Sirs or Madams,
I regret that I am unable to consent to remaining in this strange and confounding place at this time. Even if it were not necessary for me to return to my intended, I have important duties to attend to in my home of England, chief among these being the continued slaughter of the horde of Unmentionables that plagues the country. Should you not acquiesce to my request to be returned to my land, I shall be forced to react with violence, and I assure you that this course of action would not end well for you. For your own sakes, I implore you ro return me to Hertfordshire at once, lest you meet your end at my blade.
Regards,
Fitzwilliam Darcy
