It was “Mystery Day” at the Front Porch Library. A “murder cake,” that dripped blood and had a knife sticking our of it was served. But best of all was the scavenger hunt which slipped in a lot of science (What does each of these machines do? What animal did these two skulls come from?) as well as clues that took the form of riddles and logic questions–and of course we threw in a snappy round of dodgeball.
