Professor Dunning is in lockdown. He's trapped in his university rooms with just Digby, his dog, and Mr Wilson, a cricket ball with a face drawn on in biro, for company. Dunning's well-equipped for a spell in confinement. He has port to drink, Mr Wilson to talk to and the new volume of Pedagogical Grammars Before the Eighteenth Century to read. Besides, Harry Crow will be along soon to rescue him... But as the days pass, Dunning's sanity and hopes of rescue start to ebb away. Will his port reserves run dry? Is Mr Wilson laughing at him? And who, or what, is Dunning actually hiding from?
