The Mudshark Detective Agency is on the case in a winning tale from Gary Paulsen, about whom Booklist writes in a starred review, "When it comes to telling funny stories about boys, no one surpasses Paulsen." Mudshark is cool. He's fast-thinking and fast-moving, and with his photographic memory, he's the go-to guy with the answers. Lost your shoe? Your dad's car? Can't find your homework? Ask Mudshark. At least, until the Psychic Parrot takes up residence in the school library. The word in school is that the parrot can out-think Mudshark. And right now, the school needs someone who's good at solving problems. There's an escaped gerbil running the halls, a near-nuclear emergency in the faculty restroom, and an unexplained phenomenon involving disappearing erasers. Once Mudshark solves the mystery of the erasers, he plans to investigate the Psychic Parrot. . . . In Mudshark, Paulsen introduces readers to a resourceful boy who will have kids everywhere thinking, and laughing.
