"Think you can work it?" he casually asked, over his shoulder.

"I—I might, with less noise," the professor suggested.

"Hope my paper doesn't bother you. This is the only place I have to read since I gave up my room, you know."

Several times more, as Monsieur was holding his breath momentarily expecting the mystery of the combination to dissolve, the paper seemed to be stricken with an ague, till at last, hugging the safe to his chest, he indignantly stalked down the passageway and slammed the door of his room after him.

Tommy now arose and walked around his chair, and as I was leaving for my appointed place I saw him start on tiptoe in the direction of Doloria's stateroom.

Ten minutes later he appeared in the cockpit, helped her to the deck, and together they approached. Yet as they drew near the place I was standing she stopped, looking at me in pretty surprise, but came forward again with hands outstretched, saying:

"Oh, Jack, I thought you were terribly, dangerously ill!" And before I could reply Tommy was gurgling, with a fatuous grin:

"Why, hullo, Jack! I see you're up!"

"Are you better?" she asked, letting her hands rest in mine.

"D'you know," here Tommy interposed, not giving me a chance to answer, "that old whiz-bang devil told Doloria that if she spoke to you, or answered your notes, he'd have you jailed for interfering with a foreign country's accredited agent? Sure, he did! He stuffed her poor little head full of trumped-up international law that hadn't a grain of truth in it—to scare her, see? She was afraid to budge!"
