"Sherlock, this is ridiculous."
"It's practical."
"Where did you even find adult-sized heelies?"
Sherlock waved his hand. "The internet is a wondrous place, John."
John jogged to keep up with the speeding detective. "Where are we even going?"
"Lestrade called me. There's been a murder."
"So we're heading to…"
"Scotland Yard."
"But that's 2 miles away!"
"Yes."
John sighed and kept quiet. Better to save his breath for all the running he would have to do in the future.
They didn't take many taxi rides after that.
While John kept telling Sherlock that he was gonna get hurt or run into something. So Sherlock didn't tell John about his one incident involving his new footwear.
He had decided to be generous, and went himself to get milk. As he wheeled down the aisles to the cash, he went through the movie aisle. He sped right in front of an old lady and crashed into the £3 DVD bin.
As the old lady huffed and glared at the detective, he picked himself up.
The only words the lady heard was an apology - to the bin - and a muttering as he rolled away: "Use the aisle, Sherlock."
