"He's driven inside the building," she decided. "Unless I get in there somehow, I'll never discover what is going on."
Penny debated, but in the end curiosity conquered fear. She left the roadster and stealthily made her way toward the sawmill.
CHAPTER XVIII
At the Old Sawmill
From the outside, Penny could not have told that the old mill was in use. It was surrounded by unkempt trees and shrubs which hid it from the road. Cracks in the decaying boards had been carefully patched so that no light from inside could show through.
Keeping behind the bushes, Penny made a complete tour of the building. She could find no means of entrance other than the main double doors through which the truck had driven. Only after a second minute inspection did she notice a small window at the rear well above the level of her head.
"If I can get up there I might be able to see what is going on inside," she thought.
Even on tiptoe she could not reach the window. Going down to the river she found an old orange crate which had washed up on the bank. Carrying it back to the window she set it underneath and climbed up.
She peered into the building. The window opened directly into a dark, deserted little room, but directly beyond she could observe several men moving about. It was impossible to see what they were doing.
