Before the original "Doctor Who" series reached its conclusion, some tentative plans had been made for a proposed 27th season under the assumption that it would maintain the then-current pattern of two four-part and two three-part stories. As noted in each entry, Big Finish Productions has produced audio adaptations of several scripts as part of their "The Lost Stories" releases. The safecracking companion introduced in "Crime of the Century" (see below), who was never named during the planning, has now been given a name, that of Raine Creevey, and she is portrayed by Beth Chalmers.
