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.

Simon Guerrier is a British science fiction author and dramatist, closely associated with the fictional universe of Doctor Who and its spinoffs. Although he has written three Doctor Who novels, for the BBC Books range, his work has mostly been for Big Finish Productions' audio drama and book ranges. Guerrier's earliest published fiction appeared in Zodiac, the first of Big Finish's Short Trips range of Doctor Who short story anthologies. To date, his work has appeared in the majority of the Short Trips collections. He has also edited three volumes in the series, The History of Christmas, Time Signature and How The Doctor Changed My Life. The second of these takes as its starting-point Guerrier's short story An Overture Too Early in The Muses. The third anthology featured stories entirely by previously unpublished writers. After contributing two stories to the anthology Life During Wartime in Big Finish's Bernice Summerfield range of books and audio dramas, Guerrier was invited to edit the subsequent year's short story collection, A Life Worth Living, and the novella collection Parallel Lives. After contributing two audio dramas to the series, Guerrier became the producer of the Bernice Summerfield range of plays and books, a post he held between January 2006 and June 2007. His other Doctor Who work includes the audio dramas, The Settling and The Judgement of Isskar, in Big Finish's Doctor Who audio range, three Companion Chronicles and a contribution to the UNIT spinoff series. He has also written a play in Big Finish's Sapphire and Steel range. Guerrier's work is characterised by character-driven humour and by an interest in unifying the continuity of the various Big Finish ranges through multiple references and reappearances of characters. As editor he has been a strong promoter of the work of various script writers from the Seventh Doctor era of the Doctor Who television series
