Bhutan is the setting for the first in this new series in which a zoologist, a primatologist, a cameraman and a science writer attempt to find evidence of the mythical Yeti. After spending days hacking their way through inhospitable terrain, the group find some unfamiliar hairs in the hollow of a cedar tree. Is it a Yeti? Is it a rare species of bear? Or is it a grown man floundering around the undergrowth in a big woolly suit?
