|Case Overview Index|
Bloodstains in the Festival is the fourteenth case featured in the Gosick series.
In the night of the festive event called Phantasmagoria, an unexpected murder occurs. Simon Hunt, a man who questions the credibility of supernatural abilities, dies in the middle of a performance with a dagger piercing his chest. The incident shakes the foundations of the festival and before any investigation can start, a chain of events cause the sinking of the Beelzebub's Skull into the waters of Lithuania.
With any traces of the crime now below the waves, Victorique de Blois and Kazuya Kujo can only rely on their own witness accounts to determine who killed Simon Hunt, and whether the case involves a darker issue than a mere clash of beliefs.
