An Irish wedding is in full swing. Drunk uncles are toasting the bride. The Ceilidh band have played for hours. But the cutting of the cake will bring the wedding to a horrifying end. For there, grinning gruesomely up from the bottom tier, is the severed head of the local baker. Katie Maguire, of the Irish Garda, does not have any leads - until another local businessman goes missing in horrific circumstances. The murders appear to link to The Kings of Erin, a terrifying gang of torturers and extortionists. But these are dangerous men. And they will stop at nothing to throw Katie off the trail.
