Secret of Goblin Glen — Phyllis A. Whitney

Trina has always thought it rather romantic to have a black sheep in the family. Forty years ago her Great-uncle Will Horst robbed a bank in a little town in New Hampshire. And now Trina is spending the summer there with friends of her parents, the first one in her family to go back to the scene of the crime. She soon finds reality less romantic than she had expected.

The long-ago robbery is anything but forgotten in Camberhills. People are still searching for the stolen money. It is rumored that the two robbers hid it in Goblin Glen, a gloomy, dark valley spiked with peculiar rock formations.

Many people are still full of smoldering enmity toward anyone related to the Horsts! Tex and Florida, the boy and girl in the family Trina is visiting, are far from friendly. There's no doubt about Galvin Sewell's animosity either. He is the grandson of the bank president who was ruined by the crime and he seems to hate Trina.

It's one thing to picture yourself being a heroine, finding a lost fortune and returning it to the rightful owner…but it's something else to find yourself suddenly in the midst of a real-life story full of angry and desperate people. Trina begins to feel desperate too. Into this seething situation come two long-haired young TV stars, the Buddy Brothers, who are to appear in the local Folk Festival. Both Trina and Florida are entranced-until they find that these boys, too, are searching for the lost treasure.
