The Murderbot Diaries by Martha Wells is a fun series for all fans of space and science fiction. This particular addition to the series is called Fugitive Telemetry. When our Murderbot removed his governor module and became aware of his intended purpose he was aghast. He really was not at all inclined to go around murdering humans, although it was much easier with evil humans. Much of the world at this time is run by corporations who have their headquarters in the corporate rim. GrayCris is one of the worst, willing to commit all kinds of mayhem for profit.
Murderbot met up with a research space lab piloted by a bot named ART. ART and Murderbot did not get along well at first. MB turned ART on to the videos of his favorite soap operas and saved the ship from an attack. Art helped MB use the medical unit aboard ship to change himself into a less obvious Security unit or Sec Unit. But he still has his guns in his arms so, if necessary, he will kill in self-defense or to save his new human cohorts.
Murderbot saved Mensah, the leader of Preservation Station, a semi-utopian independent colony established outside the corporation rim. She had a run-in with GrayCris and MB saved her. She took MB, now a Sec Unit, home to Preservation where he lived as the only augmented human. Sec Unit didn’t like humans much, but he did like Mensah and he knew GrayCris would come after her again.
But that’s not what happens in Fugitive Telemetry. This time Sec Unit solves a murder on Preservation Station, a very rare occurrence. What he uncovers is a crime we find fairly common on earth and his investigation involves a rescue. He also makes some headway in becoming accepted by the Preservation police force. Just a little candy bar of a story in the grand scheme of things; fast, nutty and satisfying.
