Doctor Who and the Three Doctors is your fanboy dream type of story - team up all three incarnations up to that time of the Doctor. This actually works a little better in prose than on tv I think, as it is a little easier to explain, link and interact than with the technology etc. available at the time.

A pretty reasonable story knocked together to facilitate the whole thing so that fun can be had.

So many Doctor who books - and so often badly written. I collected them all for a long time - but this is the only one that sticks in my memory. I loved it when I was 9 or 10. An insight into the time lords, and the first three Doctors with just the right amount of suspense. ( )

This is one of the novelisations that is so much better than the original that the TV version is a real disappointment - the stupid music, the lousy special effects, the clumsy resolution of the story all either absent or fixed on the printed page. It is not one of the great novelisations but it is nonetheless very enjoyable. ( )
