Created by Gertrude Chandler Warner. These two stories are shorter and less complex than Warner's originals on which they're based. The format is approachable, with large font and occasional sketchlike illustrations, but the plots are slight; not even the child-friendly topics--the possibility that there's a vampire in the neighborhood and the disappearance of local dogs--can save them from mediocrity.

Gr 2-5 The four Alden children have a knack for finding mysteries wherever they go, and their dog's obedience class is no exception. When two dogs disappear from the class, suspicions abound. First, a man in the class is caught not telling the truth. Oddly, the teacher won't help look for the missing animals. Finally, there's the groomer, who happens to be present at each theft. The kids ask questions, take notes, and break down the list of suspects in a practiced, familiar style. Readers of the series should enjoy this addition.
