"Better tell the Professor what you think," suggested Tad.
"Oh, I shouldn't dare to do that," protested Walter.
"We usually say what we think in this outfit. Oh, Professor!"
"What is it, Tad?"
"Did you know we had a visitor in this camp tonight?"
"From the evidences at hand I should say we had had several of them."
"I don't mean it in that way. I am not saying that the disturbance here tonight was caused by any outside agency. Chunky is sure he saw a ghost. Maybe he did. Chops knows he saw a spook and I, too, saw something that disturbed me a little."
"What do you mean?" demanded the Professor, fixing a keen gaze on the face of Tad Butler.
"There was a strange man in this camp tonight."
"Was—was he the ghost-man?" stammered Chunky.
