One of the mummies inside the Cairo Museum's Royal Mummy Room is not like the others. Among the meticulously preserved remains of Egyptian pharaohs and queens lies the corpse of Seqenenre Tao, whose mummification was hurried and incomplete. His face is brutally injured and his hands are horribly contorted. Who was this man, and what on earth happened to him? We use modern forensic techniques to examine this 3,000-year-old forgotten pharaoh and reveal the probable cause of his death.

The eruption of Mount Vesuvius wreaked havoc on the Roman cities of Pompeii and Herculaneum 2,000 years ago, burying them in ash. But there's a forgotten chapter to this tragedy, involving a mass grave of 300 men, women, and children, unearthed in a Herculaneum boathouse in 1982. Found among the corpses: the mummified remains of a man, separated from the others, armed to the teeth and carrying a cache of gold and silver. Was he a hero or a villain? Scientists look for clues in the ancient city and on the body itself.
