Now Miss Stafford feels compelled to hunt for the recipient and/or the original author. A mystery has diverted her attention from her loneliness and presents new avenues of hope, just in time for Christmas! But what has she set in motion, and what will come of it? A lighthearted story with a hint of romance. (Summary by TriciaG)
