Book 105 of the Boxcar Children series. This fun mystery has a great twist, weird puzzle, and happy ending even if a bit silly in the end. Aside from that I love the spirit of these books showing a willingness to pitch in where needed. The lessons on attitude I feel is lost on a lot of the younger children. The idea of hardworking being its own reward. Spend time with these and you will get a sense of the old virtues we’ve stepped away from. I recommend this one and the whole series.
