The novel “Elegy for Angels and Dogs” by Walter Jon Williams was published for the first time in 1990.

A group of noble people and rich industrialists, all immortal, are the Party Set, a group taking part to a tour across the solar system to have parties in which panoramas that include planets and moons are the background to entertainment that also includes new drugs. Ordinary people can only watch those parties from afar to be updated on what immortals are up to.

Even in an apparently idyllic situation within a group of people who are supposed to represent the peak of humanity, crimes are committed. In that situation, a murder can have unpredictable repercussions.
