A newly-formed Friulian Committee is firmly convinced that Shakespeare drew inspiration from the Trevisan marquises, da Camino, in the Middle Ages, to write one of his most famous tragedies, Hamlet. An apparent research supports this approach. That is why Guglielmo, a middle-aged Italian teacher, is called out to speak in person with Mr Brough, the medievalist author of the thesis, to meet his confirmation. He will be involved in a one-day, intricate mission down the narrow alleyways and glittering palaces of a midsummer London. Will Guglielmo succeed in his quest for the truth?
