When an Irish vigilante group is targeted by a killer, Jack Taylor must unravel the deadly mystery. Edge is an organisation set up to rid Galway of criminals and abusers who have evaded the law. Its members include the most powerful figures in the city.

The Vatican is not pleased when it hears one of its priests has joined Edge. Who better to intercede with Father Whelan than Jack Taylor, the whiskey-swigging ex-cop who has one foot in the pub and another among Ireland’s clergy?

The day after Jack speaks to Whelan, the priest is found dead, hanged in his own back yard. Would Edge really kill one of their own? And if not, who would be bold enough to take them on? It’s up to Jack to nail the culprit before Galway descends into vigilante chaos.
