“Excitement,” Vera finished the sentence.

Three-quarters of an hour later Billy Webster had discovered the secret camp.

He and Vera were riding quietly when they came to the circle of hills which Peggy had described. Stopping their ponies they heard the sound of low voices before seeing any one.

“They Heard the Sound of Low Voices Before Seeing Any One.”

Dismounting, Billy asked Vera to wait until his return.

It seemed best that she should allow him to go on his adventure alone, and yet she watched his slender, boyish figure disappear, feeling wretchedly uneasy.

What absurd reason had Billy for wishing to take part in some trouble which assuredly was no affair of his? If anything happened to him, Vera knew that she would always blame herself.

But Billy was entirely unalarmed and, although he was supposed to be timid, he was not even nervous.

He walked straight ahead with his hands in his pockets and a friendly, curious expression in his big, clear eyes.
