And probably a book that should be devoured by the Vashti Narada.

Goodalls book is less interested in that early career but prefers to focus on his involvement withWho.

It has been assembled from an assortment of interviews and articles culled from the press or the internet.

And not necessarily the most obvious places.

Nor is it reassuring that he misspells not only Mark Gatisss name but also Big Finish.

Such carelessness with fact-checking does not promise a literary masterpiece.

In another universe, that could be referred to as padding.

As a result, Goodall fleshes out his bones with discussion of the series and the assorted high-profile assistants.

That might make the book more appealing to the casual reader who hasnt bought into the magazine and merchandise.

It makes it a lightweight read and light years away from an insightful biography.

Now that hes moving on, the best years, I suspect, are still ahead of him though.

Surprisingly more invaluable is the glossary at the back which explains the meaning of most technical and production terminology.

A space filler until it regenerates into a more authoritative volume.
