'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.

Nice stories about Garda and famous crime cases in Ireland from a former superintendent. Nice point of view about treating people with respect and dignity, even if it is just their memory...

The first 60 or 70 pgs are a struggle but the book does get progressively better. The sisters and Drogheda fued chapters are very good. I did however prefee Pat Marrys making of a detective book, it was more succinct and flowed better. Still if your into Irish crime, this is a must.

You can tell that chief Superintendent Mangan loved his job throughout but more importantly was empathetic to people regardless of how they met. Some big cases discussed in the book firsthand with such care, empathy and dignity for the victims. He was an exceptional member of An Garda Siochana and an equally exceptional man. Highly recommend.

Really interesting read. Christy Mangan seems like a very fair and reasonable and kind man and one you would be lucky to have on the worst day of your life. Really fascinating look inside some of Ireland's most notorious cases. I particularly found the chapter about the Scissor Sisters interesting.
