George decides to go camping with her dog, Timmy, so he can recover from an ear injury without being mocked for wearing a large cardboard collar that prevents him from scratching his wound.

The girls then go to George's parents' house for more food supplies and are informed that Julian and Dick will be arriving in a day or two.

That night, while sleeping in the old cottage they hear weeping and wailing noises and see some kind of light that makes them a bit afraid.

Afterwards, Uncle Quentin reveals that it was a secret document which has only two copies in the world, one with himself and the other with Sir James Lawton-Harrison (which has been stolen).

At last, it was shown that Timmy was scratching the wound on his ear making it go bad again, and he would have to wear the cardboard collar again, just as the story began with.
