Katie Maguire hunts down a serial killer in county Cork in the fifth terrifying crime thriller in the series

It is a sunny Saturday in county Cork, and an Irish wedding is in full swing. Drunk uncles are toasting the bride. The Ceilidh band have played for hours. No one could predict that the cutting of the cake would bring this wedding to a horrifying end. The severed head of Micky Crounan, local baker, is grinning gruesomely up from the bottom tier of his own cake. Katie Maguire, of the Irish Garda, is baffled—until another local businessman goes missing in horrific circumstances. Soon Katie is on the trail of a debt-collecting gang calling themselves The Kings of Erin. But these are very dangerous men, and they will stop at nothing to throw Katie off the trail.
