Little Did Ken and his buddies -- Orv, Horseshoes, and Bo -- know just how exciting their summer was about to become. Who would ever have pictured their joining forces with the good guys, Mongoose, in a heroic attempt to foil Cobra's latest nefarious plot? It is not long before V.A.C.U.U.M. (Volunteer Agents Crusading Unsteadily Under Mongoose) is officially born. Add one "Beautiful Assistant Gangbuster," Mary Evans (full title, V.A.C.U.U.M. B.A.G.), a modest fleet of vintage cars and a World War I De Havilland and the fun is about to begin. Book jacket.
