Mrs Hudson had been complaining for weeks about the loud bangs and music and stamping coming from Sherlock's flat, so DI Lestrade was not altogether surprised when he arrived one day with a case for the consulting detective and managed to make it to the top of the stairs without being noticed.
The music playing was loud and fast, with a heavy beat, and the sound of it evoked images of rural taverns in Spain, with long, raven-haired beauties with tanned skin and sultry dark eyes dancing and swirling in those long dresses with the ruffles that they kept hiking up to show off their legs.
When Lestrade got to the doorway of the flat, the only thing that matched his mental vision was the raven-coloured hair. Well, that . . . and the dancing.
Sherlock had positioned a full-length mirror not-quite-sideways-on to the doorway, so he didn't see Lestrade at first. Lestrade was incredibly thankful for that, as it allowed him to gawp unabashedly for several moments. He felt like one of those cartoon characters whose eyes popped out of their heads on stalks while their mouths fell open until their lower jaws were on the floor.
The normally stand-offish consulting detective was wearing a loose red shirt that was open at the neck and was tucked into leather trousers that looked as if they'd been painted on. Lestrade idly wondered just how long it had taken Sherlock to get into them, and how long it'd take to get him out again. The black shoes on his feet looked completely normal – until something flashed at him as Sherlock lifted a foot, and Lestrade realised the bottoms had some kind of metal on them.
As Sherlock brought his foot down again in a hard stamp, Lestrade realised – with some surprise – that he was wearing tap shoes. At the same time, Sherlock brought his hands up beside one ear in a clap, and spun around.
And froze.
Lestrade grinned at his horrified friend. "Evenin'," he said. "Don't let me interrupt." He twirled a finger as if telling Sherlock to turn around. "You seemed to be doing quite well."
"I—" Sherlock began. "Ah—" He finally seemed to realise he was holding his hands up in the air beside his head, and sheepishly lowered them, before drawing himself up with as much dignity as he could manage – which wasn't a lot. "It's for a case," he said, lifting his chin so that he was looking down his nose at Lestrade.
"If you say so, sunshine," Lestrade agreed, amused. His amusement only deepened when a faint blush suddenly streaked over Sherlock's cheekbones.
"Is there a reason you're here playing voyeur, Lestrade?" Sherlock snapped, going on the defensive.
Lestrade held up the case file. "Well, I was bringing you a case," he said. "However, it appears I've come to be entertained, instead."
Muttering imprecations under his breath, Sherlock stalked across the flat to violently switch the music on his phone off, causing Lestrade's ears to ring in the abrupt silence. Then he stalked back across the flat and snatched the file from Lestrade's hands. He briefly paged through it, frowned, turned the file upside down, and then scowled at Lestrade.
"It was the exchange student from Heidelberg," he said, tossing the file back at Lestrade. "Boring!"
"Well, then," Lestrade said, stepping into the flat. "Are you going to show me your moves?" He shut the door behind him.
And the music began again.
A/N - I went to see Riverdance 21 at the weekend (brilliant show!), and it included a couple of instances of flamenco dancing. Unfortunately, I have no interest in that type of dancing, so during those, my thoughts went wandering. In the second lot, the lady dancing was wearing a black dress - and it occurred to me that the flounciness would have suited Sherlock (uh, the dramatic flounciness of it, not the actual dress lol). That led to thoughts of Sherlock actually flamenco dancing, and this was the result. And since Riverdance was the inspiration, then that's why Sherlock's wearing tap shoes for it ;)
A/N2 - My fascination for Lestrade has apparently taken over, since most every Sherlock thing I've started to write recently has turned into Sherstrade of one degree or another.
