Clarke, a 19th-century English naturalist, roams the pampas in search of that most elusive and rare animal: the Legibrerian hare, whose defining quality seems to be its ability to fly. The local Indians, pointing skyward, report recent sightings of the hare but then ask Clarke to help them search for their missing chief as well. On further investigation Clarke finds more than meets the eye: in the Mapuche and Voroga languages every word has at least two meanings.
