Dracula's Guest" follows an unnamed Englishman traveller as he wanders around Munich before leaving for Transylvania. It is Walpurgis Night and the young Englishman foolishly leaves his hotel, in spite of the coachman's warnings, and wanders through a dense forest alone. Along the way, he feels that he is being watched by a tall and thin stranger (possibly Count Dracula).
The short story climaxes in an old graveyard, where the Englishman encounters a sleeping female vampire called Countess Dolingen in a marble tomb with a large iron stake driven into it. This malevolent and beautiful vampire awakens from her marble bier to conjure a snowstorm before being struck by lightning and returning to her eternal prison. However, the Englishman's troubles are not quite over, as he is dragged away by an unseen force and rendered unconscious. He awakens to find a "gigantic" wolf lying on his chest and licking at his throat; however, the wolf merely keeps him warm and protects him until help arrives.
When the Englishman is finally taken back to his hotel, a telegram awaits him from his expectant host Dracula, with a warning about "dangers from snow and wolves and night".
