After the young boy Philip is orphaned, he is adopted by his older cousin Ambrose, who raises him as a son on his large estate in Cornwall. Despite societal beliefs of the necessity of motherhood, Philip grows up with a nearly complete absence of women in the household, before Ambrose leaves the estate for the sunnier climate of Florence. A young man, Philip is left with his godfather Nick Kendall, and learns through correspondence that Ambrose has met his widowed cousin Rachel in Florence, and they have wed. The Kendalls express surprise that Ambrose has become interested in women, though Philip found the absence of female companionship natural. Later, Ambrose begins sending letters indicating distrust of the medical care he is receiving in Florence. Concerned, Philip travels to Italy, only to be informed Ambrose has died and Rachel has left. Though Ambrose's will left the entire estate to Philip pending his next birthday, Philip is convinced Rachel is guilty of murder and threatens her friend Rinaldi with revenge..
