Mailboat IV: The Shift in the Wind is a colorful read, filled with unique, likable caricatures and multiple subplots. This is a picturesque view of a small lakeside town with murderers hiding in the shadows. Bailey remains the focus of this story, but several subplots keep winding about, making this a wonderful read. As more questions are answered, the plot muddles deeper. Even though I keep scratching my head in puzzlement, I enjoyed this story that kept me guessing and wondering.
