  The Trial - Day 1 & 2 (4 of 5) 12.09.2026 50min

  Extradited to Switzerland, Belshaw was taken to Bois-Mermet Prison in Lausanne, where he remained in custody awaiting trial. His defence was entrusted to two of Switzerland's leading criminal lawyers, Paschoud and Stoudmann, while Swiss investigators assembled the case they believed would finally reveal the truth about Betty's disappearance. On December 3, 1980, Cyril Belshaw stood trial for murder in Aigle. Awaiting him was not only the weight of the prosecution's evidence, but a judicial system unlike anything he would have had encountered in the Anglo-American world - one that would shape the course of the trial its outcome.RATING & REVIEW (highly appreciated)FOLLOWING (to be informed about future episodes)FEEDBACK & COMMENT (written or audio recording)SWISS MURDRER MYSTERIES WEBSITEAuthor & HostRudolph IslerGet in touchFACEBOOKINSTAGRAMLINKEDIN DonationsPayPalREVOLUTCopyrightPlayground Media Productions Ltd.Interview Cyril Belshaw©RTS

  Fight for Justice (3 of 5) 05.09.2026 36min

  Confronted with the Swiss investigators' discovery, Belshaw admitted to forging his wife's dental records. His explanation, however, raised more questions than it answered. Convinced they had uncovered only a fraction of the truth, the Swiss investigators closed in, determined to stay on the suspects’ heels. Belshaw was arrested after making what would prove to be a fatal miscalculation: Traveling to Paris for a conference, where French police were waiting. Backed by some of France's most formidable defence lawyers, he fought a determined legal battle to avoid being sent to Switzerland. The outcome hung in the balance. In the end, however, the courts ruled against him.RATING & REVIEW (highly appreciated)FOLLOWING (to be informed about future episodes)FEEDBACK & COMMENT (written or audio recording)SWISS MURDRER MYSTERIES WEBSITEAuthor & HostRudolph IslerGet in touchFACEBOOKINSTAGRAMLINKEDIN DonationsPayPalREVOLUTCopyrightPlayground Media Productions Ltd.Interview Cyril Belshaw©RTS

  The Alpine Corpse (2 of 5) 29.08.2026 40min

  Three months after Betty vanished in Paris, road workers made a grim discovery: the decomposed body of a woman near a lay-by on a remote alpine pass in Switzerland, barely 100 kilometres from Crans-Montana. Aware of the French missing-person investigation, Swiss detectives asked Cyril to provide Betty's dental records. He complied—but only after secretly altering the charts. Soon afterwards, he returned to Canada, seemingly unaware that Swiss investigators would eventually uncover not only his forgery, but an even more damaging secret. During his time in Crans-Montana, Cyril had been carrying on a clandestine love affair.RATING & REVIEW (highly appreciated)FOLLOWING (to be informed about future episodes)FEEDBACK & COMMENT (written or audio recording)SWISS MURDRER MYSTERIES WEBSITEAuthor & HostRudolph IslerGet in touchFACEBOOKINSTAGRAMLINKEDIN DonationsPayPalREVOLUTCopyrightPlayground Media Productions Ltd.Interview Cyril Belshaw©RTS

  The Belshaw Case - Trailer 08.07.2026 4min

  On December 3, 1980, Canadian professor Cyril Belshaw, a world-renowned anthropologist from the University of British Columbia in Vancouver, stood trial in the city of Aigle, Switzerland charged with the murder of his wife, Betty. Her body had been discovered 21 months earlier, along a remote Swiss mountain pass not far from where the couple spent a sabbatical. Odd: Just two months before her remains were found, Belshaw had reported her missing, claiming they had been visiting Paris at the time of her disappearance. Some things just did not add up.RATING & REVIEW (highly appreciated)FOLLOWING (to be informed about future episodes)FEEDBACK & COMMENT (written or audio recording)SWISS MURDRER MYSTERIES WEBSITEAuthor & HostRudolph IslerGet in touchFACEBOOKINSTAGRAMLINKEDIN DonationsPayPalREVOLUTCopyrightPlayground Media Productions Ltd.

  A new hot Lead (6/6) 21.11.2024 37min

  A new theory suggests that an unknown individual may have been involved in the murders, proposing that they were carried out not by one person, but possibly two or even three. This theory is supported by testimony from two witnesses, whose statements were made public by the police only years later. Moreover, a recent discovery on the internet could potentially be a groundbreaking revelation.RATING & REVIEW (highly appreciated)FOLLOWING (to be informed about future episodes)FEEDBACK & COMMENT (written or audio recording)SWISS MURDRER MYSTERIES WEBSITEAuthor & HostRudolph IslerGet in touchFACEBOOKINSTAGRAMLINKEDIN DonationsPayPalREVOLUTCopyrightPlayground Media Productions Ltd.
