Quantum Menace

Jack is an eccentric person. He is a cryptologist the best alive and this might allow for his eccentricity - in his youth Jack had single-handedly broken the Enigma code in fifteen minutes. This might also have allowed for the alien species trying to contact him with a slightly more difficult mission: humanity has several months to decipher a mathematical code locked in the long-gone-dust brain of a child dead several centuries ago. Oh and he might have to volunteer to travel into the sun. Jack’s plans for action include a variety of strange human specimens some world leaders and a load of... cat shit. At stake - the world the aliens the entire solar system. Maybe the universe?
