"Well, let's get out and learn the worst," cried Tom.

He was the first to leave the stateroom, and as he rushed along the passages which were now brilliant with light he saw other half-clad passengers bent on the same errand as himself, to get on deck and learn what had happened.

"Wait, Tom!" called Ned.

"Come along, I'm just ahead of you," yelled his chum from around a corner. "I'm going to see if Eradicate is up. He's an awful heavy sleeper."

"Bless my feather bed! That shock was enough to awaken anyone!" commented Mr. Damon, as he followed Ned, who was running to catch up to Tom.

Suddenly a thought came to our hero. The mysterious passengers in Stateroom No. 27! Surely this midnight alarm would bring them out, and he might have a chance to see who they were.

Tom thought quickly. He could take a turn, go through a short passage, and run past the room of the mysterious passengers getting on deck as quickly as if he went the usual way.

"I'll go look after Rad!" Tom shouted to Ned. "You go up on deck, and I'll join you."

Eradicate's stateroom was on his way, after he had passed No. 27. Tom at once put his plan into execution. As he ran on, the confusion on deck seemed to increase, but the lad noted that the vessel did not pitch and roll so much, and she seemed to be on an even keel, and in no immediate danger of going down.

As Tom neared Stateroom No. 27 he heard voices coming from it, voices that sent a thrill through him, for he was sure he had heard them before.
