They had carried a bottle of water, a notebook, and a pair of masks made from sheets of lead. A cryptic note revealed they were supposed to swallow capsules, put on the masks, and wait. Decades later, investigators still don't know how they died ... or what they were waiting for. ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/echoes-of-the-unknown-7231698/episodes/the-lead-masks-mystery-the-dead-men-on-morro-do-vint-m/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/echoes-of-the-unknown-7231698/the-lead-masks-mystery-the-dead-men-on-morro-do-vint-m.md` — Read the agent-friendly Markdown representation of this episode resource.
