"Yes; you might as well bring them along," answered Professor Paul Brice. "That will save another trip downstairs. You can give your trunk checks to me, and I will see that the trunks are brought up from the station and placed in your rooms to be unpacked. After you've unpacked them, they will be marked with your names and placed in the trunk room."
It took the boys but a minute to reach the end of the hallway where their suitcases had been left. Those of the twins were still there, and also that belonging to Jack; but Fred's was missing.
"Hello! what's become of my suitcase?" questioned the youngest Rover, anxiously.
"Maybe somebody carried it upstairs for you," suggested Jack.
All looked around the hallway and in the nearby rooms, but the suitcase could not be found.
"Well, I don't think you need to worry," said Professor Brice lightly. "There is no danger of thieves around here. Probably some boy picked up the suitcase by mistake."
"Maybe," returned Fred; but then he looked at his cousins and shook his head slowly.
"I guess you suspect Nappy Martell and his cronies," whispered Randy on the way upstairs.
"I do!" answered Fred. "I think they took that suitcase to play a trick on me."
