Baynard Hardwick Kendrick (1894–1977) wrote whodunit mystery novels about Duncan Maclain, a blind private investigator who worked with his two German shepherds and his household of assistants to solve murder mysteries. The novels were the basis for two films starring Edward Arnold, Eyes in the Night (1942) and The Hidden Eye (1945). Kendrick was credited by Stirling Silliphant for being the source of the Longstreet (TV series) character about a blind insurance investigator.
