The Fuse Volume 3: Perihelion

Klementina Ristovych and Ralph Dietrich are Homicide detectives on 'The Fuse', a five-mile long solar energy platform orbiting above the earth that's also home to Midway City, population half a million. Ristovych should have retired years ago; Dietrich is the first cop to actually volunteer for MCPD Homicide in its entire history.
