For info about Joseph Kennedy's Hwood fling, read Gloria Swanson's autobio. She was involved with him both personally and professionally and has a lot to say.
Jacobs' book also has info about the elder Kennedy---and what a racist he was.
I'll try to read Swanson on that sometime. I have Ronald Kessler's biography of Joseph Kennedy, which is pretty good. On Fisher, I guess that goes to show that casino investment is always a gamble--no pun intended. . .
