Thank you to the author for an ARC to review. An excellent end (maybe?) to a wonderful series. Harriet and her brother travel to Kuala Lumpur to visit a boys school where Jullian could teach and their ward, Will, could go to school after he finishes St. Tom's in Singapore. They stay with the assistant headmaster, Henry, and his younger wife, Edith. Harriet is not taken with Edith, who seems lazy and immature and sends her daughter, Dottie, off with the amah every chance she gets. Henry says that Edith is lonely with him working all the time and is desperate for female companionship but Harriet thinks that the companionship she craves is of the male variety. Her suspicious are confirmed when she sees Edith in an animated conversation with Mr. Stewart, a local mine manager. They are far too familiar with one another and, to Harriet's eye, it seems like a lover's quarrel. Is this why the other women in the club shun Edith, because she is having an affair? On their last night in town, Edith fakes a headache and stays behind while the rest of them go to dinner. They return to find Mr. Stewart shot dead and Edith holding the gun, covered in blood. She claimed that he was trying to attack her and she had to fend him off but if that were the case then why did she have to shoot him 5 times? Meanwhile, Curran is also in town, on his secret police mission to undercover the truth about the Topaz Club, which also gives him the opportunity to try to find his half-sister, Samrita, who was supposedly a prisoner of the club. His half-brother, Jayant, is with him but he gets sick with dengue and is in the hospital for most of the book. Jayant has been looking for Samrita since she went missing and he was the one who tracked her to the Topaz Club. Curran's local government contact, Stephens, keeps tabs on his progress and warns him to trust no one. But eventually Curran runs into Harriet and he enlists her help in interviewing a woman who was formerly a Topaz Club resident since he struck out with her husband. When Harriet arrives, it is clear that the woman is Samrita but that she is using an assumed name. Samrita begs Harriet to tell Curran to leave them alone but she does give her a postcard sent by her friend and fellow Topaz Club resident prior to her death. It is believed that before her death, she snuck out sensitive documents and hid them and the Topaz Club will stop at nothing to get them back. The documents, Curran believes, are the pictures they are using to blackmail government officials into doing their bidding. Curran sneaks into the club but is captured and kept prisoner with Samrita, who they kidnapped when they killed her husband because they believe that she knows where the documents are hidden. Curran is left to die by the Topaz Club owner, who is his former lover, Li An's, evil brother. But Harriet and their friends rescue him and together, with the clues on the postcard, they find the documents. They lure Li An's brother and his partner, who turns out to be Curran's government contact, Stephens, into a trap and they are caught by the police. Curran gets his job back with the police and he proposes to Harriet and they are married in the epilogue. Edith went on trial and was convicted, a murder that was based on a real life story. Edith, jealous that her lover had dumped her for a native woman with whom he was currently living, killed him rather than let him go. I highly recommend this excellent final installment of the series.
Update: According to the author, she changed the ending and eliminated the epilogue that I refer to above so I’m not sure exactly how it ends but it seems that she plans more books with Harriet and Curran so I can’t wait to get me hands on ‘em!
