Its fun, i like his books, but I kind of find that often the genre is a bit unsatisfying - crime/detective fiction. I have been to Istanbul a few times, its one of my favourite cities, i wish i could go more often but in the meantime Yashim, is really a great character - and you really have to be cutout for this kind of work. His books are always an interesting stroll around the history of the suburbs of the old city.
Again we are transported to old Istanbul and the activities of Jason Goodwin's great characters. His interesting plot keeps us turning the pages until the unexpected ending. His descriptions of time and place are excellent.
