Craig Paul Alexander Hinton was a British writer best known for his work on spin-offs from the BBC Television series Doctor Who. He also wrote articles for science fiction magazines and was the Coordinator of the Doctor Who Appreciation Society. He taught mathematics in London, where he was found dead in his home on 3 December 2006. The cause of death was given as a heart attack. Hinton first was known for his articles about science fiction television programmes, including Doctor Who and Star Trek. These brought him to the attention of the editor of Marvel UK's Doctor Who Magazine, who offered him the job of reviewing merchandise for the magazine's Shelf Life section. Whilst writing for the magazine, Hinton had his first novel published. The Crystal Bucephalus was part of Virgin Publishing's Missing Adventures range. The book - which Hinton often jokingly referred to as "The Crystal Bucket" - was originally submitted for Virgin's New Adventures, and 50,000 words of this version were written before the change was made. This novel was followed by a further Missing Adventure, Millennial Rites in 1995, and then by Hinton's only New Adventure in 1996, GodEngine, which features the Ice Warriors as well as oblique appearances by the Daleks. Following Virgin's loss of their licence for Doctor Who merchandise, Hinton began submitting proposals to BBC Books. In 2001 they published his novel The Quantum Archangel as part of their BBC Past Doctor Adventures range. This was followed in 2004 by Synthespians™. This had started life as a proposal for the Eighth Doctor before being adapted to a previous Doctor. An image of the television show Dynasty was used on the cover: the cover's creators had arranged for permission to use the copyrighted image, but had neglected to get permission to alter it. At the last minute a replacement cover had to be produced. It is this that appears on the cover. Hinton's Doctor Who novels often contain references to or explanations of elements of past continuity. He claimed to have been the originator of the term "fanwank", which he applied to his own work. Hinton continued to work with Virgin, writing pseudonymously under the name Paul C. Alexander for their Idol range. He wrote three books in the range: Chains of Deceit, The Final Restraint and Code of Submission. These titles were a major departure from his science fiction. They explored aspects of his sexuality only suggested in his other works. Hinton wrote for Big Finish Productions' Audio Adventures. The play Excelis Decays was produced in 2002 for their Doctor Who range and The Lords of Forever in 2005 for their The Tomorrow People range. Hinton also wrote short stories for their short fiction collections. Outside of the science fiction world Hinton was a noted IT journalist in the UK. He edited magazines in the mid-1990s for VNU Business Publications in London and moved on to ITNetwork.com shortly afterwards.

Christopher Bulis is a writer best known for his work on various Doctor Who spin-offs. He is one of the most prolific authors to write for the various ranges of spin-offs from the BBC Television series Doctor Who, with twelve novels to his name, and between 1993 and 2000 he had at least one Doctor Who novel published every year. Bulis' first published work was the New Adventure Shadowmind, published in 1993 by Virgin Publishing. This was the only novel Bulis wrote featuring the Seventh Doctor, and his next five books were all published under Virgin's Missing Adventures range: State of Change (1994), The Sorcerer's Apprentice (1995), The Eye of the Giant (1996), Twilight of the Gods (1996), and A Device of Death (1997). When Virgin lost their licence to publish novels based on Doctor Who, Bulis repeated this pattern writing novels for the BBC - with one novel written for the current incumbent Doctor as part of BBC Books' Eighth Doctor Adventures range, and then all of his other novels published as part of the Past Doctor Adventures range. Bulis' novels for the BBC were The Ultimate Treasure (1997), Vanderdeken's Children (1998), City at World's End (1999), Imperial Moon (2000) and Palace of the Red Sun (2002). Bulis also wrote the novel Tempest as part of Virgin's Bernice Summerfield range of novels, and also a short story for Big Finish Productions' Short Trips series.

Marc Platt is a British writer. He is most known for his work with the BBC science fiction television series Doctor Who. After studying catering at a technical college, Platt worked first for Trust House Forte, and then in administration for the BBC. He wrote the Doctor Who serial Ghost Light based on two proposals, one of which later became the novel Lungbarrow. That novel was greatly anticipated by fans as it was the culmination of the so-called "Cartmel Masterplan", revealing details of the Doctor's background and family. After the original series' cancellation Platt wrote the script for the audio Doctor Who drama Spare Parts. The script was the inspiration for the 2006 Doctor Who television story "Rise of the Cybermen"/"The Age of Steel", for which Platt received a screen credit and a fee. He lives in London.
