Kil'n people - David Brin

Al Morris is a private investigator. Actually, he's lots of private investigators. For he lives in a world in which every person, every day, can be in any number of places at the same time. It's the world of dittos. It is our world. Welcome to the future.

In a business where information is the currency, Al's dittos are loaded. And with a number of cases on the go at once, it is crucial that Al keeps track of what's going on. What he doesn't know is that he is about to be drawn into a plot that could throw this delicately balanced world into chaos. It seems that the technology has been developed for dittos to replicate themselves. It seems that real people may no longer be necessary. And, suddenly, it seems that mankind's dream of immortality could turn into a nightmare.
