Could two different murders the team are investigating be linked? What are the ties with the South? Will North and South be able to cross borders and work together? This, the 14th story featuring the Belfast Murder Squad, is just what I would have expected - a twisty crime tale with a bunch of personal storylines in the squad (and for one of the team things could not get any worse).
With several characters from earlier in the series making appearances it helps to have read the other books but The Tribes works well as a stand alone novel too - but be warned, if this is your first meeting with Marc Craig and his team you'll be wanting to get the rest of the set.
