Lucy Westenra began to walk in her sleep. Her friend Mina found her one night in the churchyard above the sea, lying on their favourite seat with something dark bending over her. When Mina came near, the thing was gone, and Lucy was alone, breathing hard, with two little red marks on her throat. After that night Lucy grew pale and weak. She slept badly, she dreamed of red eyes, and every morning the marks were larger. Her doctor, John Seward, could find no illness and no loss of blood anywhere, and yet the blood was going. He wrote to his old teacher in Amsterdam, Professor Van Helsing, who came at once. The old professor looked at Lucy for a long time and said nothing. Then he gave her his own blood, and afterwards the blood of three other men, and each time she came back to life for a day. He filled her room with garlic flowers, and while the flowers were there she was safe.
