Mick Coyle returns with a new documentary.
Over the last few months he's uncovered some uncomfortable truths about the fate of Britain's mental asylum graves.
Lost Souls investigates:
More than a quarter of a million bodies lie nameless in unmarked and largely forgotten graves around the UK, bodies belonging to people who died in Britain's Mental Asylums.
Some of those sites sit in plain sight in our communities, have been neglected, or even sold off.
One now houses a children's playground.
In our exclusive investigation, Senior Correspondent Mick Coyle looks into what happened to those who died while in the Victorian mental system, why it still matters today and uncovers uncomfortable truths sitting at the heart of our towns and cities.
