The Blue Walls of Heaven: Error Message Adam Stone hears voices. After investigating, he discovers their source: a hyper-intelligent computer network inhabiting the Owl Nebula, one thousand light-years from Earth. This alien life-form has chosen Adam to be the sole recipient of its plan to save Mankind from itself by adjusting the universal constants of physics, thereby eliminating Man's self-destructive instincts. Unfortunately they need to analyse a large sample of Russian jokes in order to understand man's irrational nature. Adam has been chosen to help them in their bizarre quest - despite his being hopeless at communicating, paranoid, penniless, emotionally unstable, over-dependent on his fragile relationships with women, and obsessed with a young woman who he kills and is subsequently haunted by. While attempting to evade the police, Adam enters an underground labyrinth below his flat which has some uncanny properties: time and space become an infinite loop, which eventually results in an astonishing conclusion to Adam's journey of self-discovery.
