 In 2011 Andrew MacGregor Marshall published online  in which he describes the genesis of The Devil's Discus; 
"Krueger wrote it on the suggestion of Prince Subhasvasti, brother of Prajadhipok’s wife Queen Rambhai... [Subhasvasti] came to trust and respect Pridi as a result of their wartime cooperation...He believed – that Pridi had nothing to do with Ananda’s death.The Devil’s Discus was envisaged as a way of rehabilitating Pridi’s reputation in the hope that he would be able to return from exile and play a leading role in Thai politics once again."
