Missing Remnants by Amy J Hamilton
Track is the best detective the Si-Cross 4 station has. He has been forced to take three months off, just as a woman dies at his front door after asking for his help. Suspecting an outbreak, the Authority submits Track to a gruelling decontamination process, while someone ransacks his apartment and dismantles his pet robot dog, Banyon. With little help available to him, Track undertakes the investigation the Authority insists on closing within hours. He’s being followed. He has no backup. His trusted colleagues are avoiding him. Someone is pretending to be his dead husband. Will Track survive to solve the mystery of the Missing Remnants?
