Adam Hall's Quiller series, William Forstchen's Civil-War/Fantasy series.

One of the very best African books IMO is James S. Rand's Run For the Trees.

S.M.Stirling's Draka series is good but his later stuff is somewhat more fantasy-oriented than I like.

Anything by Dick Francis and any of Lawrence Block's later works.

Geoffrey Household's Rogue Male is a classic and many of his other works are also very good. I especially enjoyed his The Adversary, also published as Dance of the Dwarves or similar.

I have read Robinson Crusoe at least 8 times now over the last 55 years.

You can lead a man to logic but you can't make him think. NRA Life since 1976. God bless America!
