I've been looking for something to read, lately... maybe I need to go back to the classics. A lot of them I haven't read since high school, or even earlier...
Yes, I have those books, but they didn't involve robots as murder suspects, IIRC.
Did you know they're supposedly turning both "Have Space Suit Will Travel" and "The Moon is a Harsh Mistress" into movies? Has there ever been a good movie based on one of RAH's books?
