contribute – one of the better received novels was The Also People by Ben Aaronovitch. Terrance Dicks, the author of many Target episode novelizations and a writer and script editor for the TV series going back to the 1960s, contributed a number of novels. Barry Letts, former producer of the series during the Jon Pertwee era, contributed to the Virgin Missing Adventures line. Despite moving to the BBC line of novels, the writers (many who cut their teeth with the Virgin series) attempted to maintain continuity with the Virgin range and many elements from this series appeared in later Doctor Who stories. With Big Finish Productions acquiring the licence to produce both Doctor Who and Bernice Summerfield audio plays and short fiction, they have been able to set audio plays within the universe of the Virgin novel line, as is the case with The Shadow of the Scourge and The Dark Flame, for example. Although the continuity of the audio plays and the BBC's Eighth Doctor Adventures diverge sharply from each other, they both broadly appear to maintain continuity with the Virgin series; Big Finish's early Bernice Summerfield works did not. Adaptations Paul Cornell's 1995 novel, Human Nature, as noted above, formed the basis of a two-part episode of the television series broadcast in 2007. This was the first time a full-length original Doctor Who novel had been adapted for television, although Cornell (who also wrote the teleplay) had to make substantial changes to transform his Seventh Doctor novel into a story featuring the Tenth Doctor. Big Finish Productions produced audio drama adaptations of the novels Birthright and Just War, altering them to remove the Doctor and his various companions and focus on the character of Benny Summerfield. In October 2012 a special adaptation of Benny's debut story, Love and War was published with Sylvester McCoy as the Seventh Doctor and Sophie Aldred as Ace, to mark the 20th anniversary of the character's début. Due to the success of what was planned to be a one-off release, Big Finish continued the line with an adaptation of The Highest Science, again featuring Sylvester McCoy and Lisa Bowerman in their respective roles, in December 2014. Also produced were Russell T. Davies' novel Damaged Goods, starring Sylvester McCoy, Travis Oliver and Yasmin Bannerman as the Seventh Doctor, Chris Cwej and Roz Forrester respectively, released in May 2015; Theatre of War and All-Consuming Fire
