The series was initially produced by Michael Cox, with later episodes produced by June Wyndham Davies. It was developed for television by screenwriter John Hawkesworth, who also wrote many of the episodes (all based on individual Conan Doyle stories). Other writers to adapt Doyle's stories in the series included Alexander Baron, Jeremy Paul, T.R. Bowen, and Alan Plater. A full-scale outdoor replica of Baker Street was constructed at Granada's studios in Quay Street, Manchester, which later formed a central part of the Granada Studios Tour tourist attraction, before that venue's closure in 1999.
