Murder on a Winter Afternoon: A completely addictive cozy mystery novel

I liked this book quite a bit. Melissa Craig decides to go on a writer's retreat and gets mixed up in a murder. The victim was the much disliked owner of the school hosting the retreat. There were a lot of twists and turns in the plot, but I had a hard time understanding why it took everyone in the book so long to figure out what was going on, when I already had it figured out. But I will admit that I was surprised by the final identity of the murderer at the end. I'm willing to read the next one by this author, but I wish that writers would really surprise me a little more often.
