A robot,designed by Leonardo but recreated by Piero as a fire-breathing demon,is on the loose in Florence until Piero,who has orchestrated its retreat, is declared a hero and asked to take over power from the duke. At last Leonardo appreciates that this is the culmination of Piero's theft of his note-book as a means to rule Florence. Accordingly he makes sure that during the 'demon's' next outing Piero is discredited and the duke reinstated . This however alienates him from dim Lorenzo,who cannot see his father's villainy.
