The story opens on an Atlantic liner where Garrett Westenra, a dedicated and idealistic New York surgeon, encounters Valentine Valdana, a brilliant and eccentric journalist whose restless spirit contrasts sharply with his rigid ideals. Despite his initial aversion to her unconventional habits and unreserved nature, Westenra is stunned to recognize her as the woman who has haunted his dreams for years. Their mutual attraction defies logic, leading to a passionate marriage that quickly collides with the harsh realities of daily life and professional demands.
As they establish a private sanatorium in New York, the friction between Westenra's rigorous standards and Valentine's unpractical, vagabond nature begins to erode their relationship. Valentine struggles valiantly to adapt to the responsibilities of a professional man's wife, enduring overwhelming domestic burdens, but her lack of experience turns the venture into a financial and emotional strain. The arrival of Westenra's rebellious ward, Haidee, and the birth of their son, Bran, add new layers of complexity and tension to their already strained household.
Beneath the surface lies a deeper secret: Valentine's past. Believed to be a widow of a heroic soldier, she carries the heavy weight of a difficult previous marriage. When her first husband, Horace Valdana, unexpectedly reappears—alive and fleeing from his past—Valentine is forced into a web of deceit to protect her new family, especially her son, from devastating scandal and ruin. She tries desperately to shield Westenra from the truth, sacrificing her own peace and enduring cruel misunderstandings.
Westenra, consumed by his own severe nervous exhaustion and misinterpreting Valentine's growing coldness and distance as a lack of love, pulls away. The couple drifts into a painful estrangement, unable to bridge the gap created by unspoken truths and mutual exhaustion. When they finally part ways after a brief attempt at a fresh start in Jersey, the weight of the hidden reality breaks the remaining threads of their life together.
The narrative reaches its emotional climax when Valentine, pushed to her limits, reveals the truth to Westenra: her first husband never died. This revelation shatters the remaining foundations of their union, leaving both characters to face the profound desolation of their separated paths. Ultimately, the story is a profound examination of the heavy price of idealism, the sacrifices demanded by motherhood, and the tragic inevitability of unshared truths breaking even the strongest of loves.
