When strange, coded messages turn up in the chapel prayer box at Bellevue University, the minister suspects a recent campus death may have been murder, so he enlists the help of amateur sleuths Kathryn Frasier and Cece Goldman to decipher the codes and solve the mystery. But when a couple of young girls get wind of it, they decide to find the killer on their own. Almost everyone on campus has something to hide, and the story fluctuates between the rational search for the truth by the adults, and the occasionally misguided, but surprisingly perceptive, insight of the children.
