Second paragraph of third chapter:

It might be thought that they had been paired deliberately as comic contrast. But they hadn’t. Van Statten didn’t have that sort of sense of humour. And now as he swept into the Cage operations room, they both snapped to attention and saluted. They knew that their boss wouldn’t acknowledge them, that he probably wouldn’t even notice they were there – but it was the correct form of the thing. If they were surprised that he’d brought the intruder with them they didn’t show it. They were paid not to be surprised.

Great novelisation of one of the great New Who episodes. You have seen the show, here's the writer's cut, as it were, giving new background to a number of the characters, smoothing out a couple of plot kinks, with combination of tight-third for Rose interspersed with notes from the omniscient narrator explaining what was happening. We lose a couple of the good lines ("He's a bit pretty" / "I hadn't noticed") but we get a lot more in other areas. Well worth adding to the collection. You can get it here.
