From the back cover Baen paperback February 2003:

THIS KNIGHT IS A SAINT -- WITH A TWIST

At least you might think so if you read his curriculum vitae. You would swear in fact that this private eye of the future is honest, paying for what he gets, getting what he's paid for, with somehow a little extra for everybody to go around. Take this case, involving a matter transmitter which the inventor tested on himself -- then found his bank accounts empty and his credit cards overflowing, all done by someone whose DNA looks just like that of the rightful owner...

But that wasn't all. There was also the archaeological dig which uncovered ruins that might solve the mystery of the vanished Martian race -- except that a greedy corporation was all set to bulldoze them over in pursuit of the bottom line unless a gallant knight -- or Knight -- could come galloping up on his charger. Then there were some people who were not amused at how the Knight had foiled a sure-fire scheme worth billions, and were looking for him with heavy muscle and heavier artillery...

People in trouble and people who are trouble just seem to populate his life. And the bad guys never seem to know what hits them...
