Caius Zip, the young time traveller, arrives at Paris in 1905. The turn of the 20th century is a period that sizzles with ideas and realizations, and the universe is about to be contemplated as it never was before. In this work of fiction, Einstein was resting in Paris before his innovating Theory of Relativity enlightened him. At that same time, Picasso was just starting on his idea of breaking with conventional perspective. Both characters seek the same concept: space-time relation. The encounter between art and science is finally possible by means of a limitless imagination. Caius penetrates the birth of the Theory of Relativity and cubism, and also manages to solve a murder mystery with the help of his two young friends, Agatha Christie, with her investigative mind, and Charlie Chaplin, who provides a touch of magic to this surprising work of fiction.
