When Ken Holt and his friend Sandy Allen drive to a bus stop in their home
town to meet a visitor from Mexico, they have no idea that Ricardo Montez, through no fault of his own, will involve them in a series
of dangerous events.
Almost instantly, strange things begin to happen. Before more than a few hours
have passed, Ken and Sandy realize that the young Mexican attracts danger as surely as sugar attracts flies. Mystery piles on
mystery. What is the strange heirloom that isn't really an heirloom? Why has Ricardo's family been guarding the silver amulet for
three generations?
What begins innocently as a short excursion to show their new friend the
wonders of New York City becomes an adventure that takes the three boys thousands of miles to a Mexican city, high in the
mountains. There a desperate battle of wits develops between the boys and two sinister strangers intent on possessing the amulet ––
the key to a long-forgotten treasure.
How Ken and Sandy pit all their ingenuity against the criminals' diabolical
cleverness, and how they uncover the amazing secret of the plumed serpent, makes another suspense-charged Ken Holt mystery.
