A fascinating, deeply personal journey inside of some of the most high-profile and grotesque crimes of the past four decades . . . a rare insight into the darkest recess of human nature Paul Williams, Irish Independent

After a forty-year career in the gardaí Christy Mangan knows how hard it is to solve a murder. Now, in Cracking the Case, he takes a deep dive into how investigations are run.

The book includes infamous and iconic cases such as that of Fr Niall Molloy whose violent death after a high society wedding became a source of feverish conspiracy theories; the notorious Scissor Sisters case in which two sisters killed and dismembered their mother’s abusive lover; and the tragic murder of teenager, Keane Mulready-Woods, as part of a gangland turf war in Drogheda.

In these and other fascinating stories, Mangan details the care investigators take in trying to give victims' families answers and to see justice done. He also shows a deep understanding of the complex reasons people are drawn into crime or commit unthinkable acts.

Cracking the Case is a remarkable insight into the mind of a gifted garda working at the highest level.

Christy Mangan retired at the rank of chief superintendent in 2022.
