Among all the dispute and conjecture that has surrounded the life of Catcher in the Rye author
JD Salinger, one mystery remains especially puzzling. What did he produce after ceasing to publish his writing in 1965, and will it ever be read? It seemed possible that more work would come to light after Salinger’s death in 2010. In 2013 a documentary and accompanying book claimed, among other things, to describe the contents of five new Salinger books that would be forthcoming by 2020 at the latest, yet here we are at his centenary and there has been no sign.
