“Gee! half a minute, chief,” Patsy now cried, interrupting. “Yes, I’m right. Here’s the print of a bare foot.”

Patsy had discovered it in some loose earth near the garage and hastened to inspect it. There was no mistaking it, for it was distinctly outlined in the damp soil, and it showed plainly in which direction the man was going.

“He was heading for the house, chief, just as you have suspected,” Patsy added, turning to look for another.

“I was sure he would seek some dwelling,” Nick replied. “Which one was the only question. It naturally would be the one most safely and quickly approached, and that was why I came this way.
