At this point, the reader is still not meant to know of Jekyll's dual identities, and the sense of mystery surrounding Jekyll and Hyde's relationship and Jekyll's reclusive behavior grows. Meanwhile, Utterson's world has become increasingly dark and horrifying, as Lanyon dies and Jekyll hides himself from the world. Through these events, Utterson's rational and logical world is slowly disintegrating into a world of confusion and mystery. Moreover, while the events of the novel become increasingly strange, the language and detail becomes increasingly sparse. This pattern first appears in an inability to describe the specific horror of Hyde's face, grows more powerful when Lanyon refuses to discuss the specifics of his horrific shock, and continues to develop in this chapter when Enfield and Utterson silently agree not to speak of Jekyll's apparent seizure and strange behavior. Thus, as the dramatic action continues to develop, the suspense and mystery surrounding Jekyll grows.
