That forestalled conversation for the time being. When the young engineers, still relentlessly attended by Nicolas, sought their own rooms Hazelton was so drowsy that he undressed hurriedly and dropped into bed.
Later in the night Harry sat up suddenly in the dark. Some one was moving in the parlor that separated the two bedrooms. An instant after awakening Harry slipped off the bed, then stole toward the next room.
In the darkness he made out a moving figure. Like a panther Harry sprang, landing on the all but invisible figure.
"Now, I've got you!" Hazelton hissed, wrapping his arms around the prowler.
"And small credit to you," drawled Tom's dry voice. "Hist!"
"What's up?" demanded Hazelton, dropping his voice to a whisper.
"You and I are."
"But what's the matter?"
"I couldn't sleep," Tom whispered.
"You—troubled with nerves!" gasped Hazelton.
