From the Publisher:
Treasure beyond imagining waited in the temple of Ahriman, a god so evil and terrifying that even the despicable priests of Set aided in his banishment. None dared to steal the trea sure-until Conan the Cimmerian came to Shapur. Now he must smuggle tons of gold and Jewels past the city guards and escape to a place of safety, while pursued by the most effi cient and dangerous band of manhunters ever assembled, led by a warrior whose skills and ferocity rival Conan himself. But greater dangers lurk when Conan returns to the temple -- and the priests of Ahriman conspire to bring their fearsome deity back into the world...
