(Original Review, 1980-04-03)
I just read this book by Niven; it looks new (first printing April 1980), and features Gil the ARM. Standard Niven with some new psychic hand abilities. (Would you believe searching in a hologram like dowsing over a map). Also, another laser murder, however nothing so creative as the one where the light originated in a time-retarded field. One thing he never explains - why are lunar ("Lunie") courts so quick to mete out justice?
