Oh yeah. Actually, I wasn't interested enough to keep everyone straight... the last book I read, by Paul Kavieff, was fairly academic in nature, really getting into the nitty gritty of the trials, etc. But since probably not a lot was known about the guys personalities, etc., there weren't many memorable characters.
But it talked a lot about the Burnsteins, Keywells and Axlers. But, they all just kind of blended into a mass of your garden-variety gangsters, without too much memorable about them, for the most part. Except maybe Harry Shorr.
