biblio - Yes, I read & enjoyed several books by Barbara Nadel. Her plots are plausible, characters & atmosphere feel 'real', and she is a good storyteller. Myriad spelling mistakes and the odd historical error do grate a bit, but I enjoy her books overall and will probably go back to reading more when (if) I run out of books to read on my Kindle.
I would also recommend Jason Goodwin's books about Istanbul during Ottoman Empire times, with a eunuch detective solving murder mysteries involving the padishah's entourage. Again, credible fiction rich in detail, with only the spelling mistakes indicating that the author is writing about a foreign land.
