John's grin slowly faded away to a look of sheer confusion.
"Sherlock?" He slowly started to track his way around the edge of the living room, weaving through the piles of books dotting the floor without taking his eyes off the figure in front of him.
Sherlock smiled, his eyes gleaming with the joy of the chase.
This chase was new.
Different.
"What is it, John? A new case for me?"
He stretched backwards on the sofa; the sunlight streaming through the window caught the beads of water trailing from his hairline, making them shine like nothing John had seen before.
"Not a case, just an observation."
"Only an observation? DEDUCE, MAN!"
Sherlock sprung from his seat and flung the handtowel that was wrapped across his waist into the adjoining room.
"Look at the situation," he grinned "what does it mean?"
John took an awkward step forward, standing face to face with the great detective.
"There is no sign of a struggle"
"Correct."
"And no damage to any person nor item on this property"
"Not physically, anyway. Continue."
"Yet I arrive home..."
John was squirming now. Sherlock was going to make him say it.
He must know what this was doing.
"And what did you find, at home?"
No-one was this sociopathic.
"You were damp. And shortly after, naked."
Sherlock grinned, deviously.
"And what does this mean?"
"You want... me?"
Watson could tell he'd said something right as Holmes leant in closer and whispered to him with such excitement his voice sounded nearly as ready as... parts of Watson.
"Perfectly sound analysis..."
John felt Sherlock's thumb slide into his waistband.
"But I was hoping you'd go deeper."
