The Fall of the House of Usher: Why was Prospero's body full of Monty?

In the episode "The Murders in the Rue Morgue" of The Fall of the House of Usher, it is revealed that Prospero's body was filled with a street drug called Monty, which is similar to the Usher family's pet drug, Ligodone. This discovery seems to be damning evidence that could potentially ruin the Usher family's reputation. However, Arthur Pym, the family's attorney, is handling the investigations and Camille, one of the Usher siblings, is managing the media, so they are able to spin a narrative that protects the Fortunato pharmaceutical empire.While the Usher family is trying to maintain their public image, Verna, a woman with an irregular heartbeat, enters their lives. She offers herself as a test subject for Victorine's experiment, which involves a heart mesh. Verna also takes on the identity of a call girl named Crystal, participating in Tamerlane and William's domestic sexual games. Additionally, Camille, who is obsessed with finding dirt on Victorine, encounters Verna disguised as a security guard at the laboratory where Victorine conducts her experiments.The Usher family each have their own roles and ways of dealing with Prospero's death. Frederick is being groomed to take over the family business, Tamerlane runs her own wellness empire, Leo is a master of video games, Victorine works in science and medicine, and Camille is responsible for shaping the family's public image. Camille is determined to turn Prospero into a charitable genius in the media's eyes and use his death to discredit Auguste Dupin, who is investigating the Usher family.Despite their seemingly callous and utilitarian approach to grieving, the Usher family is not without their own internal struggles. Roderick blames Frederick for not demolishing the building where Prospero held his party quickly enough, and Leo's drug-infused celebrations often end with unintended consequences, such as the death of his boyfriend's cat. These actions are sure to come back to haunt them.It becomes clear that Prospero's death was not accidental, just like the deaths caused by Ligodone. Madeline Usher, the matriarch of the family, is aware of this. Camille, suspecting Victorine as the family's informant, investigates the animal trials at RUE Morgue and discovers discrepancies in the number of chimpanzees entering and leaving the facility. Victorine has been falsifying her test results and replacing dead monkeys with living ones, pumping them full of adrenaline to make it appear that her heart mesh is successful.Camille is delighted to find damning evidence against her sister but faces a setback when her assistants, Toby and Tina, reveal that they are now in a romantic relationship and will no longer participate in the sexual aspect of their professional relationship. Camille fires both of them, unaware that she will have to continue the investigation alone.Determined to expose Victorine's deception, Camille enters her lab, where she is confronted by Verna disguised as a security guard, who tries to warn her not to proceed. Ignoring the warning, Camille enters the room where she discovers stitched-up and agitated chimpanzees. Verna jumps on the surgical table, revealing her own stitched-up chest, shocking Camille. Camille snaps a photo with her phone, and in an instant, Verna transforms into an enraged ape, attacking Camille. The next morning, the lab is covered in blood, and Camille's mangled body lies in the corner, with a chimp nearby.In the past, the episode also explores Roderick Usher's rise to power within Fortunato Pharmaceuticals. After discovering that the company has acquired the rights to Ligodone without involving him, Roderick confronts Mr. Griswold, the company's top dog. Mr. Griswold offers Roderick a promotion and financial incentives to maintain his loyalty. Roderick's wife, Madeline, sees this as an opportunity for Roderick to eventually destroy Mr. Griswold when the time is right.Overall, the discovery of Monty in Prospero's body raises questions about the Usher family's involvement with drugs and the mysterious circumstances surrounding Prospero's death. It also highlights the complex dynamics within the Usher family and their determination to protect their empire at all costs. The episode sets the stage for further revelations and intensifies the suspense surrounding the Usher family's dark secrets.
