After dinner, Hermione walked to the door of the study room and pointed her wand at it. There were multiple protecting spells on it. A simple Alohomora wouldn’t do the job here. Even if she managed to open the door with magic force, it would immediately signal to Marcus. Hermione would have to deactivate the spells one by one before entering. There was too little time, it was already eleven. Marcus could return any minute. Who knew how long it would take to break all the spells and Hermione would still need some time to explore the room and activate the spells back on her way out.
