"They were the footprints of a gigantic hound!" Those canine tracks in Arthur Conan Doyle's The Hound of the Baskervilles set the great Sherlock Holmes sleuthing on the trail of a murderer. It was a case of art imitating etymology. When Middle English speakers first borrowed sleuth from the Old Norse word slōth, the term referred to the track of an animal or person. In Scotland, sleuth hund referred to a kind of bloodhound used to hunt game or track down fugitives from justice. In 19th-century U.S. English, sleuthhound, soon shortened to sleuth, began to be used for a detective. From there, sleuth slipped into verb use to apply to what a sleuth does.
