As soon as Sherlock reappeared from his room, John hastily grabbed his coat, and the two took off. The tall detective was several paces ahead of John, keeping a steady gait, but the short doctor had to jog to catch up.
"Where are we going, then?"
"You'll see," Sherlock said in a tone that almost sounded playful, though his face did not change in the slightest. They took a few turns, and after about ten minutes, eventually arrived in a shabby alley that John did not recognize.. John noticed faded vandalism on the wet brick walls on either side of them. He hadn't noticed until now, but there was a light drizzle of rain.
"Sherlock," John began, but his companion cut him off before he could continue.
"Not now, John." Then, in a lower voice, "We're almost there." At this moment, John glanced to their right and saw deserted cans next to small patches of dry ground where someone had been sitting not long ago. Half distracted, John heard Sherlock muttering quickly under his breath, which the former could not make out entirely.
They turned yet another corner and Sherlock held out his arm, signing to Watson to stop.
"Wait for me here. Don't move." Sherlock's voice was but a whisper, so quiet that John almost didn't hear him over the increasing rain. His friend continued toward the end of the alley when he suddenly disappeared into an unseen part of the back street.
John stood there, on guard, waiting for what felt like almost half an hour. The rain had picked up, now heavier than before. He looked up at the sky, which had become dark and cloudy, though it was barely noon. He checked his phone. While taking a few careful glances around, John wondered if he should text Sherlock to see what was taking him, but then he noticed a tall dark figure where Sherlock had gone. It could only be him, John reasoned.
"What took you so long? It's been nearly an hour – " John stopped when he heard a weak voice,
"John. Help."
With that, Sherlock collapsed onto the muddy ground.
"Sherlock!"
John rushed forward and immediately helped the fallen man to his feet, careful to not let him slip.
Review, please. Short, I know, but I promise I'll write more soon.
