Mystery of the Blazing Cliffs
The cliffs blazed with flame...an oval object rose into the sky...and the people of Rancho Valverde knew they had just seen a flying saucer! Charle Barron, the hot-tempered owner of the ranch, immediately armed his men for a search. Mrs Barron, a firm believer in UFOs, got ready to welcome the aliens. Only The Three Investigators stopped to question the bizarre events. Was Rancho Valverde really being invaded from outer space? Or could the wealthy Barrons be the victims of a brilliant hoax?
