While traveling on the Continent, Crawford is called upon to assist another Englishman who is suffering from a seizure. The man is Percy Shelley, and is accompanied by Lord Byron, John Polidori, and Claire Clarmont. Byron and Shelley are also connected to the nephilim, which they see as both a blessing and a curse. The nephilim can prolong the lives of humans and serve as muses who help to inspire great works of creativity, but they are extremely jealous and will destroy anyone they see as a rival. Crawford and the two poets make their way up the Jungfrau, where it is said one might be able to break the bond with a nephilim. After answering a version of the Riddle of the Sphinx Crawford manages to free himself from his wife. In doing so he also learns more about the nature of the nephilim.
