Thanks for the information both to you and the person who replied below. Are there any books that are about la famiglia in STL or Detroit?
There are 2 books on Detroit:
"The violent years: prohibition and the Detroit mobs" by Paul R.Kavieff
"The Detroit true crime chronicles: tales of murder and mayhem in the motor city" (although this one isn't only about the Italian mafia, but other organizations too) by
Scott M.Burnsteinand about St.Louis:
"Gangs of St.Louis" by Daniel Waugh (covers the period until the 1930s)
Some of the later events are featured in
"Crooks kill, cops lie" by Timothy C.Richards (although it's mostly about the bombings by the Syrian-Lebanese groups rather than Cosa Nostra)
There is also the book
"Egan's Rats: The Untold Story of the Prohibition-Era Gang That Ruled St. Louis" by Daniel Waugh, although I haven't read it yet.
