat. He made it to the edge of the Thames and sat under the footpath bridge on the wall in front of the bright blue walkway down to the dock.

Sherlock took out the fob watch from his coat pocket, folding it over and over in his hand absent-mindedly.

"Sherlock?" he turned as he heard his name, recognising an exhausted Gavin Lestrade walking towards him up the path. He nodded in recognition before turning back to look over the river.

"Finished with the floating banker case yet?" Sherlock asked as Lestrade came to lean on the wall next to him.

"Yeah, press had a field day, apparently someone tipped off some horror channel from the TV and they made a big deal out of it all last night, I tried explaining about the flooding moving the body but it "Sounds like a stupid cover up" coming from me apparently. I've spent the last three hours just trying to get the camera crew out of my crime scene." He recounted with sighs and yawns. Sherlock smiled a little in amusement but said nothing.

"Nice watch." Said Lestrade indicating the fob watch in his now still palm, he sighed in frustration.

"Bloody thing," Sherlock cursed looking down at the watch too, "It tells me it knows all the secrets and yet all I find is more questions." he slipped the watch back in his pocket.

"Is it for a case?"

"Sort of." He mused, "Have you even heard of anyone having two hearts?"

Lestrade laughed wearily, "No. That can't be possible, there isn't really space for anything else in there, besides why would you need two? One does well enough for us humans."

Humans? An interesting proposal, perhaps this Doctor isn't human. No, that's stupid.

"How about a Police Box? Seen any of those around?"

"Can't say I have, not working ones anyway..." Lestrade replied, but then he seemed to think about it "Although there is this guy, Andrew Aiden from crime scene clean-up who swears blind he saw one disappear a few months ago, he's obsessed now, got drawings and diagrams he tries to hide in his office."

"Disappeared?"

"Yeah, he said it just sort of faded from existence, one moment it was there the next it had gone. Crazy right? Although you could probably think up some explanation that makes perfect sense." Lestrade chuckled, "Anyway," he said pushing himself off the wall and turning to face Sherlock. "I know I'll crash onto the sofa as soon as I make it back so I should probably get home and sleep. See you Sherlock." He patted Sherlock's shoulder and left him to his thoughts.

Was he ever going to get any answers or just more questions? If it was a case he would be delighted, but this somehow seemed more personal than it should be. Sherlock made it back to Baker Street at around 06:00, John had just woken and was making tea. He went immediately to the sofa and slumped down upon it.

"Tea?" John asked from the kitchen. Sherlock made a non-committal noise "You didn't find a case then?" but he ignored the question, posing his own instead.

"You're a doctor John, is it possible to have two hearts?" John had a thoughtful expression on as he exited the kitchen with two mugs, placing one in front of Sherlock and taking the other to his arm chair.

"Well yes and no, conjoined twins can have two hearts but that's not in the same body, some cases of cardiomyopathy people can have a piggy back heart that is sewn into the valves to help a weaker heart, but as far as I know there is no recorded cases of one person being born with two hearts, no." Sherlock huffed at the answer, "But an octopus has three, personally I think that's just greedy, but I get the feeling you were just talking about humans."

Another huff of irritation. Humans yes that word again like there was any other option, Sherlock's mind wanted to spin with possibilities of extra-terrestrial life; given the immense size of the universe he supposed it could be entirely possible. The media had always depicted them as odd green large headed creatures, but was it possible that there could be other, more human looking alternatives? Sherlock sighed and closed his eyes. From this point onward there was two potential paths he could tread, One- Leave the mystery alone, throw away the watch and forget the "Doctor" … not preferable but it would avoid the dragging up of things that should potentially be left undisturbed. Two- Find out everything he could, about the watch, about the "Doctor", perhaps talk to this Andrew Aiden from the crime scene cleaning team. Although the latter was much more exciting, and as it would certainly relive his boredom for at least a week, there was a stone of dread sitting in his stomach that warned him of the danger that would ruin everything.
