This was a fun, light-hearted mystery that can easily be read in a day or two. Tj Jensen is a single parent to her two younger sisters, and is very involved in her small town community. The fall festival is underway when Tj finds the body of her good friend and local curmudgeon, Zachary. Zachary could count his friends on one hand but enjoyed spending time with Tj, telling her about his past and teaching her how to solve complex puzzles. She will rely on that knowledge to find out who killed Zachary while she juggles the fall festival, getting her sisters ready for Halloween, and her job. Very likeable characters and and I enjoyed the addition of the puzzles to the mystery.
