In October, 1977 in Edinburgh, Scotland, the body of a 17-year-old girl was found on a deserted beach. Then, just a few hours later, the body of a second teenage girl was found in a field, just a few miles away. Later, the girls were identified as friends, and had last been seen alive the previous evening at the World’s End Pub in Edinburgh. Their murders prompted one of the biggest manhunts in Scotland’s history. But it would take nearly 40 years for investigators to discover who was behind the crime.  This episode is sponsored by: Cerebral Original music by Ben Krejci, Sergey Cheremisinov, Kai Engel, Kevin MacLeod, and Daniel Birch.
