This book, originally published in 1998, has been republished as part of the 50th anniversary celebrations of Doctor Who, and epitomises the Second Doctor story of choice for those celebrations. Justin Richards has written a lot of books, including a lot of Doctor Who novels.
In the canon of Doctor Who, this story is set to occur after The Ice Warriors, and features the Second Doctor with Jamie and Victoria. The Doctor and his friends land on a prison planet, where the prisoners and the guards have their own routine. But that's all about to change, as the politics of a large and powerful Republic impinge on honour and glory, and ambition and greed come to the fore. But, as with all Doctor Who stories, nothing is ever quite as it seems, and this story has plenty of twists and turns before it all comes to a satisfactory end.
The humour of the Second Doctor is nicely captured in this story, as are the gestures and mannerisms that Patrick Troughton so neatly put into his characterisation. This is a really good Doctor Who story, and one I'm glad I had the chance to catch up on. Totally recommended.
