Episode Schedule: September 2025
Episode 4 – Sunday, September 7th: “Radio Silence”
When Music Becomes Murder
The month opens with a chilling mystery that combines classical music with deadly consequences. The discovery of an apprentice’s body inside a giant organ immediately establishes an atmosphere of both grandeur and horror, as the very instrument designed to create beautiful music becomes a tomb for its victim.
The investigation takes a darker turn when a second body is found nearby, suggesting a pattern that goes beyond simple murder to something more systematic and calculated. As Astrid and Raphaelle begin piecing together the evidence, they must consider an unprecedented possibility—could the music itself be the instrument of death?
This episode explores the intersection of art and violence, questioning whether beauty and danger can be intrinsically linked. The organ, traditionally associated with sacred music and spiritual elevation, becomes a symbol of how something pure can be corrupted for deadly purposes. The detectives must navigate between rational investigation and the possibility that they’re dealing with forces beyond conventional understanding.
The “deadly pattern” suggests a killer with both musical knowledge and a twisted understanding of how sound and music can be weaponized. As the investigation unfolds, viewers are challenged to consider whether the murders are the work of a human killer using music as a method, or if they’re witnessing something that transcends normal criminal behavior.
Episode 5 – Sunday, September 14th: “Circe”
Ancient Powers in Modern Times
The investigation shifts to darker, more primal territory as Astrid and Raphaelle confront a case that echoes ancient fears and modern feminism. The discovery of a young woman burned and murdered in a forest immediately evokes historical witch trials and the violence historically perpetrated against women accused of supernatural powers.
The missing newborn adds urgent emotional stakes to the case, transforming it from a murder investigation to a potential child rescue mission. The vulnerability of the infant creates additional pressure on the detective team while raising questions about whether the baby was taken for ordinary criminal reasons or as part of something more sinister involving the alleged witchcraft.
The feminist group named Circe—after the powerful sorceress from Greek mythology who transformed men into animals—introduces complex themes about women’s empowerment, ancient knowledge, and the thin line between liberation and vengeance. The group’s connection to the murder raises questions about whether they represent genuine feminist activism, dangerous extremism, or something supernatural.
As the detectives “uncover dark secrets,” they must navigate the intersection of modern gender politics and ancient beliefs about women’s power. The episode challenges viewers to consider how historical persecution of women as witches connects to contemporary discussions about women’s rights and autonomy, while also questioning whether some powers might be more than metaphorical.
Episode 6 – Sunday, September 21st: “Golem”
When Technology Creates Monsters
The series ventures into science fiction territory as modern technology intersects with ancient Jewish folklore. The murder of a tech company partner immediately establishes the corporate world as a backdrop for exploring how the pursuit of profit and innovation can lead to dangerous consequences.
The “signs pointing to a mythical golem” create fascinating tension between ancient legend and modern reality. In Jewish folklore, golems are artificial beings created from clay and brought to life through mystical means to serve their creators. The episode’s exploration of how this ancient concept translates to contemporary AI technology provides rich material for examining humanity’s relationship with artificial intelligence.
The “lifelike AI project” represents the modern equivalent of golem creation—humans attempting to create artificial life that serves their purposes. As Astrid and Raphaelle investigate, they uncover the dangerous territory of technological development that attempts to replicate or replace human consciousness and decision-making.
Watching their “prime suspect spiral” provides psychological drama while illustrating the theme that “playing God comes at a cost.” The episode examines how the desire to create life—whether through mystical clay animation or advanced artificial intelligence—can lead to unforeseen and potentially deadly consequences for the creators.
Episode 7 – Sunday, September 28th: “The Book”
Ancient Knowledge, Modern Greed
The month concludes with a case that combines high-stakes art dealing with esoteric knowledge and deadly consequences. The manuscript auction setting immediately establishes an atmosphere of wealth, culture, and the competitive world of rare book collecting, where ancient knowledge becomes a commodity.
The auctioneer’s poisoning creates immediate drama while raising questions about who would kill for access to rare manuscripts and why the Corpus Hermeticum—a collection of ancient Greek and Egyptian philosophical and religious texts—would be worth committing murder to obtain.
The swap of the original Corpus Hermeticum for a fake introduces elements of art fraud and suggests a sophisticated criminal operation that goes beyond simple theft to organized deception. The choice of this particular manuscript is significant, as the Corpus Hermeticum contains foundational texts for Western esoteric tradition, alchemy, and hermetic philosophy.
As Astrid and Raphaelle investigate, they must navigate the world of manuscript dealers, private collectors, and possibly individuals who believe the ancient texts contain actual magical knowledge rather than just historical significance. The case explores how ancient wisdom is commodified in modern times and what people will do to possess knowledge they believe holds power.
