Very easy and fast read. It would have been the type of book I would have adored as a kid in that liminal space where high reading skills put you beyond children's books but maturity does not really afford you adult reads. So yeah, classic adventures for the win.
The devise of telling the story from the third limited of a character other than the Scarlet Pimpernel allows for a show of his BAMF qualities that would have sounded boastful otherwise, so that's another good bit.
Most of my gripe comes from the ever moronic woman (I'll leave the political and racial alone this time). We are constantly told she's the cleverest woman in Europe, but either that's a huge fail of informed quality, or the author was taking the mickey on it by drawing a contrast of what the world says of a characters intelligence vs what happens behind curtains of a person's life. Still, the fact that she's absolutely useless and most times an obstacle, continued to bother me. I thought the story would redeem her when she decides to go to France, that we would be shown her being resourceful and clever and see her save the day right alongside the Pimpernel. Hell, for a bit there I was prepared to be blown out of my mind by a turn of the XX century female author writing a woman saving the hero. Alas, no dice.
The other bit that is a bit weak (beyond several un-reveals, duh), is the constant over explaining. Orczy does an excellent job of showing the pieces so that you can puzzle it out. It is a pity she wastes pages and belittle her readers intelligence by spelling it all out yet again in expository dialogues and what not.
Anyway, if you are not nit-picking like I've been, it is good entertainment.
