"Say! I think I know something about that!" cried Walter Baxter, quickly. "Yes, I'm sure I do!"
"Did you see Martell take the suitcase?" demanded the youngest Rover, quickly.
"I can't say as to that, exactly. But I did see Martell sneaking off through the backyard, past the stable, with something under his arm—a big package wrapped up in a couple of newspapers."
"When was this?" questioned Jack, quickly.
"About four o'clock this afternoon."
"Just after we arrived at the Hall!" burst out Randy.
"What did he do with what package?" asked Jack.
"I don't know exactly, excepting that he went down past the stable on to the roadway that leads to the farm fields."
"Maybe he took the suitcase and threw it down in one of the fields," ventured Andy.
"You didn't see him come back?" asked Fred.
