This is a Roald Dahl story I hadn’t heard before, certainly much less-well-known than “James and the Giant Peach” or “Charlie and the Chocolate Factory”. It also doesn’t have the undercurrent of terror and threat of violence that most Dahl stories have.
Some animals have a window-washing business and a kid joins them.
The kids liked it and particularly enjoyed the audio cd performed by actor Richard E. Grant.
The audio runs 42:30.
