Last week, we learned that sad news that Justin Richards, former Doctor Who books editor, and prolific novelist, had died.

Justin was a powerhouse in the worlds of Doctor Who literature, writing for the majority of the Doctors, for the BBC, Virgin and Penguin, as well as crafting a number of factual books.

We pay tribute to him with a look at his 50th anniversary novel, Plague of the Cybermen.

Justin - thank you. Vale.
