This is a tiny little drabble from a challenge I did on tumblr. The challenge was pretty much 'Tell me a pairing and I'll write a Valentine's fic for it'. I got Moriarty/Sherlock and then this happened.
I wasn't going to post it, because this'd be my first fic posted for the Sherlock fandom and um CHARACTER DEATH AHEAD (sorry), but I was lovingly bullied into it.
So, here it is.
John wasn't home when Sherlock returned from informing the entirety of Scotland Yard, especially Anderson, of how stupid they all were. It was unlikely that he was at the practice, as John hadn't worn his black shoes, and he'd been gone for far too long to be simply collecting milk or food or some other unnecessary item.
Before Sherlock could walk back down the stairs to ask Mrs Hudson, he noticed a disruption in the dust. This disruption led his gaze to the desk. Sherlock walked over and opened the offending drawer. Inside was a box, clearly obtained from Harrod's. It was purple and covered in pink shapes commonly called 'love hearts' despite looking nothing at all like a heart. The box didn't contain anything deadly and the hand-written note said, 'To Sherlock xx'.
Moriarty, Sherlock immediately realised. He opened it. Inside, boringly enough, was a human heart. If this was Moriarty's attempt at intimidating him…
Sherlock's phone went off. He set the box down and picked it up to read:
'Do you like my present?'
'Boring', he replied.
The phone chimed again. 'Pity. I thought I got you exactly what you wanted; the doctor's heart.'
Sherlock stopped breathing.
'Since you're done with the ordinary people, come be mine xx'
The phone chimed one more time.
'Happy Valentine's Day, honey.'
