What is the author's style in Charley Skedaddle by Patricia Beatty?

The story is presented in third person from Charley's perspective. The limited point of view is acceptable to the story because the purpose is to take the reader through the events as Charley experiences them. In some stories of such limited perspective, the reader may have to decide whether the main character is slanting details to present himself in the best possible light. That doesn't seem to be the case in this story. Charley's shortcomings are presented with brutal honesty.
