Antonin chuckled when he saw the latest bit of idiocy from Umbridge. These British seemed to treasure their equality and independence and would be up in arms, with any luck. Still, perhaps it would be time to build a small fire under Draco's feet and get him moving soon.
Putting pen to parchment, he did jot off a quick letter to Fleur Weasley for Nikita to deliver...
Mrs. Fleur Weasley Dear Fleur,
No doubt by now you have seen the latest decree from your ersatz Minister.
If anyone from her office is so rude as to approach you, you may produce your certifications of being nothing of the Dark. If that doesn't immediately turn the trick, advise them that the lawyers have advised you to answer no further questions and refer them to me. By now, you and your sister should have received your international certificates as well, issued from The Hague in Vienna. I'd advise you to keep all of your paperwork with you at all times.
If they insist on taking you into custody, demand deferential treatment, offer to accompany them freely until the matter is resolved, then call for Nikita, who will immediately contact me. You will find a few new house elves about that answer to him. I will act at once to obtain your release. You may also mention, if anyone treats you in any way other than as a respected guest, that your lawyers will be filing both civil and criminal charges for false imprisonment. Then refuse to say anything more until legal representation arrives.
