What possible connection could there have been between George H.W. Bush and the assassination of John F. Kennedy? Or between the C.I.A. and the assassination? Or between Bush and the C.I.A.? For some people, apparently, making such connections was as dangerous as letting one live wire touch another.

Here, in anticipation of the 50th anniversary of the JFK assassination in November, is the first part of a ten-part series of excerpts from WhoWhatWhy editor Russ Baker’s bestseller, Family of Secrets: The Bush Dynasty, America’s Invisible Government and the Hidden History of the Last Fifty Years. The story is a real-life thriller.
