Myra Stevenson, an Anglo Indian teacher and single mother to Thomas, faces her worst nightmare when she discovers Thomas's father has visited him without her knowledge. As he belongs to the echelons of British society in India, she fears he will claim their son who looks European.

Giles Cottrell, owner of a tea plantation and an officer in the Indian Army reserves, had no idea he fathered a son until his grandmother (Jessie) informed him of the fact in a letter after her death. He informs Myra that his grandmother left them each a letter. His letter sets out directives, one being that they must marry for Thomas to bear his name in accordance to the Legitimacy Act, 1926.

Myra refuses to allow Giles to read her letter. Conflicts arise between the pair as a result, especially as Jessie left her property in Delhi to Myra. The couple marry and embark on a train journey to Darjeeling to await the decree that makes Thomas legally a Cottrell. However, their married life is fraught with issues of mistrust and outside interferences. Myra once again faces her past fears of ostracism. How she wins her husband's love and stands tall amidst racial misconceptions and discrimination is the story she relates.
