Authors Note: THIS IS NOT SLASH. This is my second ever crossover. It is a Sherlock/Harry Potter (POST HOGWARTS). Set in about 2019. The next generation of wizards are all about improving muggle relations and getting on with everyone. A Liberal movement has caused the stirrings however of the far right political movements across Europe once more and Harry is being placed undercover in the muggle world with a new identity, but can his identity really fool the great Sherlock Holmes when they are thrown together on a murder case in Berlin?

'Sherlock I won't tell you again, take your coat off'

Mrs Hudson was wittering to herself over a gin & tonic when John arrived at the flat. John smiled at her appreciatively as she handed him a coffee Sherlock was stood by the window wearing his long overcoat which looked damp from the early June rain.

'Is he busy –'

'Ask me John, not the landlady,'

'Do you ever stop?' John said irritated

'No because stopping would intimate me slowing down, of which I will be doing neither,'

'No I mean being rude,'

'Rudeness is a weakness.'

'No,' said John quickly 'being rude is your frequent talent,'

'Are you insulting my talents?' Sherlock replied not taking his eyes off the scenes unfolding outside.

'Sherlock- you said you needed me. Because you were snowed under' John said impatiently glancing around the flat, the laptop was sat upright and opened on several tabbed webpages. Empty coffee mugs and needles littered the small coffee table. 'This does not fill me with confidence,' he added.

'I am busy John. The world is alive. People are simple creatures, simple habits- but every once in a while an extraordinary one may just appear, and aha,' Triumphantly laughing Sherlock left his rigorously held stall by the window and beamed positively at John.

'Sherlock this day would be a lot better if you told me why you needed me-'

'My dear Watson, since when do I ever need to give you a reason?'

Harry smirked. He knew he had won when he saw the flicker of silver slide from the scabbard, his enemy had made his final mistake. The blade pierced through the air in quick succession and Harry, exhilarated by the turn in his fortune ducked out of the way seamlessly.

'You won't take this from me,'

'I have no plans to take it from you, I just needed to know where it was.'

And with a clean sharp strike of his wand the long narrow blade evaporated from his enemy's hand.

'WE SAID NO WANDS,'

Felicity Barrass shouted.

Harry spun round grinning at the Defence Secretary sitting up high in her office from where she was viewing their latest Auror Training session with colleagues from the Muggle Liaison Office.

'I didn't use my wand,' said Harry smartly

'Non-Verbal magic Mr Potter is still magic. And NOT THE AIM OF THIS EXERCISE'

Harry snorted. Hadn't he proven himself growing up with people like Dudley Dursley that he was more than capable of using muggle techniques than wizards double his age?

'You cheated Potter,' said his opponent 'you just can't stop yourself from showing off can you?'

'I didn't cheat, Matt' he protested 'I just used my imagination – a muggle can't see a non-verbal attack can they?'

'It isn't the point,' said Matt 'we are supposed to be learning – we can't learn if you constantly break the rules,' pointedly glaring at Harry then glancing up towards their superiors.

Harry stiffened following Matt's gaze.

'I think on my feet, like you all should,' Harry said loudly. He heard the distinct sound of the office door slamming and Felicity was striding down the stairs towards them, her gold muggle attire wound tightly around her slight body.

'I will not have my agents disagreeing so formidably in front of the Senior Partners,' she hissed seething. Her dark toned skin shimmered in the overhead lights of the training room. 'Both of you need to understand each other- you are partners. You need to both learn to keep your cool if that can be achieved!'

'Harry you have one week till you will be deeply undercover in the muggle world, and you Price- well you could do better. One Week gents, then there will be no more practice. And you will be in the heart of the biggest case the MLO has ever undertaken,'
