This work investigates the validity of various unexplained phenomena and psychic claims through a skeptical, scientific lens. Authors John Fairley and Simon Welfare, working alongside Arthur C. Clarke, examine historical accounts and contemporary reports of events ranging from telekinesis to spontaneous combustion. The text utilizes a journalistic framework to present these anomalies, contrasting anecdotal evidence with rigorous scientific inquiry to determine if any of these occurrences defy known physical laws.

The book is regarded as a balanced, accessible exploration of the paranormal that prioritizes rational explanation over sensationalism. Its approach reflects the analytical rigor associated with Arthur C. Clarke, making it a standard reference for those interested in the intersection of fringe science and critical thinking.
