A Man About the House

Salvatore poisoned Agnes to regain ownership of the villa, which had originally belonged to his family. He had already poisoned the sisters' uncle to inherit the estate, and marrying Agnes was part of his plan to legally secure control of the property. When his scheme began to unravel, he accelerated the poisoning to ensure he wouldn't lose what he had killed for.

Earlier, Ellen discovers a painting of Salvatore as Bacchus in her uncle's studio, hinting at his intimate connection to the estate and hinting at hidden motives.

Salvatore was slowly poisoning Agnes with arsenic, likely mixed into her food or drink. The poison caused her health to deteriorate gradually, mimicking a natural illness. Dr. Dench suspected arsenic poisoning after examining her symptoms and the villa's history.

The painting revealed Salvatore's celebrated status and intimate connection to the estate. It suggested that Salvatore had a much closer relationship with the sisters' uncle than initially apparent, hinting at hidden passions and motives beneath his charming exterior.

This discovery unsettled Ellen and planted seeds of doubt about Salvatore's true intentions toward the sisters.

Salvatore married Agnes because it gave him immediate legal control over the villa and estate. By marrying one of the owners, he could become the master of the property without raising suspicion. The marriage was a calculated move in his long-term plan to reclaim what his family had lost.

Ellen became suspicious when she noticed a change in Salvatore's behavior toward Agnes after their marriage. His charm gave way to a cooler, more controlling attitude. When Agnes's health began to deteriorate, Ellen's concerns intensified, leading her to believe Salvatore was harming her sister.

Salvatore killed the uncle because the villa had originally belonged to his family, and he had long been determined to regain ownership. He poisoned the uncle to inherit the estate, making the property available for him to claim through his subsequent marriage to Agnes.

The timeline reveals Salvatore had been employed by the uncle his entire life, giving him access and opportunity to carry out the poisoning.

Salvatore threw himself from the clifftop in despair rather than lose the property. When confronted by Dr. Dench and told to leave the country, Salvatore faced the collapse of his entire plan. Rather than give up the villa he had killed for, he chose death.

Agnes recovers and chooses to remain at the villa, determined to fulfill her late husband's wishes by tending the vineyard. Despite discovering Salvatore's attempt to kill her, she decides to stay and carry on the estate, maintaining the family legacy he had originally wanted.

Dr. Dench confronted Salvatore on the clifftop and warned him to leave the country, exposing the poisoning scheme. The confrontation represented the peak of tension as Salvatore's control over the estate began to crumble. Rather than flee, Salvatore chose to end his life.

Ellen enlisted Dr. Dench's help because he was Agnes's former fiancé and a trusted English doctor she could rely on. She needed his medical expertise to confirm her suspicion that Salvatore was poisoning Agnes and to help prove her case against him.

Ellen and Dr. Dench fell in love while working together to uncover Salvatore's poisoning scheme and protect Agnes. Their bond developed through shared danger and mutual purpose as they investigated the truth and tended to the sick Agnes.
