"We'll take a cab and be right behind you." Sherlock barely looked at Lestrade as the officer walked towards his vehicle. "Right John, we need to make sure we've missed nothing, because once Lestrade's forensic team meander all over this place there'll be nothing of note left to see."
John looked up at his friend.
"They're that bad?"
Sherlock shrugged and paced once more back to the other sewer cover.
With a grin John started to look around him, taking note of everything that looked like it might be out of place, but in truth once Sherlock had picked up the hair he had been looking in vain for more evidence.
"Nothing?"
John jumped as Sherlock materialised beside him.
"If I'm honest, I really don't know what I'm looking for." He admitted.
Sherlock smirked.
"Well at least you admit it, now if only the police were so honest…." His voice trailed off as he took a last glance around. "No, I believe we're done here, come John, time to find the rest of the hidden clues."
As he strode away John had to almost run to keep up with him, and by the time he reached the taxi stand he was puffing slightly.
Sherlock was already in the vehicle, and as John fell in beside him he grinned and sat back.
