All My Sins Remembered

NO CRERTURE IN THE GALAXY IS DEADLIER THAN MAN.

Otto McGavin, one of twelve Prime Operators in the universe, worked for the clandestine arm of the trans-space peacekeeping agency as a ruthless guardian of alien rights. He traveled from planet to planet--his body encased in plastiflesh, his mind disguised by personality overlay--infiltrating bizarre alien cultures, surviving by raw instinct and violent assassination on exotic, bloodswept worlds.

And always he returned to his original self--his conscience stabbed by the memory of all those he'd killed in the service of interstellar harmony.
