The Missing Episodes
Talk about it here.
The Target Missing Episodes was a series of novels published by Target Books as a spin-off of their regular Doctor Who novelisations line.
They were novelisations of scripts written for season 23 but never produced due to the decision to proceed with The Trial of a Time Lord story arc instead.
Although more than three stories had been planned for the aborted season, only three were adapted. This spin-off line is notable for including the only Doctor Who novel to be written by series producer Graham Williams.
