A very quick read. This felt like a bridging volume, transitioning the series from the previous loose trilogy of Cormac solving mysteries in the face of police corruption, to whatever comes next. Which appears to be a supporting cast change and handling internal corruption and misconduct investigations among the garda. Of course, the focus on stopping bad cops serves to reinforce the notion that there are good ones, but you can't really get away from that in this genre.

As with the last few in the series I enjoyed the careful investigative work, but there didn't seem to be much of that before we came to a rapid and convenient conclusion.
