of Fenric by Ian Briggs suggested a fate for Ace that differed from later original novels, and Philip Martin's adaptation of the Mindwarp segment of The Trial of a Time Lord included an ending that completely contradicted the scripted ending of the televised serial. After Virgin began its New Adventures and Missing Adventures line of original novels in 1991, it also published several additional novelisations both on their own and under the Missing Adventures label. These were two Dalek stories from the Troughton era, The Power of the Daleks and The Evil of the Daleks, which — along with another radio novelisation The Paradise of Death — are considered to be the last of the Target run. Later novelisations tended to be included as part of the original novel series from Virgin. The Ghosts of N-Space, a second radio serial featuring Jon Pertwee produced in the mid-1990s was novelised, as were several non BBC spin-off video productions such as Shakedown (as one section of a larger original novel) and Downtime, adding an air of official sanction to them. In 1996, BBC Books published a novelisation of the Doctor Who television movie. A one-time return to serial novelisations occurred in 2004 when BBC Books novelised the made-for-Internet adventure, Scream of the Shalka. Several serials remain unnovelised for various reasons. Fan-written novelisations of these stories do exist, however. The unnovelised serials are: Resurrection of the Daleks by Eric Saward Revelation of the Daleks by Eric Saward Adams' stories were never novelised, reportedly because he wanted to do the job himself. However, soon after his tenure with Doctor Who ended, the author had gained considerable popularity because of his The Hitchhiker's Guide to the Galaxy franchise and became (depending upon the source of information) either too busy or too expensive (or both). Adams would later recycle elements of City of Death and the unbroadcast Shada into his Dirk Gently novels. As for Saward's two Dalek serials, Target Books was unable to come to an agreement which would satisfy both Eric Saward and Terry Nation's estate for the novelisations. Virgin tried again at a later date and authors were assigned for both books, but again an agreement was not reached. From 1988, Titan Books released script books of Doctor Who serials. This included an unproduced serial, The Masters of Luxor (written 1963–1964, published 1992) by Anthony Coburn, which would have been the second serial
