Books with title Unusual Suspects

In book two of the series, the Sisters Grimm start school at Ferryport Landing Elementary. Daphne’s lucky enough to get Snow White for a teacher—she loves little people—but poor Sabrina’s stuck with Mr. Grumpner and a class of mildly psychotic sixth graders. When Mr. Grumpner is found hanging in a spider’s web, it is up to the Grimms to find the Everafter who did it. If only Sabrina can get over her distrust of all fairy-tale folk. But how can she trust those who just might be responsible for the disappearance of her parents?
