In 1997, Dr Marie Cassidy arrived in Dublin from Glasgow. There to discuss a possible deputy state pathologist post with Professor John Harbison, instead she was whisked by police escort to a Grangegorman murder scene. There was no turning back. She became Ireland's State Pathologist from 2004 until 2018, her image synonymous with breaking news of high-profile cases - a trusted figure in turbulent times. Here, with the scalpel-like precision and calm authority of her trade, Marie shares her remarkable personal journey from working-class Scotland into the world of forensic pathology, describing in candid detail the intricate processes central to solving modern crime. She recounts her work following the tragic deaths of Rachel O'Reilly, Siobhan Kearney, Robert Holohan, Tom O'Gorman and others - along with the Stardust exhumations and lesser known cases from her long career - outlining the subtle methods by which pathology and the justice system meet. Beyond the Tape is a unique behind-the-scenes journey into the mysteries of unexplained and sudden death - by turns poignant, stark and deeply compelling.
