A fun read, lots of Istanbul atmosphere

I didn't find the murder-mystery aspect all that interesting (and really the fact that the protagonist owns a murder-mystery bookshop wasn't played up at all), but the descriptions of places in Istanbul and the interactions between different kinds of people, different nationalities and strata of society, between the various neighborhoods and areas of the city itself, kept me reading.

Recommended especially if you're in love with Istanbul, Constantinople, and/or the idea of them.
