MIT is incredibly busy, there has been a spate of major crimes in the area and it's not stopping. For DI Helen Grace this means trouble. Her close confidante Charlie is on maternity leave and her team is being riven by internal politics driven by her ex-lover Hudson plus the local press is wasting no opportunity to criticise. Each crime is violent but they all seem unrelated, a disparate group of people murdered with no clues. However something seems to indicate that this is not random but Grace may not have the time to investigate.
I love the DI Grace series and this is no exception. For a police procedural it is nicely balanced between crime, psychological motives and personal issues which works well. Here I'd worked out the motives and modus operandi fairly quickly but the pace really picks up towards the end and the final section is satisfying in the fact that there is no clear conclusion.
