"Nick must be original"

A long time ago, just starting to use the Internet, I chose a nick from one little-known book. When I wanted to read it again, I searched in the internet, but it wasn’t there! Nick was absolutely unique. A couple of years later I tried to find this book again - I did not find it, but I found two more with my nickname. It was the first time I really wanted to kill a man. Two people, to be precise.
