Erickson contributed generally single episodes to a wide variety of
British television shows, most typically of the
crime drama genre, although he did occasionally generate
science fiction scripts. In the 1950s, he would have generally been considered a
B movie or
telemovie writer. By the 1960s, however, his work was almost exclusively for
episodic and
anthologic television. He sold three scripts for the third season of
The Saint, adapted
William Tenn's short story, "
Time in Advance", for
Out of the Unknown, wrote
The Ark for
Doctor Who, and contributed to
The Inside Man and
Paul Temple. In the 1980s he
novelised his
Doctor Who story
The Ark for
Target Books. ==Personal life==
