The BBC is granted extraordinary access to the lives of those who work in Edinburgh's City Mortuary, one of the largest and busiest in the country. With more than 2000 suspicious, sudden or unexplained deaths investigated by the Procurator Fiscal in the capital each year, it's the job of the forensic pathologist and the mortuary staff to establish how and why they died. Over several months the BBC filmed inside the mortuary to paint a moving portrait of how we die in 21st Century Scotland.
