Often referred to as one of the best, if not the best, writers on
Doctor Who (1963), his period as script editor on the series,
with
Philip Hinchcliffe as producer, is also considered by many
to be the high point of the entire series. In a poll for
Doctor Who (1963) Magazine in 1998, three of the stories voted into the top five were written by Holmes, with the other two being from his period as script editor. In fan site Outpost
Gallifrey's 40th Anniversary Poll, five of the serials from his time as
script editor were voted by fans into the top ten. Four of the stories
voted into the top ten were written by Holmes, including one he wrote
under the pseudonym of Stephen Harris. The top three were all written
by Holmes.
