Doctor Who Order of The Daleks (2016) Mike Tucker Audio CD

In the Galactic Census, idyllic Strellin is recorded as a Grade Three planet – its inhabitants possessing neither advanced technology, nor knowledge of other worlds. Accordingly, Strellin is protected: landings by off-worlders are strictly prohibited. Unless, of course, those off-worlders are officials of the Galactic Census itself, come to investigate the origin of a mysterious sub-space signal – a signal no native of Strellin should be able to send.
