The Devil's Discus is an investigation into the death of King Ananda Mahidol (Rama VIII) of Siam (later Thailand) by English-South African author Rayne Kruger. Book summary The book comprises four main sections which are each further divided into chapters. The section "Before" serves as an introduction to King Ananda's death, to Siam and to King Ananda's background. The next section "The Life and Death of Ananda" is ten chapters in length and details the main events of King Ananda's life, from his birth in Heidelberg in 1925 to his death by a single gunshot in mysterious circumstances at Bangkok's Royal Palace on 9 June 1946. This section introduces the main characters surrounding Ananda throughout his life and who subsequently become subjects for investigation following his death. The third section "The Trial" has eight chapters and summarises the events and arguments of the subsequent regicide trial against three Palace officials, including two appeals the trial lasted more than six years and resulted in the execution of all three defendants in 1955. The final section "Who Killed Ananda?" is Kruger's own analysis of the evidence surrounding Ananda's death, leading him to the conclusion that the only satisfactory explanation is suicide. He supports this theory with the revelation of a love affair between the young King and a fellow law student in Switzerland, Marylene Ferrari, a relationship which would not have been acceptable to Siam's royalist institutions. Publication history The Devil's Discus was first published in 1964 by Cassell. The Thai government banned the book as soon as it was published and Kruger was banned from further entry to Thailand. A Thai translation of the book titled Kongchak Pisat (Thai: กงจักรปีศาจ) by Chalit Chaisithiwet (Thai: ร.อ.ชลิต ชัยสิทธิเวช) was produced for submission as evidence in a 1970 defamation lawsuit brought by Pridi Banomyong against MR Kukrit Pramoj and his newspaper Siam Rath. The translator was the elder brother of Pridi's secretary, Vacharachai Chaisithiwet. It was secretly published by two Thammasat students in 1974 and reprinted in 1977, and circulated behind closed doors in Thailand. A local printing house involved with this Thai edition was burnt down. This translation was eventually officially banned in May 2006. Through the organisation Freedom Against Censorship Thailand (FACT), the English text was reprinted in November 2009 by DMP Publications, Hong Kong.
