Reporter and amateur sleuth Joseph Rouletabille is sent to investigate a criminal case at the Château du Glandier and takes along his friend the lawyer Sainclair, who narrates. Mathilde Stangerson, the 30-something daughter of the castle's owner, Professor Joseph Stangerson, was found near-critically battered in a room adjacent to his laboratory on the castle grounds, with the door still locked from the inside.
