thieves, rogues & chancers

by uzwi

Can anyone help me locate a book? Title & author long forgotten. Popular in the late 1960s & 70s. It claimed to be the memoirs of a criminal–I think a Frenchman–who had sold arms & drugs around the Mediterranean in the preceding twenty or thirty years. His prison experiences featured. That’s all I can remember. Maybe it was a Corgi paperback. It was a kind of cross between Genet and Shantaram. & is there a name for this genre–very popular in the 1920s & 30s? The reminiscences of thieves, rogues & chancers who portray themselves as politicised?
