Here, at last, after 30 years, is a finished version of "Shada", the "Doctor Who" adventure by Douglas Adams that was never finished (a strike at the BBC interrupted filming, although bits were used in the later "The Five Doctors" to cover for Tom Baker's absence from that).
Gareth Roberts has done a stunning job, returning to the latest notes and versions that Adams left and, as he says in a helpful postscript, having had the luxury of time to complete what Adams was writing in a rush.
I've always been cautious about written versions of Who and never convinced that they work as well as on TV, but Roberts (and Adams, of course!) show here that it's possible. Whether considered as a Doctor Who adventure alongside all the others (including the 21st century revival) or simply as a compelling story, this book succeeds - both bring to life the characters of the Fourth Doctor and Romana and also providing foils in Clare, Colin, and Professor Chronatis, who are swept in their wake (as well as a truly megalomaniac villain).
It's also possible to see aspects of Adams' other fiction reflected here (slightly irritating talking spaceships, bad stuff that might happen with airlocks and much more - it's fun to watch out for this.)
Overall, an enjoyable read, I'd have thought a must for those who are Doctor Who or Douglas Adams fans (or both).
