It's Egypt, 1320 BC.
The future of Egypt lies in the hands of chief detective Rahotep when he undertakes a clandestine mission across enemy empires and rogue states to deliver a top-secret letter, written by the Queen to her arch-enemy, the King of the Hittites.
It is a mission from which Rahotep may not return.
But he also has a wildly personal motive; to seek out a depraved murderer at the heart of a mysterious and brutal new opium cartel that has emerged within the criminal underworld of Thebes. His quest brings Rahotep face to face with his own dark demons, which he must conquer if he is to return home in time to save Egypt's greatest dynasty and his own family from the terror that threatens them all.
