When Van Helsing and Seward arrive the next morning, they are greeted by Mrs. Westenra, who tells them cheerfully that she removed all of the flowers from the room, including the wreath around Lucy's neck, and opened the window to let in fresh air. Once Mrs. Westenra has left the room, Van Helsing breaks downthe first time Seward has seen his old mentor lose control. Van Helsing regains his composure and the two men go into Lucy's room to find her horribly drained. This time, Van Helsing is the donor of the needed blood. He then warns Mrs. Westenra to never remove anything from the room, and he tells Dr. Seward that he himself will stay with Lucy for the next few nights. In her diary, Lucy reports feeling much better, even though she can hear the sound of something flapping angrily outside of her window.
The September 18th article in the Pall Mall Gazette reports that a large wolf has escaped from its cage and returned the next day, its head covered by broken glass.
Back at the asylum and awaiting word from Van Helsing, Seward is working in his office when he is attacked by Renfield. The lunatic bursts in and attacks him with a knife, cutting his wrist. Seward knocks him back with a punch, and at that point Renfield seems to lose interest in him. As the attendants rush in, Renfield is busying himself licking up the small pool of Seward's blood on the floor. Meanwhile, Van Helsing sends a telegram telling Seward to go to Hillingham and spend the night watching Lucy, as the older doctor needs to spend a day in Amsterdam. The telegram is delayed by a day, so Seward does not get the instructions on time.
Lucy has trouble sleeping, and her mother comes in to lie with her in bed. Suddenly, a wolf uses its head to smash through the window; only the animal's head breaks through the glass. Lucy's mother thrashes around fearfully, accidentally tearing away Lucy's garlic wreath. The old woman has a fatal heart attack. The wolf then withdraws its head and disappears, and Lucy loses consciousness. When she comes to, the four maids of the house come in. Terrified, they wrap Mrs. Westenra's body in a sheet and lay it on the bed. Lucy orders them to go to the kitchen and have a glass of wine to calm their nerves. She also lays all of the garlic flowers on her mother's body. When the maids don't come back, Lucy goes to the kitchen to find the four women unconscious; the wine smells like the drug laudanum. Lucy writes that the "air seems full of specks, floating and circling," and finishes her entry fearful that she will not survive the night.
