Emilia Fox, criminologist Professor David Wilson and ex-detective Dr Graham Hill revisit the Templeton Woods Murders. In March 1979, the body of 18-year-old Carol Lannen was found just outside Dundee. Less than 12 months later the body of 20-year-old Elizabeth McCabe was found in the same area. Both had been strangled. David, Emilia and Graham investigate both cases and uncover some explosive new evidence that convinces them that they know who's responsible.
