Chpt 31: #3. What happens to Chauvelin?

The Chauvelin is still waiting for Percy in the wrong place............ and at the very end we learn;

"It is also a fact that M. Chauvelin, the accredited agent of the French Republican Government, was not present at that or any other social function in London, after that memorable evening at Lord Grenville's ball."

Was he fired or something?
