Synopsis

The Doctor and Donna enter an abandoned library. Not just any old library - it's the greatest in the universe. The one that was sealed off a century before, without any explanation - unless you include the cryptic warning "Count the shadows". With the shadows on the move again, the Doctor and Donna must uncover the terrible truth behind the Nodes and the Data Ghost to reveal the library's secret.
