Someone is stealing trash from a recycling plant, which sounds ridiculous until the clues start lining up.
Geronimo and Hercule take the seventy-ninth investigation seriously enough to solve it, and the environmental thread runs through the story without turning into a lesson. Cooperation, curiosity and a fair amount of comic indignity get them to the answer, which stays hidden until the closing pages.
Summing it up:
• A theft at a recycling plant that turns out to be worth solving
• Hercule and Geronimo working the case as an odd pair
• Environmental awareness raised inside the plot, not bolted on
• Brief chapters and clear print for developing readers
