The Fuse, Volume 3: Perihelion — Antony Johnston

A DAY OF CHAOS ― 22,000 MILES UP! 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. Previously, cases have taken them from the very bottom to the top echelons of Fuse society, and everywhere in between. But now it's Perihelion ― the day when the Earth, and therefore the Fuse, is closest to the Sun. And on this ‘Day of Chaos', the population of Midway City seems to go a little bit crazy! All leave is cancelled, all hands on deck... and for the MCPD, all hell is about to break loose! Whereas the previous books followed Klem and Ralph through a single case over several days, ‘Perihelion' follows them over the course of a single day, dealing with multiple cases ― from homicides to bomb threats and more besides!
