Just started reading it. One quick (tiny/niggling) thing caught my eye. Montebank is normally spelled mountebank. Sorry if that's petty. (I probably don't need to spell check but maybe it's helpful)
Also: parentage instead of parontage (pg 13)
Bond 18 (pg 14) uses 'he' for the entertainer which I believe you oft avoid in favor of they. Perhaps intentional.
Excited to keep reading
