The death sentence of a spaceman: the claustrophobic editor of a newspaper's letters page receives a note from a kidnapper informing him that 'intolerance will not be tolerated' and that a hostage will be executed unless he arranges for a letter to be published on the front page of the next morning's paper.
So begins the narrator's tale, within which we encounter strange characters such as Chris The Crossword Compiler and Mark Twain (or at least, his namesake) and hear of an enigmatic organisation of moral vigilantes called The Amino. But who is the kidnapper? What are his/her motives? And why would he/she wish to pass a death sentence on the narrator?
