A fun follow-up to the excellent _Made to Kill_, first in the Ray Electromatic series. It isn’t perhaps necessary to have read _Made to Kill_ before reading _Killing is My Business_, as the noirish mystery in the second book is completely unconnected to that of the first book and other than the two main characters, no returning characters, though the first book does explain better some of the world building than the second book does. Though to be honest, you grasp all you need to know in _Killing is My Business_; the main character is a robot named Ray Electromatic, goes by Ray, the last robot left in the world, who works ostensibly as a private detective in mid 1960s Los Angeles, partnered with the static, room-sized supercomputer named Ada back at the office, their real business is that Ray is a hitman. Ray is physically essentially invulnerable, though he needs to recharge and change his memory tapes every night. Ray has a great many things programmed into his permanent memory, such as who he is, what he does for a living, who Ada is and the nature of the relationship, facts about Los Angeles and the area, how to drive, and how to be a private eye (which is his cover) and a hitman, but he rarely if ever remembers anything from the day before. Though sometimes he gets flashes of things he learned the previous day, he relies on Ada each morning replaying key parts of his memory tapes back to him or just telling him what he needs to know. It’s a fun premise all around.
Hard to say a lot about the plot without spoiling the story and that is really easy to do, but it is an interesting tale involving Ray doing a hit on first a person who dies before he gets to him, then another he can't find, and then finally a man he has to save before he can do the hit on, a gangster by the name of Zeus Falzarano, all for a mysterious client Ada won't spill the beans on. It has layers and layers to it, it is very noirish with double crosses and secret secrets and femme fatales and hitmen and gangsters and crooked officials and also makes use of the Los Angeles setting with Art Deco buildings and mansions in the hills of Los Angeles and lots of cars and people who came to be Hollywood to be actors and ended up being something else. Like the first book, it has some wonderful Chandlerisms, wry musings and witty, almost poetic descriptions of everyday things, of noting key aspects of a room or how a person looks but doing so in a sentence or half a sentence or painting a picture by noting the absence of certain things, or witty noirish phrases like “People liked it. Until they didn’t.”
There is a lot of action, several real mysteries, and like the first book Ray and Ada being robots/computers isn’t just what they are but their very nature and their history ultimately figure into the greater story.
Few real complaints. I think a minor loose end is never addressed again, and though there is some evolution in the relationship between Ray and Ada, I am both not sure I completely understood it and given how Ray’s memory works, not sure it mattered.
Overall, very enjoyable and a fast read.
