This time, Uncle Vernon goes crazy. He goes halfway into the forest and drives out again. He does the same with a bridge and a parking lot.
"Daddy's gone mad, hasn't he?" Dudley says with fear on his face.
Finally, he drives to the coast. Uncle Vernon is giggling. "I found it! No bloody postman will be able to get within a mile of this."
He points to a small island that has a shack on it. It is storming outside furiously and the waves look dangerous.
