a really good, intelligent, complex, and riveting police procedural by the creator of helen mirren's inspector tennison series and one of the most revered english mystery writers. the plot follows the police work of DI anna travis, who's much nicer than tennison but also someone who's serious and passionate about her work. i am impressed by the way in which la plante manages to focus entirely on the crime while also conveying a whole lot of what goes on between the various police officers involved. the investigation dynamics are all about figuring out an extremely complex series of murders, but at the same time, subtly, they tell us much about how people work together and how they bring their frustrations, rages, hang-ups, and longings to their work. very well designed, and fast, and compelling.
