Tad Dameron knew the interstellar cops would call him a murderer, as he looked down at the remains of his friend and partner from the Non-Terran Affairs Bureau. But Tad knew different, for within the barely recognizable corpse at his feet lurked a freakish parasite. Tad knew his lost love, the beautiful Dian, had also been possessed by it - and destroyed. This is where his investigation of Bjonn, and his Church of the Brotherhood of Life had led him - to the murder of his partner. He was on his own, now - and did he really have the full story?
