An Evil Eye, by Jason Goodwin

An Evil Eye is wonderful addition to the series, which is set in Turkey during the heyday of the Ottoman Empire.  The main character is Yashim, an investigator and fixer, who serves the power elite.  The fact that he is also a eunuch gives him access to both the men's and women's worlds.  In An Evil Eye, Sultan Mahmut II has just died and the political realm is kind of dicey.  Yashim needs to solve the murder of a Russian quickly before an international incident begins, while ensuring that he can keep his freedom outside of the palace.  The Bellini Card was a little dull, but in An Evil Eye, Goodwin is back in form.
