A Puzzle for Percy

Plot
Percy is given a very important job, but he isn't told what it is. With his trucks, he collects telegraph poles from the Timber Yard, car tyres and rope from the Dump, and sand from the Sand Works. Then, Percy takes them to a secret location, and that night, Gordon teases Percy that the Fat Controller was making sure that he was very busy. A few weeks later, Percy is invited to the secret location which turns out to be a new children's playground.
