The Lead Mask Mystery

In one of the most baffling mysteries of all time, two men in Brazil follow a chilling

plan, only to face a fatal end. Known as the “Lead Mask Men,” their

cryptic journey begins in August 1966 when a kite-flying child stumbles upon their lifeless bodies

on a hill. They're dressed in suits, raincoats, and—bizarrely—handcrafted

lead masks over their eyes. No visible injuries, just a disconcerting scene.

Nearby lies a note: "16:30 be at the specified location. 18:30 ingest capsules, after the effect

protect metals await mask signal." This sounds like something straight out of a spy novel.

The investigation hits a wall when their decomposed bodies reveal no cause of death.
