The story begins at the end of 1968 in New Jersey, when zoologist Bernard Heuvelmans and biologist Ivan Sanderson first hear from a correspondent about the frozen corpse of an extremely hairy man-like creature being exhibited in the Midwest. Upon arrival in Minnesota, the two scientists come face to face with a “hominid” not of our species embedded in a block of ice. An inquiry into the origin of the specimen triggers a bizarre adventure involving the FBI, the Smithsonian, the Mafia, the Vietnam War, drug smuggling, Hollywood, and a secretive millionaire, giving much of the account the flavor of a riveting detective story. What happened is told in meticulous detail by Heuvelmans, who draws a startling conclusion as to the Iceman’s nature based on a comparison of its anatomy with that of modern humans and fossil ancestors. But where Heuvelman’s scientific tale ends, cryptozoologist Loren Coleman’s begins, in a lengthy fact-filled afterword that brings this remarkable saga up-to-date.
