Case of the Disappearing Dervish

A religious scandal. A deadly homecoming.
Moustafa Ghani El Souwaim has come far in life. Raised illiterate in a remote village in the Soudan, he set out at sixteen to better himself. His journey took him to the great archaeological sites of Africa, where he became a leading researcher versed in several ancient and modern languages. His life took an even stranger turn when he teamed up with Sir Augustus Wall and his street boy sidekick Faisal to solve murders.
Now there's been a murder in his village. A local religious mendicant has been found bludgeoned to death and Moustafa's cousin, who is in the same religious order, has vanished and is assumed to be the killer. Moustafa must return to his roots to clear his cousin's name and reunite with the family he left behind.
But can Moustafa really go home again after having changed so much, and does that home even want him?
