Celeste Bradley's "The Impostor"
Couldn't get past the first appearance of the hero. He's a Lord something or other, i.e. a member of high society and listed in Debrett's Peerage. But he dresses up in clownish clothes as a disguise and arrives at a society ball in London, gets announced under a false name, and he (or the author) thinks no one will recognize him? Just preposterous. Evidently the author has never thought through the implications of being a part of high society, although it is not that hard - think of celebrities today, or New York high society.
