Beneath the streets of the French capitol lurks a city of the dead: the Paris Catacombs.

Why they were piled up there is a dark and fascinating story, that includes everything from the bloody days of the French Revolution, to the making of 'corpse candles' and a mystery man found amongst its passageways.

Joining Anthony and Maddy for today's episode is the fantastic Cat Irving, Human Remains Conservator for Surgeons’ Hall in Edinburgh, to take us down to this underworld.
