Having read all of the authors previous books set in Instanbul, I was really looking forward to this one. I found it very disappointing, I felt it was too ambitious, and the plot quite unconvincing & contrived. It lacked rigour, intoducing too many disparate elements to cover in any depth. The introduction of Inspector Ikmen's prodigal son, was very far fetched. I apologise to those of you, whom like myself are Nadel fans, but I felt so disappointed after finishing the book, I wanted to share my views.
