Alice being unable to leave the library due to agoraphobia admits to Snoo and Dr Cadogan that she is the one who has been sleeping in the library, and Snoo begins to wonder if she has wasted her money and gets into an argument with a competing ice cream seller when he accuses her of being on his pitch.

Simon resorts to banning him from the library, which leads Alice and Snoo setting about supplying Dr Cadogan books from her father's mansion, by way of a tunnel Alice has dug from the library. Simon meanwhile has to deal with various friends of Dr Cadogan trying to get a supply of spong that they crave.
