The Grimthorpe Grave

Summary

How do you save a witch who has been dead for centuries?

Alex and Asha of the A&A Detective Agency are on the case. Summer is over, and Asha and Alex haven't had a decent case in months. But just as a chill begins to stir the air, and the autumn leaves start to turn, Dr. Wright from the Fairfleet Institute comes to them with a cryptic note, signed by "The Witch of Waverly College," about Hannah Grimthorpe, the notorious witch from Northbrook's colonial past.

This is the perfect case to reinvigorate Alex and Asha's interest in keeping up the agency, but distractions come their way as school activities divide their attention. When more clues appear and Dr. Wright is forced out of the Institute, the two detectives decide they are going to need help from their classmates to solve the mystery.

With sneaky adults out to thwart the kids' mission, shadows lurking in corn mazes and cemeteries, and a Halloween deadline looming to uncover the truth about Hannah Grimthorpe, it's a race against time and a lesson in who to trust for the young detectives of Northbrook.
