Everything About Fiction You Never Wanted to Know.

Traces is a series of six Science Fiction crime novels by Malcolm Rose. They center around sixteen year old Forensic Investigator Luke Harding and his partner in law, the Mobile Aid to Law and Crime (Or Malc for short), as they solve crimes in an alternate England where blacks are the majority race and the southern parts of the country are derelict slums.

The series starts with Luke passing his FI examination, only to quickly be thrust into his first case when a series of murders occur in the school that all seem to point to him being the perpetrator. After solving the case he's stationed in London due to the abundance of crimes in the South, which puts pressure on his already forbidden relationship with Love Interest Jade Vernon.

Tropes used in Traces include:

Ian: I don't want to be down there when they start to lay the foundations, do I? That wouldn't be much fun.
