The narrative centers on a small, disabled city boy devoted to a tiny white dog and supported by street acquaintances until a newspaper notice seeking information about him creates alarm and forces action. The plot moves from urban scenes to rural surroundings under the care of a caring aunt, includes a hurried flight and an ensuing accident, and concludes with recovery and brighter prospects. Throughout, the work examines loyalty, the precariousness of childhood alone in the city, and the protective bonds between child, guardian, and pet.
