Doctor Who: Deceit

'Take Arcadia apart if you have to.'          The middle of the twenty-fifth century. The Dalek war is drawing to an untidy close. Earth’s Office of External Operation is trying to extend its influence over the corporations that have controlled human-occupied space since man first ventured to the stars.           Agent Isabelle Defries is leading one expedition. Among her barely-controllable squad is an explosives expert who calls herself Ace. Their destination: Arcadia.           A non-technological paradise? A living laboratory for a centuries-long experiment? Fuel for a super-being? Even when Ace and Benny discover the truth, the Doctor refuses to listen to them. Nothing is what it seems to be.
