Time Patrol
Time Patrol is a series of works, mostly short stories, by Poul Anderson. They take place in a universe where the resolution to the Grandfather Paradox is that you now exist without ever have had a father, and the Time Police relentlessly works to keep time nevertheless on the same path -- while ruthlessly expurgating futures, filled with living beings, that do not conform to it. Doing this often requires the sacrifice of time travelers or those they love.
