A Christmas Mystery. Green Valley, #5

When I return to my hometown for Christmas, I have only two goals. Spend time with my family and discover the identity of my mystery pen pal. I'm not interested in holiday festivities or reconnecting with old acquaintances, specifically grumpy, infuriating Theo HumphreyFor the past two years, I've been traveling the country in my tiny house, building a substantial social media following and recovering from the death of my fiancé, who died three weeks before our wedding day.
Now I'm feeling more myself, and I want to find out who has been writing me anonymously for more than a year. Our online correspondence has become one of the best things in my life, and I'm determined to follow the clues to unravel this mystery. My plans keep getting disturbed by Theo. He was the best friend of my former fiancé, but he's never liked me. He always thought I was too frivolous and superficial to be a good match for his friend.  Now he's always around, glowering and muttering sarcastic comments and generally making a nuisance of himself.
My priority should be revealing my secret pen pal, but instead all I can think about is Theo.
