Church. At the start of the novel, we find Roger, a young English gentleman, being summoned by Pope Innocent XI to serve in a diplomatic capacity at the English court. Having spent two years as a novice in a monastery, he questions his vocation but is eager to serve God in the world rather than in the cloister. The scene shifts as he arrives in London after a seven-year absence, describing the city’s transformation since the Great Fire. Introduced to a host of characters, including his boisterous cousin Tom Jermyn and the enigmatic Cousin Dorothy, Roger's arrival marks the beginning of his involvement in the political intrigues and cultural dynamics of a court influenced by religious struggles, complex alliances, and his own personal desires.
