But I did find a man, the diplomatic agent Comte the Montrond (Casimir de Mouret 1768-1843) who was an intimate (read, puppet) of Talleyrand, that is to say, a close friend (his mother Angelique d'Arlus was actually close to Talleyrand) who had a secretary name Antoine Boulanger whom surviving sources seem puzzled over for he acted as valet de chambre, secretary, banker, friend, counsellor and other various roles to the Comte. The reason that this was strange is that the Comte was not rich (he had been, having practiced what we call now 'insider trading') yet Antoine Boulanger had his own wealth sufficient to have a domestic servant for himself and his family and retain a family lawyer. In other words, Antoine had more money than his boss. Huh?
What's more, Casimir seem's to be a fascinating man; like a Talleyrand drawn in crayon and possibly a little 'unique'. He had a brother named Edouard de Mouret. Where did Antoine get his money? Was he the Boulanger in the English law case Talleyrand vs. Boulanger (a French money lender)? What happened to the money? Was it lost in the musical chairs of who-governs-who this week that was the early 19th century of France?
