After seeing a magician perform, Benny enlists his dog Watch to help him put on his own magic show, but then both Watch and Benny's magic bag disappear.

When Benny Alden decides he wants to go into business like his grandfather, his first several attempts don't quite work out.

The Aldens discover that one of Pikesville's little league coaches has been cheating all season, which is somehow related to a plan to raze the town's historic baseball field.

The Alden children uncover a plot to sabotage the Greenfield Bears baseball team. Includes baseball puzzles and activities.

The Aldens are thrilled to be helping out at Cogwheel Stadium as the Clayton Cogs try to win the pennant, but when the children realize someone has stolen the team's pitching signals and given them to the other team, they set out to find the spy before he ruins the team's chance at victory.
