What do you do when you've buried four husbands and not yet found a fifth? Wealthy Lady Bumstead takes a cruise down the Mekong in Vietnam with a hired female companion, Anne de Tonkin. Annie is not just a kind old lady, she is a brilliant listener and soon knows all about the other travellers. But, on the last day of the cruise she is murdered. Lady Bumstead, unable to see any reason why Annie should be murdered, is convinced the killer was after her. She hires the SeeMs Detective Agency to protect her and find the killer. At the same time she decides to do some sleuthing herself, and, with the help of her high powered hearing aid, she begins listening to all the conversations around her. As the SeeMs Detectives investigate the crime, they find Annie had a rich past and connections with almost everyone else on the boat. There seem to be plenty of reasons for killing her, but who did the deed? Will Lady Bumstead and the SeeMs Detectives find the killer before he/she strikes again? Will Lady Bumstead find a fifth husband? Or will she become another victim? Written in the first person by Lady Bumstead this novel will be particularly enjoyed by readers of Agatha Christie and A Man Called Otto. Or anyone interested in whodunnits.
