Lucy begins a diary, in which she records bad dreams and recounts that something scratches at her window in the night. Concerned that Lucy has become pale and weak again, Arthur Holmwood writes to Dr. Seward, asking him to examine her. Seward does so, and reports that Lucy’s illness is beyond his experience. He sends for his former teacher, the celebrated Professor Van Helsing of Amsterdam, to examine the girl. Van Helsing arrives, observes Lucy, and then returns home briefly, asking to be kept abreast of Lucy’s condition by telegram. He tells Seward that he cannot ascertain the cause of Lucy’s illness, but concurs that much of her blood has been lost.
