The Nineteen Questions of the Torturer is a work written by Praetorius of Verditius in 841, dealing with the efficient extraction of information from a subject's mind, using magical means. It offers advice on this topic in counterpoint to a discussion of the methods by which a mundane interrogator might extract similar information. Like most of Praetorius' other works, this is not for the faint of heart.
