Susan Morrison and Louise Welsh swap tales of Scotland's darker history in a spooky special, finding out who gets buried in a bog and getting up close and personal with an accused witch from the early 1700s - Lilias Adie. Susan heads to Dundee University to reconstruct Lilias’ face while Louise Welsh goes to visit what remains of a person who became a bog body, to look at the reality behind one of Scotland’s most famous Gothic novels The Private Memoirs and Confessions of a Justified Sinner by James Hogg.
