Exit Strategy: Book 4: Murderbot Diaries by Martha Wells – Book

Exit Strategy is Book 4 in The Murderbot Diaries Series by Martha Wells and it is the last book in the series. You’re probably getting pretty sick of hearing the term murderbot by now (although there is something horrifyingly titillating about the idea) and our own murderbot has changed his look so much that he is now actually more of a Sec/Unit (Security Unit). In the world of The Murderbot Diaries, murderbots are frightening bots, taller than humans, half constructed of organics and half non-organics, wearing armor and helmets that they can darken to hide behind. They have, we guess by reading between the lines, a reputation for being almost unbeatable, although it sounds as if combatbots can take them down. Why would people create murderbots to begin with? When you read about some of the illegal things corporations get up to in The Murderbot Diaries you can see that they might need to assassinate people who know their secret evil deeds. This is what a murderbot is, essentially, an assassin, although murderbots can also be used for protection from a universe that is still full of unknown alien things.

Our Murderbot becomes what is essentially a detective, hunting down clues to solve two mysteries at once. One mystery is to unravel whether he/it did actually go off the rails and murder a whole group of miners and their security forces (bots). The other mystery is to find out why GrayCris is filing lawsuits against the very person (Dr. Mensah) who should be filing charges against GrayCris. The corporation covers its tracks and destroys negative evidence or kills anyone who could testify. The only untethered witness snoping into their affairs is Murderbot. GrayCris wants Murderbot murdered. They really want this badly. They have lots of connections and humans don’t realize how bad the corporation is. Murderbot has only the allies he meets on his travels and he is almost reduced to parts many times as he investigates.

Murderbot has also been meeting humans who are not rapacious, greedy crooks. He  works for a few groups of humans he encounters at the various transport hubs he hitches rides to. He favors transports that have bot pilots and are on runs that are empty of humans, but as soon as he gets off a transport (with his disguised appearance – yes apparently a bot can adopt a disguise) he keeps meeting these vulnerable humans who need security but who could never afford it. He’s susceptible to honest, but naïve humans and so he helps them. It has the beneficial side effect of allowing our bot to acquire currency cards. Bots don’t get paid. They do not have money. Money is always helpful to anyone, especially to a detective though.

As Murderbot disguises itself so the corporation and HubSystem cannot find it, interestingly, its appearance gets more and more human, less and less like a murderbot. A murderbot is so distinctive it could never sneak around the universe. ART on the deep space university research transport helps Murderbot make its arms and legs two inches shorter. Murderbot stops wearing the helmet and the armor. He grows his hair. He allows his mentor to instruct the med unit (a machine) to place small hairs on his “skin”, the organic parts of him. He keeps the gun ports in his arms but organic flaps cover them most of the time. He grows out his hair. He wears human clothing. And he has the ability to hack security systems so that his presence is erased. He can also hide his weaponry from security scans.

In Exit Strategy  Murderbot must get Dr. Mensah away from the clutches of GrayCris who will do anything to stop her from escaping, as she happens to be on a transport hub that is home to their corporate offices. They are even more avid to capture her now that Murderbot is back and she seems to have evidence of what they have been up to. We can guess what fate will await each of them if caught. Murderbot also has to decide how much human contact he wants and what he wants to do next. If they make it. It is an action-packed wrap up. Later, Murderbot (perhaps).
