Just published in English - Bernard Heuvelmans' book on the Minnesota Iceman (originally published in French in 1974). The book was translated by Paul Leblond and features an all new afterward by Loren Coleman.
Here's the book description:
"'NOW IN ENGLISH FOR THE FIRST TIME… THE TRUE STORY OF THE MINNESOTA ICEMAN!'
"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."
