The A&a Detective Agency: The Grimthorpe Grave

Alex and Asha's interest in keeping up the agency is waning, but distractions come their way as school obligations divide their attention. When their mentor, Dr. Wright brings them an intriguing clue signed by "the Witch of Waverly College," they jump at the chance to solve the mystery of who wrote it. But when more clues gather, the two detectives decide they are going to need help to solve the case, so they enlist a few peers as consultants. But the President of Waverly College is out to thwart the kids' mission to uncover the truth about the Northbrook witch trials. It's a race against time and a lesson in who to trust for the young detectives.
