What if the infamous Lead Masks Case wasn’t a one-off tragedy, but the final step in a years-long chain of dangerous experiments? In part 2, we pull back from the image of two dead electronics technicians on Vintém Hill to uncover a much bigger world of underground spiritist circles, secret ham radio messages, strange explosions near the beach, homemade electrical devices, and an earlier death that seems to mirror the case almost exactly. As the pattern widens, the story becomes far darker and more unsettling: not just a mystery about what happened that night in 1966, but whether the clues that could have explained everything were ruined by the investigation itself.

In tonight’s dead letter, we’ll take you through the brutalist monuments and ancient layers of Sofia, Bulgaria looking for what may have been the scene of a localized timeslip. After giving up the search for a playground that made a pronounced childhood impression, our listener Vili, stumbles right into a beautifully preserved version of it. We’ll discuss the folklore of missing time, and how our own memories might just be powerful enough to physically manifest things we wish to recover that don’t exist anymore.

In one of Brazil’s strangest unsolved mysteries, two electronics technicians travel to Niterói in 1966, buy matching raincoats, hike up a remote hill with cash, water, towels, and a handwritten set of bizarre instructions, then turn up dead days later lying side by side on palm leaves, wearing homemade lead eye masks and showing no clear cause of death. What follows is a case that spirals far beyond a simple true-crime puzzle, with every answer leading to a bigger question: were these men victims of a bizarre accident, participants in something occult, or did they believe they were about to witness something not of this world?
