Chère Mademoiselle Katherine

” (it began)⁠—“I trust that you are in good health and that the return to the English winter has not proved too depressing. Me, I prosecute my inquiries with the utmost diligence. Do not think that it is the holiday that I take here. Very shortly I shall be in England, and I hope then to have the pleasure of meeting you once more. It shall be so, shall it not? On arrival in London I shall write to you. You remember that we are the colleagues in this affair? But indeed I think you know that very well. Be assured, Mademoiselle, of my most respectful and devoted sentiments.
