The Case of the Green Medallion — Bernard Palmer

Felicia Cartright, a petite blonde who is one of the most popular students at the Wellington School for Girls, has a surprising inclination toward mysteries. If a mysterious situation arises it either makes its way to Felicia, or Felicia somehow finds it. Though this is a bit trying for her happy-go-lucky room-mate, Joan Bailey, it does prevent life from becoming monotonous. Felicia and Joan travel to the home of a classmate only to discover that their classmate's father is the subject of threats and accusations. Felicia and Joan search for clues that will prove the man's innocence. Or is he really innocent? As they search for clues, the mystery becomes darker and more sinister. Will they ever get to the bottom of what really happened?

They had breakfast and went out into the chill morning air to follow the tracks of the person who had stood beneath the cabin window the night before.
"He was in a hurry," Sylvia said, pointing to the long, sliding imprints of the snowshoes. "A big hurry. We must have frightened him."
"Then that makes us even," Joan put in. "He certainly frightened us."
They fastened on their skis and followed the trail in the soft snow. The fellow had indeed been in a hurry. He had gone stumbling and sliding over drifts, through trees, and around clumps of brush, until he reached the main road.
There he had taken off his snowshoes and gotten into a car.
"What do you know!" Joan exclaimed.
The girls examined the tracks and looked at one another in amazement.
"Now why would anyone drive over here in a car and sneak up to look in your cabin, Sylvia?" Felicia asked.
The other girl shook her head. "It would have to be something important for him to go to all that trouble."
"And secretive," the Cartright girl added. "He walked more than a mile on snowshoes through the forest when he could have driven directly to the cabin."
"The fact that he ran means that he didn't want to be seen," Joan added.
Felicia's face lighted. "We have our first clue!"
