Thanks for the tips I'm going to my favorite bookseller tomorrow .
Check out Wilbur Smith , a South African author who writes some azzkickin novels involving treasures
on the African continent .
I've read Smith. He writes swashbucklers like romance novels for men. His series (can't recall title) about the English sailing family's legacy in African waters is great.
I detect the history: I've visited archives up & down the entire US East Coast, Bahamas, Jamaica, Kew, The Hague, etc. Have yet to go to Seville or S.American archives.
