Private message to Lucius Malfoy

Lucius.

I just took a call from Stephen Rosier. It seems Hogwarts is in an uproar over an altercation you had with Alecto Carrow last night after the Governor's meeting.

Please tell me you did NOT in fact duel Miss Carrow in the corridors of Hogwarts with an audience of aghast students? That this is surely an outrageous and invented rumour invented by fevered imaginations of hysterical adolescents?
