Doctor Who: Third Doctor Books in Order

Alastair Reynolds' contribution to Doctor Who focuses on the Third Doctor, the dapper exile played on screen by Jon Pertwee, at a time when he is stranded on Earth and working with UNIT. Harvest of Time is written to feel like a lost television serial from that early 1970s era, scaled up to novel length.

The book opens with UNIT investigating strange incidents on a North Sea drilling platform, the kind of industrial setting that often featured in Pertwee's years. At the same time the Brigadier and others close to the Doctor begin to realise they are forgetting about a very important prisoner, the Master, even as the reader sees that he is being drawn into events by an outside force.

That force is a race called the Sild, crustacean like creatures who have broken out of an ancient confinement and decided to re enter history by using the Master's mind as a tool. Their attack pulls the Doctor, Jo Grant, the Master, and UNIT from familiar bases and country roads into deep time, derelict starships, and far future civilisations.

Reynolds treats the Doctor and the Master as uneasy mirror images. They argue, bargain and betray, but they also understand each other better than anyone else can. The story leans into that dynamic by forcing them into a reluctant alliance against a common enemy that threatens both their plans.

For readers who know the television stories, there are nods to other adventures from this period, but the novel is written so you can follow it simply as a self contained science fiction thriller. Expect running battles with alien invaders, questions about how time travel reshapes history, and plenty of classic UNIT banter along the way.

This page treats the Third Doctor material as its own mini series inside Reynolds' bibliography, useful if you are coming from Doctor Who and want context on where Harvest of Time sits in his wider work.
