Gareth St. Clair always understood that his father hated him, but to deprive a son who had done nothing wrong of his inheritance?! There must be some good reason for this! The young aristocrat has every reason to believe that the answer to the family secret lies in some mysterious old diary. The only problem is that it’s written in Italian!

You have to call for help from Hyacinth Bridgerton, the owner of the sharpest tongue in London society and a young lady with whom, in Gareth’s opinion, only a saint can endure communication. But she knows Italian very well... well, at least she pretends that she does.

So begins the amazing story of the incredibly funny adventures of Gareth and Hyacinth, who have to understand that the path to happiness does not lie in old family secrets and not in knowledge of foreign languages, but simply in true love.
