Dexter (42)


 * For other individuals named Dexter, see Dexter (disambiguation).

Miss Dexter was a low level security agent working for Mr Saxon, entrusted with the task of finding the Doctor and his companions. Miss Dexter enlisted Francine Jones's help, tapping and tracing Francine's phone conversations with her daughter Martha, who was travelling with the Doctor at this time. (DW: 42)


 * No clear indications exist that Miss Dexter was aware of "Saxon"'s true identity or of the extraterrestrial origins of either him or the Doctor.

She was at the Joneses' house when Mr Saxon ordered her to arrest all of the Jones family and bring them to the Valiant. Dexter arrested Francine, Clive, and Tish Jones. (DW: The Sound of Drums)

Behind the Scenes
This character's name was never revealed on screen. Like Trinity Wells, her name is derived solely from the credits. In her case, she was the "Sinister Woman" in 42, but "Miss Dexter" in the cast of characters for The Sound of Drums.
