I write in haste to share with you a small Volume that contains information with which we should become conversant prior to the Masked Ball. It explains how to communicate with our various beaux using fans and gloves. You, in particular, dear Vittoria, will wish to ensure that Sir Unicorn is able to comprehend you! Although it has occurred to me that we shall be in quite a fix if our partners do not share our knowledge of these niceties. I attempted to ask brother Charles if he owns such a manual and his response was unhelpful and a little rude.
