John Peel continues his run of excellent Who books with this, the first story of Patrick Troughton's incarnation of Doctor Who. It is a favourite of mine anyway - I cannot understand why fannish opinion generally prefers the later Evil of the Daleks - but Peel, equipped with David Whitaker's original scripts (retrieved, apparently, from his ex-wife's attic) and benefiting from some editorial decision to give him 250 rather than 125 pages to tell the story, has done an excellent job.
On reflection, it's also because this is a relatively unusual Dalek story, presenting them not as a rival galactic empire to us humans but as in some way a dark reflection of our own desires about ourselves. The only other televised story that comes close to doing that is Robert Shearman's Ninth Doctor story.
Anyway, Peel turns a good TV story (as far as we can judge, since it is one of the lost ones) into a good novel. An encouraging start to my reading up on the Second Doctor.
