The 1964 murder of a nationally known cancer researcher sets the stage for this gripping exposé of medical professionals enmeshed in covert government operations over the course of three decades. Following a trail of police records, FBI files, cancer statistics, and medical journals, this revealing book presents evidence of a web of medical secret-keeping that began with the handling of evidence in the JFK assassination and continued apace, sweeping doctors into coverups of cancer outbreaks, contaminated polio vaccine, the arrival of the AIDS virus, and biological weapon research using infected monkeys.
That is an interesting read. Also, very intriguing how it is intertwined with the JFK assassination. Reading this post makes me want to read this book again, good thing I already own it.
