"My moment will come," he reflected, "when the woman falls asleep. Then I can let myself out."

But the occupant for whom 1313 had been reserved was in no hurry for sleep. Morosini heard her moving about, and ventured to peep. He saw a small woman, young and rather pretty, of what might be classified as the "governess type." She did not undress, but seemed restless. Fussing round the room, she shot up the green blind and opened the window. Then she flew to the door. There had been a faint knock. Maurice peered from his hiding-place, and saw another woman come in. She, too, was plainly dressed, but older and with a harder, more experienced face.

"What can Nella be doing?" the trapped prisoner wondered. If she were still at the telephone bureau she must know that 1313 now had an occupant. Poor girl! Her misery must be equal to his.

Nella did know. She had seen the young woman go in. When no alarm followed, however, the girl's stopped heart beat again. But the situation had become impossible. She seized the first chance to call Teano. "It's too late for you to help, even if you could get in again," she whispered into the telephone, fearing to be overheard by some one passing. "A lady has gone into 1313 for the night. And I'm supposed to shut my window and go off duty in half an hour. Here comes Shannon, the night watchman, now."

As she spoke, a woman knocked at the door of 1313. Nella listened; soon she could hear voices speaking earnestly. Then they grew loud and shrill. "The women are quarrelling!" she thought. "Can it have anything to do with Maurice?" The transom snapped shut as she asked herself the question. The speakers were afraid of being overheard. That, at least, proved they believed themselves alone together!

"Well, here I am. I've given you time enough to make up your mind, haven't I, Miss Gibson?" began the new-comer.

"Yes, and I have made it up," answered the younger. "I don't say you're not acting in good faith. The note you brought to the dock looks like Mr. Odell's handwriting. And it's just as you said it would be. I found no letter of instructions waiting here. All the same, Miss Parsons, I won't give up the jewel till morning, when I've made sure the person I expected is not going to call."

"You are silly!" cried the other. "Now, how could I have known there was a jewel coming with a Miss Gibson on this ship, if I wasn't all right?"

"That's true," the younger woman admitted. "I don't see how you could have known except from Mr. Odell. But I'm not taking chances! If nobody else shows up before nine to-morrow morning, why then——"

"I have to go west to-morrow morning," explained Miss Parsons, her voice quivering with impatience. "I can't wait. I told you so on the dock. You must give me the thing now."
