Gail Gauthier, meet Vesper Holly.
From Original Content:
On the backflap to the 1986 hardcover of this book, Alexander says, "The Illyrian Adventure was intended as an entertainment, with a gloriously fearless heroine, legendary heroes, inscrutable mysteries, and fiendish villains." I don't know how inscrutable the mystery was and the villain was a garden-variety fiend. But the heroine, Vesper Holly, was gloriously fearless.
As I said over at Gail's, you can't beat a heroine who "has the digestive talents of a goat and the mind of a chess master ... is familiar with half a dozen languages and can swear fluently in all of them."
She would SO kick Indy's ass.
