As I said, I don't own the book, but perhaps it is a later edition. It was hardcover. After searching Amazon.com, it appears the edition I'm referencing is the 1992 hardcover. But I thought that there was much more than 15 pages about RFK (perhaps I'm muddling sources).

John H. Davis (I think that's who you mean) is a good Kennedy historian imho, as I've already mentioned, and is related to Jackie Kennedy.

And Frank Ragano, yes, that old chestnut. He's the one who comes up with the quotes from Marcello like "we should've killed Bobby, not Johnny" and "take the stone out of my shoe," both in Italian which I can't remember right now.
