Nice early finish with this (despite Paul McKenna!) as it was online at 7pm last night, but in 31a: Don's nameless billet-doux for the Princess of France - i have capo for the answer - where does the princess of France come into it??
I would like to find out how capon (castrated cock) came to mean a love-letter" by Shakespeare's time:seems very paradoxical! So far have only learned the French word "poulet" has the same meaning. Any more learned scholars out there?
