The Patient Dervish

Istanbul.

Coveted city of emperors and sultans, and home to an ancient mystery both men and monsters have died to protect. From the twisting back streets of Old City to forgotten Roman cisterns deep underground, Rev. Emil Stone and Misha "Puzzle" Kaslov follow clue after clue to unlock the greatest secret they've ever chased. Pitted against scholars, Sufis, clerics, and terrorists, Emil and Puzzle find themselves questioning the motives of their supposed allies… and their own orders. They soon face an unthinkable possibility.

Perhaps some secrets aren't meant to be uncovered.
