When the mummy of Pharaoh Seqenenre Tao II was pulled from a hidden royal cache in 1881, the wounds covering his skull sparked a mystery that would take over a century to solve. Ruling a divided Egypt around 1580 BCE, Seqenenre led the Theban resistance against the Hyksos invaders from the north, and paid for it with his life at age 40. For decades, historians debated whether he died in battle, was murdered in his sleep, or something far more sinister. Forensic radiologist Dr. Sahar Saleem uses cutting-edge CT scanning to examine his mummy in detail no one has ever seen before. What she finds will rewrite the story of how this pharaoh died, and why it changed the course of Egyptian history.
