Martin Ridge was approaching retirement after a long career with An Garda Siochana. Posted to a quiet corner of Co. Donegal, he found himself investigating one of the most horrific series of child sex abuse cases in Ireland.

At Christmas 1997 a local priest Fr Eugene Greene reported to the Gardai that a man had tried to blackmail him. His hubris set in motion a Garda investigation which revealed him as a serial child sex abuser for decades. As word of the investigation spread, 26 men came forward. Most were from the tiny Gaeltacht parish of Gort an Choirce. All had been abused by Greene as children.

Soon after, another man came forward to say that he had been sexually abused by local schoolteacher Denis McGinley. As Ridge dug deeper, he discovered that McGinley had been systematically abusing children in his classroom for decades. He had at least 50 victims.

The Greene and McGinley cases both involved the Catholic Church. Greene was a priest, and McGinley a teacher in a Catholic school answerable to religious managers. As Ridge investigated, he discovered that the Church knew about the abuse, but ignored the problem. Breaking the Silence is a brilliantly written account of the Garda investigation that brought two serial and unrepentant abusers to justice.
