Modern Collins (8) : Condition Purple

Collins Crime Club novels, especially in the latter decades of the series, often featured quirky and genteel amateurs but "Condition purple" by Peter Turnbull is a hard police procedural set in Glasgow. 

We follow a team of worn down detectives piecing together the evidence from the murder of a prostitute and uncovering a trail of vice, drugs, hopelessness and ultra violence.

This is a great read, a tasty bit of crime with a well thought out trail of evidence. Strong yet flawed characters add to the quality of the read.
