An innocent letter is only dangerous when it falls into the wrong hands.
Louisa Rosemeyer is a lady with no money, no parents, and, regrettably, no husband. Left with no place to go, she writes a letter to her aunt, Mrs. Irwin, asking for an invitation to live with her. Ever cautious and optimistic, Louisa hopes the trip will bring the new beginning she has been searching for.
After being forced out of his childhood home, Jack Warwick lets Mrs. Irwin's house, happy to be away from his family and their many squabbles. Haunted by his past, he drowns his loneliness in drink, and with it, his better judgment. When a letter arrives at his new house, addressed to the previous occupant, Mrs. Irwin, from her niece, Jack writes an incoherent reply, inviting the young lady to come stay…an event which his drinking causes him to forget.
When the chaos surrounding Louisa’s untimely arrival at Jack’s house causes a scandal, there is only one way to mend her reputation: Marriage. As Jack’s feelings for Louisa grow, he realizes there is only one way to mend himself: To be loved by Louisa. Devastated to be married to a near stranger, and a scoundrel at that, Louisa closes off her heart. She has always planned to marry for love. But she quickly learns that love has plans of its own.
