"Almost all kids love stories about dogs, and the Henry and Mudge series epitomizes most kid's fantasies about the perfect boy/dog relationship--they are wonderful friends, they understand each other, and they complement each other in all their adventures. In this story, Henry buys a spy kit, and he and Mudge learn how to be spies. Narrator George Guidall creates a young, enthusiastic voice for Henry, and a large, ponderous, slow voice for Mudge. Guidall reads this fun-filled adventure with humor, and maintains the same vocal inflections to create patterns and repetition, which in turn invite young listeners to participate. A great selection from this well-loved series for beginning readers. W.L.S. (c) AudioFile 2002, Portland, Maine"
