Colin Brake is an English television writer and script editor best known for his work for the BBC on programs such as Bugs and EastEnders. He has also written spin-offs from the BBC series Doctor Who. He currently lives and works in Leicester. Brake began working on EastEnders in 1985 as a writer and script editor, being partly responsible for the introduction of the soap's first Asian characters Saeed and Naima Jeffery. From there, he went on to work as "script executive" on the popular Saturday night action adventure program Bugs, before moving to Channel 5 in 1997 to be "script associate" on their evening soap Family Affairs. In the early 2000s, Brake wrote episodes of the daytime soaps Doctors and the revival of Crossroads. Away from television, Brake had his first Doctor Who related writing published as part of Virgin Publishing's Decalog short story collection in 1996. He then had his first novel Escape Velocity published by BBC Books in February 2001 as part of their Eighth Doctor Adventures range based on the television series Doctor Who. At the time, Brake was quoted as saying how appropriate it was that he was now writing for Doctor Who, as he was briefly considered as Eric Saward's replacement as script editor on the show - a job that eventually went to Andrew Cartmel instead. Brake followed Escape Velocity with the Past Doctor Adventure The Colony of Lies in July 2003, and then with the audio adventure Three's a Crowd from Big Finish Productions in 2005. His Tenth Doctor Adventure The Price of Paradise was released in September 2006. He has also written an audio for their Bernice Summerfield range, and a short story for their Short Trips range.

Jacqueline Rayner is a best selling British author, best known for her work with the licensed fiction based on the long-running British science fiction television series Doctor Who. Her first professional writing credit came when she adapted Paul Cornell's Virgin New Adventure novel Oh No It Isn't! for the audio format, the first release by Big Finish. (The novel featured the character of Bernice Summerfield and was part of a spin-off series from Doctor Who.) She went on to do five of the six Bernice Summerfield audio adaptations and further work for Big Finish before going to work for BBC Books on their Doctor Who lines. Her first novels came in 2001, with the Eighth Doctor Adventures novel EarthWorld for BBC Books and the Bernice Summerfield novel The Squire's Crystal for Big Finish. Rayner has written several other Doctor Who spin-offs and was also for a period the executive producer for the BBC on the Big Finish range of Doctor Who audio dramas. She has also contributed to the audio range as a writer. In all, her Doctor Who and related work (Bernice Summerfield stories), consists of five novels, a number of short stories and four original audio plays. Rayner has edited several anthologies of Doctor Who short stories, mainly for Big Finish, and done work for Doctor Who Magazine. Beyond Doctor Who, her work includes the children's television tie-in book Horses Like Blaze. With the start of the new television series of Doctor Who in 2005 and a shift in the BBC's Doctor Who related book output, Rayner has become, along with Justin Richards and Stephen Cole, one of the regular authors of the BBC's New Series Adventures. She has also abridged several of the books to be made into audiobooks. She was also a member of Doctor Who Magazine's original Time Team.
