Her biographical work includes several books on King Richard III of England, and while she was still in South Africa the Looking For Richard Project was initiated in the UK and following her return in 2011 Carson was invited to join the Project as historical consultant. The Project's aim was to find the lost grave of Richard III and his mortal remains which meant excavating the same Social Services car park that Carson had written about. Of "Richard III: The Maligned King", Philippa Langley, who had founded the Looking for Richard Project said that ‘It was the first book I had read to make this claim.’. As well as being historical consultant, Carson contributed to the scripting and copywriting of the International Appeal that saved the dig from a £10,000 shortfall.
