Dracula is composed as a collection of journal entries, letters, telegrams, and memos. The idea, Stoker tells us in the note at the beginning of the novel, is to present the events of the story "as simple fact," even though some of the events are hard to believe. The collection of documents is like a stack of evidence being presented at court. That's right – as the reader, you get to act as judge and jury. The writing style is straightforward and very immediate – the characters write in their journals practically as events are happening, so we experience the events almost as the characters do. Exciting!
