Dear Mr. Cornwell: In a January 16th posting, Frederik Prins mentioned that he was interested in the Crusades. I would highly recommend to him the following three excellent novels by Robert Shea: “All Things are Lights”, “The Saracen:Land of the Infidel” and “The Saracen:The Holy War.” They deal with the 7th Crusade of King Louis IX of France (1250 AD) and its aftermath. All three books are out of print, but multiple used copies are available for a nominal price through on-line used book services like alibris.com and abebooks.com. He will really enjoy them.
