Crocodile Tears is a very nicely written police procedural that has a strong blend of unpicking the mystery surrounding the death of Dermot Brennan, capturing the aftermath of the property crash in Ireland, and charting the interactions and tension between the cops and with the suspects. O'Sullivan creates vivid characterisation, particularly with respect to the guards, and rather than concentrating on a single cop traces a handful from junior to senior rank, each well penned with a decent back story. The dialogue and interactions are first rate. In particular, I thought the first interrogation with Sean Doran, a resident on one of Brennan's ghost estates, was excellent: all lies, threats, feints, and violence waiting to explode. For the most part the plot worked well, though I felt it became a little derailed towards the end as it veered towards a more fanciful ending. Overall, a very promising start to what I assume (and hope) is going to be a series and highly recommended.
