Richard III Society
Langley is the President of the Scottish branch of the Richard III Society. She attributes the discovery to a feeling she had when first visiting the northern end of the Social Services car park where the king was later found, having gone to Leicester for the purpose of finding out more about the historical figure for a screenplay she was writing; other members of the Richard III Society had suggested the three central car parks location as long ago as 1975 but an oversight in footnoting gave no evidence for it. According to Langley, "the first time I stood in that car park, the strangest feeling just washed over me. I thought: 'I am standing on Richard's grave'." She proceeded to fundraise, organise and commission the excavation of the site, leading to the eventual discovery of Richard III's remains. She later contributed to a documentary about the project, titled Richard III: The King in the Car Park based on her original Looking For Richard Project.
She is co-author, with Michael K. Jones, of The King's Grave: The Search for Richard III (US title: "The King`s Grave: The Discovery of Richard III’s Lost Burial Place and the Clues It Holds"). In 2013 Langley was working on the screenplay for a proposed film on the life of Richard III, in which she hoped Richard would be portrayed by English actor Richard Armitage, who was himself named after the king.
In July 2017 Langley objected to a plan to stage Shakespeare's play Richard III at Leicester Cathedral, on the basis that it was contrary to the undertaking by the Dean of Leicester, made in March 2015, that the king would be reburied in the Cathedral "with all dignity and honour". The play was staged in sold-out performances at the cathedral on 19 and 20 July.
In 2014, Langley detailed the years of research behind the Looking For Richard Project that got her to the northern end of the car park in Leicester in search of the church and grave in Finding Richard III: The Official Account of Research by the Retrieval & Reburial Project. The co-authored work includes chapters from Looking For Richard Project members, Dr. John Ashdown-Hill and Dr David and Wendy Johnson and is edited by Annette Carson.
