The opening story in the Doctor Who TV canon, this is [a:Terrance Dicks|4768|Terrance Dicks|http://d202m5krfqbpi5.cloudfront.net/authors/1283004803p2/4768.jpg]' novelisation of the first four-episode story arc of the same name: [b:An Unearthly Child|18310727|Doctor Who An Unearthly Child|Terrance Dicks|http://d202m5krfqbpi5.cloudfront.net/books/1376346903s/18310727.jpg|1761975]
. Barbara and Ian, two school teachers, are worried about one of their students – Susan. She has some strange behaviours; appears to know far too much about some things and far too little about others. So they decide to follow her home one evening and confront her strange, autocratic father, who identifies himself only as the Doctor. The rest, as they say, quickly became history (and future, and present on other worlds, etc.) as the Doctor whisks them all away in his Tardis to the dawn of time (and a 50 year TV career).
Novelisations have a tendency to be a bit one dimensional, but Dicks brings a depth to the secondary characters here that just wasn't present, or possible, in the TV episodes. Whether this is Dicks embellishing the screenplay to make the novel read better or if there was detail in the original script that wasn't apparent in the episodes isn't clear, but it works. The secondary story featuring the cavemen is really only a device to introduce us to the characters and premises of this, and future, stories. And while well told (arguably better than the original TV episodes) it's always going to be difficult to try and cram a real plot into such a short story while also introducing four central characters and the beginnings of the science-fiction back-history of the Tardis and its capabilities.
