Gosick takes place in 1924 in a small, French-speaking fictional European country; which stretches from Switzerland, through the Alps between France and Italy, to the Mediterranean Sea. The country is called "Sauville" (ソヴュール王国, sovyūru ōkoku) in the light novels and "Saubureme" (ソヴレム, sovureme) is Sauville's capital in the anime adaption. The story centers on Kazuya Kujo, the third son of a high-ranking officer of the Imperial Japanese Army, who is a transfer student to St. Marguerite Academy, where urban legends and horror stories are popular. There he meets Victorique de Blois, a mysterious yet beautiful and brilliant girl who never comes to class and spends her days reading the entire contents of the library or solving mysteries that even detectives can not solve. The early episodes mostly focus on Kazuya and Victorique getting involved in different criminal cases and their struggle to solve them, at the same time forming important bonds with different people and each other. However, as the series advances, the tenebrous background of Victorique and her family comes back to haunt her.
