"Police found a horrifying journal alleging the mind-boggling activities of all three brothers....it contained explicit allegations of homosexual activity concerning Dave, Ed, and Tom, including preferences for sadomasochism, a history of their homosexual activity, and details of their wives' knowledge of the brothers' homosexuality.""The journal also recorded their alleged use of male escorts."
It looks bad, but I'm not sure what the implications are.
Blackmail is one possibility that come to mind.
