London detective Thomas Pitt is investigating the murder of a junior diplomat by a notorious Egyptian woman and her lover, a senior Cabinet minister involved in negotiating the conflict between Egypts cotton growers and Englands textile industry. Lovat, the diplomat, once served in Egypt, and to unravel the mystery of his death, Pitt travels to Alexandria, where he finds that the beautiful Ayesha Zakhari is not who she appears to be--and that Lovats murder may be tied to an old crime which, if exposed, could set the Middle East aflame. While Pitt is in Egypt, his wife, Charlotte, occupies herself with a more mundane matter--the disappearance of a valet whose sister is a friend of the Pitts housemaid. Its not long before the reader realizes the connection between the two crimes; meanwhile, Perry layers this smoothly plotted mystery with a fascinating history of Egypt in the days of the British Empire and the religious and economic tensions whose repercussions still resonate more than a century later. Perry, the author of two Victorian-era series (the other stars investigator William Monk), does her usual fine job of bringing the colorful time period alive, helped along by the details of domestic life provided by her protagonists wives, interesting and accomplished women who have lately played all but equal roles in solving their husbands cases.
