I confess to having had a shock of recognition in reading the lines written on the page “Frères humains, qui après nous vivez,/N’ayez les cœurs contre nous endurcis…“, the opening words of François Villon’s Ballade des pendus.  Not from reading Villon, so much (sadly, I am not so literate), but because Truman Capote used them as the opening epigraph for In Cold Blood.

It all connects, I guess.
