I am looking for the name of a book (might be a short story) which I have read many years ago. The general plot as I remember it:
- There is a supercomputer which can predict with good accuracy the human actions in the next several days (after that, it is just less accurate).
- The computer could alert the police of future possible crimes, and would.
- The computer alerted the police that a man is going to commit a murder, and the man is placed under arrest.
- His son goes to a computer-interface station to ask the computer for help.
- The computer sends the son on a complicated quest.
Spoiler alert: I am giving away plot-sensitive details at the end, so they're hidden below.
- The son kills the computer, and we find out that the murder-alert was actually on the son (but their system automatically redirects it to the parent's name, or just a wrong identification for Mr. Surname).
- We find out the computer planned the whole thing, because it got depressed after dealing with the pain and suffering of the whole human race.
