The Cryptid Files: A Documentary Investigation
By Steven Knight
Length5h 42m
About this audiobook
They've always been dismissed as folklore. But the classified documents tell a different story.
Drawing on thousands of pages obtained through Freedom of Information Act requests, declassified military files, and decades of field investigation, former CIA analyst Steven Knight applies the full weight of intelligence methodology to the world's most enduring cryptid mysteries. From Bigfoot sightings logged in National Park Service incident reports to government-suppressed encounters in Afghanistan, from the documented Mothman sightings preceding the Silver Bridge collapse to military sonar contacts with unknown deep-water organisms — the evidence has always been there. It was never released.
The Cryptid Files is not a book of campfire stories. It is a case file. Fifteen chapters, fifteen creatures, one question that intelligence professionals have quietly asked for decades: what if some of them are real?
The files are open. The investigation begins now.
