Messiah was the codename for an intelligent robot, designed in Britain in the late 1930’s and built over the next twenty years. He was made of iron and steel, stood twelve feet tall and contained a powerful laser capable of destroying enemy fighter planes and tanks. Time passed, Armageddon never came and the project was mothballed. The lead scientist, now an old man, tells the stories to his grandson John who imagines Messiah as his robot companion. When John is fifteen, his grandfather dies and whispers to John; “find Messiah.”
The year is 2015 and John is thirty-five. War is again in the news. John decides to fulfill his grandfather’s last wish. His quest takes him to a village on the moors, where he finds Messiah just as war is breaking out. Using the secret code and key, he commands the robot to protect England and sets off to London, leaving Messiah to defend the country.
Along the way, John faces death several times and comes close to true love once. Finally the real reason for the war is revealed and his ultimate destiny plays out; he must use Messiah to save the world.
