A gruesome murder of Tessa Quayle in northern Kenya sets off the action of this gripping story. The Constant Gardener is not just the story of a diplomat seeking to find those responsible for the murder of his beautiful young wife, but also a parable of the conflict between forces seeking power and money opposed by those led by human values. The title is most appropriate as Justin Quale persists in uncovering those responsible in the face of powerful and deadly opposition. The ending is sad but not unexpected as Justin in one sense does accomplish some of the goals of his most courageous wife and finds a way to reconnect with her.
Of his 23 novels, John Le Carre rates Gardener as one of his four best.
