Just when you thought the invasion of excellent Irish crime writers — a group nicknamed Celtic Noir — had ended, along comes Stuart Neville with his first novel. Its central character, Gerry Fegan, is a former IRA “hard man,” a killer in Northern Ireland, now reduced by the coming of peace to a shambling drunk, haunted by the ghosts of 12 victims who follow him everywhere. In a Belfast bar, “Fegan looked at each of his companions in turn. Of the five soldiers, three were Brits and two were Ulster Defence Regiment. Another of the followers was a cop, his Royal Ulster Constabulary uniform neat and stiff, and two more were Loyalists, both Ulster Freedom Fighters. The remaining four were civilians who had been in the wrong place at the wrong time. He remembered doing all of them, but it was the civilians whose memories screamed the loudest… They’d been with him since his last weeks in the Maze prison, seven years ago… He told one of the prison psychologists about it. Dr. Brady said it was guilt…” The only way that Fegan can kill off his ghosts is by tracking down his IRA superiors who ordered their deaths. This he does with violent precision, one by one, until he is alone again. Along the way, Neville condenses the fear and hate that troubled Ireland for so long, at the same time creating a memorable character with ease and a cool, deceptively straightfoward writing style.
