Bert, I have not read Conan Doyle's "Sir Nigel" or "The White Company". I have read the Sherlock Holmes stories and "The Lost World", and I thought they were marvelously well written tales. "The Lost World", in particular....it's a simply wonderful flight of imagination. It's a shame they have never managed to make an even half-decent movie based on it, but that's Hollywood for you.

For one thing, they insist in implausibly putting some good looking women (at least one, anyway) in the expedition party (for the usual reasons) which inevitably screws up the story utterly....the chances of a woman going along on such an expedition at that time in history would have been virtually nil.
