Evil Eye, Paperback/Jason Goodwin

When the body of a Russian agent is found down a monastery well, Yashim knows exactly who to blame. Fevzi Ahmet Pasha, commander of the Ottoman fleet. Years ago, when Yashim first entered the sultan's service, Fevzi Ahmet was his mentor. Ruthless, cruel, and - in Yashim's eyes - ultimately ineffective, he is the only man who makes him afraid.
