"Song of the Death Pits!"
Conan the Thief has a plan. He is after a rare jem, the Dragon's Egg, owned by Harach-Gnar. Harach-Gnar also owns a fighting pit. Conan's scheme is to make partners with the pit master of the Zamoran Satrap, get himself consigned as a pit fighter, and take the Dragon's Egg when Satrap challenges Harach-Gnar to test their fighters.
The plan runs into major flaws. Conan's partner is discovered and killed, there is an ambitious woman pit fighter named Kara in the mix, plus Satrap is aware of the plan and wants a huge cut of the action. To top it off, the dead partner was the only one who knew the secrets of Harach-Gnar's palace.
