Lady Emily and Colin Hargreaves are on their honeymoon tour, headed to Constantinople via the Orient Express. On the train, they assist Sir Richard St. Clare after he falls ill at dinner. In appreciation of their help, Sir Richard invites the couple to attend an opera at the sultan's palace. As guests are leaving, the body of a harem girl is found. She's identified as Sir Richard's missing daughter, who was kidnapped by bandits over 20 years ago. Emily is determined to exhibit her sleuthing abilities and discover the truth, but is it worth the personal price she'll pay? Because this is the fourth book in Alexander's Victorian series (after A Fatal Waltz), characters have been well established, but their relationships and inner conflicts continue to develop in interesting ways. Curious facts about the Ottoman Empire, comparisons of women's independence there and in England, and vivid descriptions of locations and objects add that little something extra. VERDICT The strong female lead and historically accurate details will please readers of Anne Perry, Laurie R. King, and Deanna Raybourn seeking a new fan-favorite author.
