Prof's quiet life in 1920's London is shattered when a woman in his church is murdered and, shortly afterwards, his uncle is incarcerated in a mental asylum. Prof visits his uncle and is told wild tales of elder gods, secret cults and hidden facts about Humanity’s past. He refuses to believe the ravings but later, they remind him of a mystery from his own past. He solves that mystery and is shocked at its consequences. He travels to Egypt and there, amongst the dunes and ancient stone edifices, he finds out what really happened in Antiquity, millennia ago.
A race begins for Prof; can he help his uncle and solve the strange murders besetting London or will dark forces that are watching his every move bury those Ancient Secrets, and him with them?
