I'm a bit ashamed to admit that I like the Lady Emily series. I've had a weakness for strong female detectives (including the awesome Veronica Mars tv show). Miss Alexander's writing has grown stronger and more developed with each passing novel, and it's kind of cool to see growth in an author. If you follow a character through multiple books, you want to see them grow and the author develop as well.
One of the highlights of this book was reliving a trip I made to Istanbul (Constantinople) a few years ago and getting to explore it through someone else's eyes. From a historical standpoint, it was an interesting time period before the fall of the Ottoman Empire and before the country became Turkey. I was able to retrace my own steps through the city and felt like I knew the landmarks of where Lady Emily's adventure took her.
The plot itself is interesting enough: On her honeymoon with her new husband (who, hopefully in book #5, won't disappear in Africa while big game hunting) stumbles into a mystery involving a slain harem girl and her diplomat father. The book contains really interesting descriptions of the life inside a harem, which will probably intrigue and yet disgust readers with our modern day virtues. And Emily's ingenuity and talent as a detective are put to the test as she gets deeper into the mystery.
I know that some people will say - wait, this is the Ottoman empire! How can an English woman run around all willy-nilly and solve a mystery? Well, it's fiction, but based on truth: Lady Paget and other important women who actually did mingle with Sultans. So for the most part, I'm inclined to believe that had Lady Emily existed in real life, she would have been able to do these things (Victorian women were more bound by class than being a woman.)
The only real weakpoint for me in this novel - and this is nitpicking - is that the romance between Emily and Colin needs work. I like Colin as a character, but as a couple, they seem like two people who got bored and decided to get married because they ran out of things to talk about.
Overall it's a 4.5/5 star book. This book will both appeal to readers who are already fans of Miss Alexander's works and those who want to get into the world of a very intrepid Victorian woman.
