Iolanta Gazenkampf works at the auditing chamber of Frayeburg. During the annual inspection she discovers that the much-loved and famous owner of all the vineyards in the kingdom has been filing incorrect declarations for many years. She decides to look into the matter personally and finds herself caught up in intrigue between noble houses of the kingdom, a local order, and the Company—an organization of the neighboring principality of Moroz. She must, with a single pen stroke, preserve the reputation of the hereditary winemaker Roland von Richgoffen and try not to die herself.
