In this excerpt from "The Red Pyramid" by Rick Riordan, Sadie is sharing an intriguing story filled with unusual details, such as glowing letters and a serpent staff. As she recounts these oddities, Inspector Williams shows disbelief, which is evident through his raised eyebrow. His reaction suggests that he views Sadie's tale as a product of an overactive imagination rather than reality.

Sadie, however, insists on her honesty, playfully pointing out the Inspector's rising eyebrow, suggesting that he is struggling to accept her words. This interaction highlights a blend of humor and tension as Sadie attempts to convince the skeptical Inspector of the truth behind her extraordinary experiences.
