Plot

In the 1830s, a young orphan named Philip 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 to pursue better health. Now a young man, Philip is left in the care of his godfather Nick Kendall, and learns through correspondence that Ambrose has wed their widowed, distant cousin Rachel in Florence. 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 25th birthday, Philip is convinced Rachel is guilty of murder and threatens her friend Rainaldi with revenge.
