Lucy begins to waste away suspiciously. All her suitors fret, and Seward calls in his old teacher, Professor Abraham Van Helsing from Amsterdam. Van Helsing immediately determines the cause of Lucy's condition but refuses to disclose it, knowing that Seward's faith in him will be shaken if he starts to speak of vampires. Van Helsing tries multiple blood transfusions, but they are clearly losing ground. On a night when Van Helsing must return to Amsterdam (and his message to Seward asking him to watch the Westenra household is accidentally sent to the wrong address), Lucy and her mother are attacked by a wolf. Mrs Westenra, who has a heart condition, dies of fright, and Lucy apparently dies soon after.
Lucy is buried, but soon afterward the newspapers report children being stalked in the night by a "bloofer lady" (as they describe it), i.e. "beautiful lady".[2] Van Helsing, knowing that this means Lucy has become a vampire, confides in Seward, Lord Godalming and Morris. The suitors and Van Helsing track her down, and after a disturbing confrontation between her vampiric self and Arthur, they stake her heart, behead her, and fill her mouth with garlic
