Shadows in Zamboula — Robert E. Howard

Cannibalism was not tolerated openly in Zamboula. But Conan knew now why people locked themselves in so securely at night, and why even beggars shunned the open alley and doorless ruins. He grunted in disgust as he visualized brutish black shadows skulking up and down the nighted streets, seeking human prey--and such men as Aram Baksh to open the doors to them. The innkeeper was not a demon; he was worse. The slaves from Darfar were notorious thieves; there was no doubt that some of their pilfered loot found its way into the hands of Aram Baksh. And in return he sold them human flesh.
