Summary: At Saint-Sulpice, Sister Sandrine manages to call three of the four numbers on her list, only to learn that all three contacts are dead. The fourth number yields only an answering machine, on which Sister Sandrine is leaving a frightened, panicked message when Silas finds and kills her.
Analysis: Although Sister Sandrine does not know the identify of her contacts, readers can presume that the person she is trying to call when she is killed—“the number she was not supposed to call unless the first three [on her list] could not be reached” (p. 145)—is Saunière. Silas has now realized how he has been tricked, and Sister Sandrine pays the price—although not before delivering a parting shot at Opus Dei: “Jesus had but one true message… I cannot see that message in Opus Dei” (p. 146). Both Silas and Sister Sandrine believe they are serving God and the church; yet Silas’ “service” may call to mind Jesus’ own words about how those who served him could be recognized: “Ye shall know them by their fruits” (Matt. 7:16, KJV).
