A/N: For Uchiha B. Not feeling inspirational about The 'K' Mystery so this will have to do for now. She's been wanting some IY/Sherlock that isn't hers lol.

There it was again – the familiar chime of his phone that alerted one of another text. It was odd, really, that she could acquire his number when it was clearly unknown. Even to John. Well, he had it now but even then he constantly changed his number for really specific, mysterious, reasons.

'How is it that you've managed to avoid me time and time again? I've tried hacking into your mobile but what deludes me is the block I just can't seem to get past. Who's hiding you?

His leveled eyes narrowed into slits when his screen suddenly blacked out for a moment before his main page popped up again. Then that familiar chime went off and a light began flashing at the corner of his cell. Sherlock pulled the message up immediately, his lips thinned into a firm line as his blue eyes roved over the text greedily.

'Curious, are we? :P

Never thought I'd see the day when even Sherlock Holmes can't figure out a simple riddle. Would you like to try again?

"Infuriating woman. Giving me one-letter riddles."

John rose a brow at his flatmates sudden outburst, dark eyes glancing up at the detective's annoyed expression he now sported upon his passive face. His brows were slightly contorted in anger and he seemed to have slammed his phone shut if the death-grip he had on it was anything to go by. Honestly, you'd think he'd have broken it by now.

There was never a dull moment when you were Sherlock's friend. Considering I'm his only friend, that is.

He sighed, heavily, before shutting his book softly and placing it down on the desk next to him. "Sherlock, what is it now? Irene?"

Bloody hell, if he had to suffer through that mess again he'd honestly think he'd kill himself. Well...not really. But Sherlock didn't associate with those of the opposite sex – let alone acknowledge their presence.

And he wouldn't just mutter, 'Infuriating woman' for purposes sake.

Sherlock's sky orbs turned a sharp eye his way, his brows relaxing suddenly before he soon began to pace the flat anxiously, annoyingly, really. It was as if someone took his toy and now he was plotting ways of trying to get it back.

But from whom? I might never know. And I don't think I really want to know in the first place.

John merely shook his head in exasperation when Sherlock's long, nimble fingers were suddenly flying across his touch screen in rapid motion. He'd honestly pray for the woman that had managed to catch his flatmates attention.

'You can't hide forever. Eventually, you'll slip up. It's a human's natural instinct. I'll solve you, Miss Taisho.
