"What do you make of it, Mr. Moore?" the junior operator wanted to know.

"Of that?" said Peter. "Nothing—nothing at all. By the way, I forgot to tell you that the captain has issued strict orders forbidding subofficers to use the starboard decks. Always, when you're going forward, or aft, walk on the port side."

CHAPTER IV

Peter turned over the log-book and the wireless-house to Dale, a few minutes before midnight.

"Everything's cleared up. The static is worse, and KPH may want you to relay a message or two to Honolulu. If you have trouble, let me know."

"Yes, yes," replied Dale, looking over his shoulder nervously. "I will. Thanks."

Peter left him to the mercies of the static. As he descended the iron ladder to the promenade-deck, he imagined he saw some one moving underneath him. The figure, whoever or whatever it was, slid around the white wall and vanished as his foot felt the deck. He hastened to follow.

As he stepped into the light a low, sibilant whisper reached him. At the cross-corridor doorway he was in time to see the flicker of a vanishing gray garment and a sandaled foot on a naked ankle flash over the vestibule wave-check. He shook open the door and followed.

A vertical stripe of yellow light cleaved the dark of the corridor as a door was quietly shut. He heard the faint, distant click of a door-latch. Counting the entrances to that one, and sure that he had made no mistake, he rapped. The near-by clank of the engine-room well was the reply. He tried the handle. It was immovable. He struck a match. It was stateroom forty-four.
