Came another sharp knock on the door. Mabel advanced and threw it open.
Three men stood in the doorway, and all removed their hats at sight of her.
“What is it?” demanded Mabel.
“We are searching for a man named Von Blusen, who is aboard this ship. We trailed him down the deck here, and he disappeared. Have you seen him?”
“I know no one by that name,” returned Mabel.
“He’s a young fellow,” went on the spokesman of the three, “and a very smooth-spoken chap. All the other cabins are locked but this one. I happen to know that this door was open a few minutes ago. I thought he might possibly have come in here?”
He looked at Mabel inquiringly.
“I know no one by that name,” declared the girl again.
“Perhaps you know him by some other name, then?”
Mabel did not reply.
