Book excerpt: Endings always hurt, but Vitali Grigorenko never expected a nightmare in orbit. Assigned to command the last flight of the orbiter Baikal, Vitali had started the mission in a nostalgic mood. That went out the airlock when he saw the body tumbling through space just beyond the flight deck windows. A body in NASA blue, not Russian tan. Now he's trying to get to the bottom of a murder in space, and his own country's space program as much a hindrance as a help. It's becoming clear that politics is involved, on both sides of what used to be the Iron Curtain, and he's going to need to go clear to the top. A short story of the Grissom timeline.
