From the author's website:
Even before Emily steps off the Orient Express in beautiful and decadent Constantinople, she's embroiled in intrigue and treachery. The brutal death of a concubine in the sultan's palace allows her first foray into investigating a crime as an official agent of the British Empire--because only a woman can be given access to the forbidden world of the harem. There, she quickly discovers that its mysterious, sheltered walls offer no protection from a ruthless murderer. Excerpt. Book #4 in the Lady Emily mystery series.
