In December 2016, a US official in Havana went to the embassy medical centre to report a debilitating and confounding  illness. The symptoms included headaches; nausea; hearing loss; problems with memory and vision – and its onset was characterized by hearing… something. A buzzing, hissing, grinding… sound.

Soon, a second official came down with the same symptoms. Then a third. Then a fourth. By the time the story went public in summer 2017, dozens of US diplomats, as well as some Canadians, had come down with what was becoming known as “Havana Syndrome.”

In this deep dive investigation, journalist Nicky Woolf peels back the layers of one of the most bizarre mysteries of the modern age. The Sound is a story about spycraft, technology, and the brain. It’s a story where, at every turn, you’re never quite sure what’s real and what’s an illusion. It’s a story about how the Cold War, maybe, never really ended.
