Bravo! Whereas this book does not go into great depth in evaluating individual conspiracy theories, it is an indispensible index in the library of those not easily fooled by surreptitious explanations of murders in the public forum. What's more, it serves another purpose. In bringing all of them together in one place one can see a remarkable consistency in many of them.
The most credible case for the JFK cover-up JFK and the Unspeakable: Why He Died and Why It Matters presents compelling evidence the CIA orchestrated the JFK assassination to head off his intent to pull out of Vietnam. Likewise, the most credible case for the Pope John Paul I assassination The Vatican Murders: The Life and Death of John Paul I presents much more than compelling proof the CIA orchestrated the assassination of the 33-day Pope when he motioned to give financial and arms support to revolutionaries in Central America who were fighting an uphill struggle against the coalition of the United States and ruling juntas and the CIA's Contra death squads.
Even for those who have spent a lifetime preoccupied with one or more of these cover-ups as I have, The Mammoth Book of Cover-Ups: The 100 Most Terrifying Conspiracies of All Time reveals great similarity in many of them. Start with this book as it raises the questions. Then go on to the others for the answers.
