Good, but a bit of a disappointment after the other three cracking books in this series. The storyline regarding human trafficking was probably not, sadly, at all far fetched. However, some of the scenarios and stages in the story involving the police probably were a bit beyond the pale. 
 I'd still pick up the next one in the series though, but Max doesn't need to make quite as many references to his "BMW X5". Starts to grate after a while.
