“Because you nearly fainted the other day when you heard it mentioned,” returned Cora, “and we saw that same man over at the camp to-day. His name is Higby.”
The girl started violently, but whether she would have admitted it they did not know, for just at that moment a call came from the depths of the woods:
“Nina, Nina!”
“My people are looking for me!” exclaimed Nina. “It wouldn’t do for them to find me here talking with you. They’re suspicious of everybody. I’ll have to go.”
“But we must see you again,” said Cora. “We simply must. Can’t you come over to our place and have a long talk with us? We live at Camp Kill Kare, only about four miles from here.” And she hastily gave the needed directions for finding the way.
Again the cry arose from the woods, but nearer this time.
“Nina, Nina!”
“Perhaps I will come,” said Nina hurriedly. “But you had better not come over to the camp again. If they suspect anything they will shut me up in one of the vans until they go away. Good-bye,” and she scurried away into the woods.
The girls looked after her regretfully and then climbed into their car and drove ahead to where the boys were waiting for them with more or less patience.
“Well, how did you amateur sleuths make out?” asked Jack, as they drew alongside.
