When a hotel owner is forced to sell under mysterious circumstances, Freddy and his friend Mr. Camphor pose as campers to investigate.

Mischievously, Camphor pokes holes in Freddy’s cover story about studying with a witch doctor: There is a gunshot from the hotel.

Freddy returns to spy on the hotel, and overhears Simon plotting with Eha.

Mr. Bean is at Camphor’s estate: to general surprise he is adeptly flattering Aunt Minerva.

Realizing that Anderson is "Eha", Freddy barges into his office disguised as a doctor.

Anderson is routed by the animals’ own ghost versions, and the rats surrender after a shotgun blast.

Knowing that Anderson has a terrible temper, insects are sent to bug him, especially to ruin his sleep.

When finally they confront the sleep-deprived Anderson, he is forced to return the hotel to Mrs. Filmore.

With all the problems resolved, the campers decide to continue enjoying their stay outdoors.

There are 38 black and white, pen and ink drawings by Kurt Wiese, endpapers, and a full color cover, both depicting scenes from the book.
