She’s disappeared off the radar. Knollys was the subject of various historical romances which were at one time quite widely read, eg “The Rose of Raby” , but these went down the memory hole after WW2. They weren’t particularly well written, but that is not necessarily a draw back. If a movie producer had picked it up and cast someone like Vivien Leigh, it could all have been different. Who gave a toss about Thomas Cromwell before Hilary Mantel made him the subject of the “Wolf Hall” trilogy, two of which won the Booker Prize?
