Mina is getting very worried, as she has not received any news from Jonathan for a long time. Then there is a very violent storm and a ship arrives at Exeter with no live passengers on board save a mad dog but with all the cargo intact. Mina’s friend Lucy comes to live with her and Mina discovers that she has a tendency to sleepwalk and on a couple of occasions rescues her when she has walked to the pier in her sleep. Lucy starts to mumble strange things in her sleep and Mina notices that she has begun to look very weak and pale of late.

Some days later Mina receives a letter informing her that Jonathan is alive but is suffering from brain fever. He is in a hospital in Budapest. and keeps ranting and raving about strange things like wolves and blood. Mina departs for Budapest to nurse him back to health and they are married in the hospital itself. Jonathan Harker gives her his sealed journal where he has written all about his experiences in the castle. Mina wows that she would never open it unless it was for his safety.

Dr. Seward observes that his patient is behaving even more weirdly and tends to get very violent in the daytime and calm at night. He escapes once but is caught and brought back. Lucy is getting weaker by the day and her fiancée Arthur Holmwood requests Dr. Seward to have a look at her. Dr. Seward cannot find anything wrong with her except that she indeed does look very pale and bloodless. He writes to his dear friend Van Helsing to come and offer his valuable advice, as he is an expert on obscure diseases.
