Sam Goldwyn is alleged to have said, "What we need now is some fresh clichés".
That's what this book is achieving.
It's a boys-own-adventure where the adventurer is a young woman with a self-confidence and knowledge of the world that would make Holmes look shy and make Watson blush. This simple inversion, combined with a cute-meet involving taxidermy, a hero who provides eye-candy as well as competence and a few set pieces where our heroine bedazzles the soon-to-be-but-not-quite-yet hero with her knowledge, wit and sheet impertinence make this very entertaining.
I think Sam Goldwyn would have bought the film rights on the spot although I'd rather see it done by RKO with Howard Hughes directing.
