Summary
Analysis
Still flying to France, Aringarosa hangs up with Fache for a second time. His and Silas’s plan has gone horribly wrong. The bishop asks the pilot to change his destination to London, but the man laughs him off. He refuses Aringarosa’s bribe of a ten-thousand-euro Vatican bond but asks for his amethyst ring. Feeling this token of his bishophood will soon be meaningless, Aringarosa hands it over. The pilot changes course, but Aringarosa still feels his holy purpose crumbling around him.
The novel withholds the content of Aringarosa’s conversations with Fache, allowing for further speculation that the captain is the Teacher who planned Silas’s murder spree. Presumably, Aringarosa is panicking because Silas hasn’t yet retrieved the keystone. That said, he seems more ashamed than that circumstance would warrant, suggesting something about the situation has shaken his belief in his own “holy purpose.”
