A metaphysical crisis occurs when the note C sharp mysteriously vanishes after being played perfectly by the pianist Jonathan Blenheim. The absence causes tonal collapse worldwide, leading to chaos in orchestras and triggering a bureaucratic panic at the Bureau of Eclectic Notation (BEN). The Bureau attempts to force the note D Flat into substitution, to be met with fierce opposition by D Flat. The narrative follows the adventures of the missing C sharp, which has been transposed into the viscosity of frying grease within Wotof Wongip's chip shop, becoming a sentient sound that seeks resolution through "e;grease-touch"e; and memory. Ultimately, characters including Detective Fiddlefaddle, the Fryer Prophet Frank, and the adverbial entity Softly work to resolve the harmonic viscosity. Eventually the note is facilitated to make an imperfect, merciful return, and the crisis between pitch and substance is finally resolved.
