This was a solid police procedural, with particular emphasis on the ‘procedural’. I cannot recall reading a novel so relentlessly bogged down in description of every aspect of a crime and how it is investigated and solved. The plot was decent, though somewhat tied up in conspiracy and political aspects that didn’t excite me much. The characters were well-rounded but often a little flat - I suspect as number twenty-something in the series, the author is a little tied down in terms of his recurring themes and people. I would also have liked a bit more humour, more colour, more quirkiness. As it was, it felt very middle of the road - I’ve read a lot worse, but it doesn’t compare IMHO with McBride, Oswald, Mina, Brookmyre and Robertson. More like Val McDermid and Ian Rankin, not really my kind of Scots crime novel.
