"Our instructions," Jack continued, "are to stay here pending further orders."
"Maybe we'll get them soon," said Frank.
"Yes; and maybe we won't."

"That's what worries me."
There was a knock at the door.
"Come in," Frank called.
A bell boy entered with a second cablegram.
Jack tore it open hastily.
"Hurray!" he cried.
