Query: langston blue

I have enjoyed following Robert O Greer telling us the exploits of protagonist C J Floyd; each novel reveals a bit more fully the colorful character and depth of personality => especially as mirrored by the multi-dimensional supporting cast C J Floyd surrounds himself.I found Langston Blue the best book yet in the series, riveting, well researched => the topics Greer covers make one think as well as be entertained.
