The lonely house

In Short

This atmospheric thriller follows Lily Fairfield, a guileless young Englishwoman, as she travels to Monaco to stay with her aunt and uncle at the isolated villa, La Solitude. Expecting a peaceful retreat, Lily instead discovers a household steeped in secrecy, poverty, and an unsettling preoccupation with money. As bodies begin to appear in the vicinity, Lily must navigate the dangerous intentions of her hosts and the charming, yet suspicious, behavior of their son. A classic example of early 20th-century suspense, the book endures through its vivid setting and the creeping dread that transforms a simple family visit into a fight for survival.

The Story

Lily Fairfield, an unsophisticated and optimistic survivor of the Great War, arrives in Monte Carlo to stay with her aunt and uncle, the Count and Countess Polda. The couple lives in an isolated, gloomy house called La Solitude, where the atmosphere is immediately tense. Lily is surprised to find her aunt is frequently short of money and fixated on the financial benefits Lily’s presence might provide. The house is serviced by a pale, terrified maid named Cristina, and the overall mood is one of decay and hidden peril.

Soon after her arrival, Lily learns of a mysterious death involving a wealthy visitor. Despite the Countess’s attempts to isolate her niece, Lily encounters a middle-aged French observer, Hercules Popeau, and a young British officer, Angus Stuart. These men quickly perceive that Lily is in danger. Tensions rise as the Countess and her son, the dandyish Beppo, attempt to manipulate Lily, clearly hoping to tie her to their family through marriage. Lily, though naive, begins to notice discrepancies: the villa’s gate is left unlocked at night, and she hears unsettling movements in the yard.

As the plot progresses, it becomes clear that the Poldas are involved in a series of predatory crimes. The "eccentric" disappearance of a wealthy guest is revealed to be a murder, with the body discovered near the villa. While Beppo tries to charm Lily and distract her from the truth, the investigative efforts of Popeau and his associates begin to close in on the Poldas. The narrative tension reaches a breaking point when Lily realizes her hosts are not merely eccentric, but dangerous opportunists willing to exploit her for their own gain.

In the final movement, the truth about the Poldas’ criminal activities—which include robbery and potential murder—is uncovered. With the help of the vigilant Popeau, who orchestrates a clever intervention, Lily is rescued from the suffocating influence of her relatives. The story concludes with the wedding of Lily and Angus Stuart. In a final, dark note, Popeau reveals his intent to see the Countess face justice for her crimes, ensuring that the sinister atmosphere of La Solitude is finally dispelled by the arrival of the law.

The People

Lily Fairfield is the story’s moral center, a young woman whose "simple natured" optimism makes her vulnerable to the predatory world of the Poldas. Her journey is one of awakening; she moves from trusting innocence to a sharp realization of the danger surrounding her.

The Countess Polda is a study in calculated malice. Driven by a desperate need for money and a lack of empathy, she treats Lily as a resource to be exploited rather than a niece to be cherished. She remains the primary antagonist, maintaining a veneer of aristocratic dignity that masks her involvement in criminal activity.

Hercules Popeau is the quintessential watchful outsider. As a man of experience and high intelligence, he functions as the story’s detective, using his wit and social maneuvering to protect Lily and dismantle the Poldas’ web of lies.

Angus Stuart, the romantic lead, serves as a protector who must overcome his initial prejudices to save Lily. His love for her provides the emotional drive that eventually leads to their escape from the oppressive influence of La Solitude.

In Its Own Voice

The narrative establishes Lily’s initial, dreamlike sense of vulnerability:

“With dreadful suddenness, out of the dark void above there leapt on her a huge black and white cat.”

The true nature of her hosts is revealed through their cold-blooded discussions overheard by their niece:

“Remember that we are receiving with her a hundred and twenty-five francs a week. If she is not satisfied she will go. Also, as the Count said only the other day, she may be useful to us in other ways.”

The weight of the danger surrounding Lily is captured in a warning from the observant Mr. Popeau:

“I regard her as being in real danger of having her life wrecked by a number of cruel, selfish, and unscrupulous people, who care for her as much as I do for that piece of paper on the floor!”

What It's Really About

At its heart, the book explores the tension between the outward elegance of the Riviera and the moral rot that can hide beneath a polished surface. It questions the safety of traditional social hierarchies, showing how aristocrats, when pushed by poverty and greed, can become predators. The narrative also examines the "innocence" of the post-war generation, contrasting Lily’s sincere, old-fashioned values with the cynical, mercenary world of her hosts. Ultimately, it is an argument for vigilance, suggesting that even in the most beautiful settings, one must be prepared to see the shadows for what they are rather than what one wishes them to be.

Why Read It Today

Readers who enjoy the slow-burn suspense of early 20th-century thrillers will find much to admire here. The book captures a specific, glittering, and slightly sinister version of the French Riviera that feels both authentic and haunting. The prose is elegant and measured, focusing on the internal shift of a young woman coming to terms with the reality of evil.

Those unfamiliar with the period may find the social customs and the "old-fashioned" language somewhat formal, reflecting the post-WWI era's rigid class structures. However, these elements add to the book’s historical flavor rather than distracting from the plot. Lily’s transition from a girl who takes things at face value to one who recognizes the necessity of caution is satisfyingly rendered, and Hercules Popeau remains a memorable, wily protagonist. The book is not a fast-paced action thriller but rather a psychological study of entrapment and release. It stays with you because of the eerie, isolated feeling of La Solitude and the quiet, persistent kindness of the man who ultimately orchestrates the escape. If you appreciate a story that balances character study with a genuine, creeping sense of dread, you will find this a rewarding and atmospheric experience.
