Written in the late 19th century, "Count Magnus" is M. R. James's masterwork of understated supernatural dread, presenting itself as an editor's compilation of travel notes and journals left by a Mr. Wraxall. The story follows an antiquarian's fatal curiosity as he researches a powerful Swedish nobleman while lodging near an ancient manor house, only to discover disturbing legends and mysterious texts hinting at dark practices. What begins as scholarly fascination becomes a descent into inexplicable terror that pursues Wraxall across Europe and to his mysterious death.
