"Now we can keep on our guard." The play went on, and, for the time being, the boys and the girls paid no further attention to Link Merwell.

Just as the final curtain was being lowered, Dave looked up toward the balcony.
"He has gone," he announced.
"Perhaps he was afraid we'd come after him," suggested Phil.
"Maybe he came downstairs to watch for us," added Roger.

"Keep your eyes open when we go out." They did as the senator's son suggested.

They saw nothing of Merwell in the foyer, but came face to face with the former student of Oak Hall on the sidewalk.

He glared at them, but then seeing Dunston Porter at Dave's side, slunk behind some other people, and disappeared from view.
"My, what an ugly look!" said Laura, with a shiver.
"He looked as if he wanted to eat somebody up," was Jessie's comment.
"Oh, Dave, you must be careful!" "I wish his father's ranch wasn't so close to Mr.Endicott's," continued Dave's sister.
