Summary: In the peculiar town of Bellwood, eleven-year-old Paul Marconi and his friends face a baffling mystery: hundreds of rubber duckies mysteriously appear on Mr. Babbage's lawn. As fires rage nearby and the annual Bratwurst Bonanza looms, the One and Onlys detective club must unravel the truth. With a list of suspects but no clear answers, Paul learns that not every mystery has a simple solution. Dive into a summer of friendship, sleuthing, and unexpected twists as Paul discovers that some puzzles are more than they seem.
