The Lilac Girl (Romance Classic). Ralph Henry Barbour

Wade Herrick and his business partner Ed are prospectors looking for gold in Colorado. One day, as they wait between the claims, a train stops in the station and Wade notices a beautiful young lady on it. He approaches to meet her and after a pleasant conversation he expresses his affections to her and swears on eternal love to her under the moonlight. She laughingly gives him a sprig of her lilacs as a love-token, and he promises to keep it forever and to find her one day. Years pass and Wade's partner Ed dies, leaving his property and belongings to Wade, including a house in New Hampshire. When Wade shows up to his new house he is in for a shocking surprise, his next door neighbor as a lilac girl from the train.
