From #1 bestselling author Brad Meltzer, a riveting collection of wild historical conspiracies from around the world and across the eras, including Hitler's interest in capturing the Roman "Spear of Destiny," the Kennedy assassination (did Oswald act alone?) and Area 51.

This richly illustrated book serves up those fascinating, unexplained questions that nag at history buffs and conspiracy lovers. Meltzer sifts through the evidence, weighs competing theories, separates what we know to be true and what’s still––and perhaps forever––unproved or unprovable, and in the end, decodes the mystery and arrives at the most likely explanation.
