It follows a retired couple who move to the countryside seeking peace, only to have their solitude shattered by a neighbor who begins visiting them every day at the exact same time—saying almost nothing and refusing to explain himself.

What starts as a minor annoyance slowly turns into a suffocating psychological ordeal, as the couple struggles to maintain politeness while their sense of control unravels. The novel is a dark, unsettling look at how far people will go to avoid confrontation—even at the cost of their own sanity.
