October 1493,
the height of the Renaissance.In a
rapidly changing world, Milan flourishes under the leadership of Ludovico il
Moro.Those wandering the courtyards of
the city's castle often encounter a man in his forties dressed in long pink
robes, lost in his own thoughts. The man lives above his workshop, with his
mother and a mischievous little boy whom he dotes on; he doesn't eat meat,
writes from right to left, and struggles to get paid by his employers. His name
is Leonardo da Vinci. His fame extends beyond the Alps, to the French court of
Charles VIII, whose envoys have been tasked with a secret mission that concerns
Leonardo himself, and his most daring designs.

When a man is found dead in the Castle's courtyard, il Moro turns to Da Vinci
for help. Though the corpse shows no signs of violence, the death is highly
suspicious: rumours of a plague or superstitious explanations need to be
disproven quickly. Leonardo is in no position to refuse his master's request to
investigate.
