The Secret of Grange Farm

by Frances Cowen

When Bette Danvers' holiday plans were upset, she immediately thought of Grange Farm and of the many summers she had spent there as a child. She would go back to the farm, she decided, and help her cousin with the harvesting.
But somehow Grange Farm didn't seem the same any more. All the old farm-hands had been sacked and a group of tough-looking men were installed in their place. Her cousin, Nicholas Ferndale, had changed too. He had grown a beard and was no longer the gentle, laughing Nicky she had known.
Inadvertently Bette stumbled upon the key to the mystery, and found herself in the midst of an adventure which involved her with dangerous, unscrupulous men.
Frances Cowen has written an exciting, fast-moving story which no girl will be able to put down until the secret of Grange Farm is at last unfolded.
