Beginning with a writing desk in the cabin, we examined the book shelves and every nook and corner, then passed to the staterooms. These gave the same impression of having been swept clean—cupboards, presses, all were empty. Only in one drawer, delicately scented, was there a single item—a hairpin. Here, then, must be Sylvia's room, but otherwise it was devoid of any article. Equally unproductive did we find the galley, the crew's quarters, and a small cuddy forward.

Monsieur sat down and pursed his lips.

"They have anticipated our intention," he said, thoughtfully. "Doubtless the things were emptied into sheets, then either weighted and sunk, or taken in the boats. But she must have exerted her ingenuity. There absolutely must be some word left for us. Wait!"

Hurrying to the Whim he returned with his lens, while from the mate he had borrowed a caliper, a two-foot rule and a sail needle.

"Now we shall search scientifically," he cried. "Remember, that as no personal belonging remains, even the books being gone, we must infer they made a great effort to destroy everything that would leave a clue. They suspected the girl, too, and that made them doubly careful. What would she do then? Exactly as we would do—hide her message so the others could not discover it! Now, my boy Jack, you take the sail needle and probe cushions, pillows and mattresses! My boy Tommy, take my lens and look for places where the glue has been disturbed on furniture joints; I will measure the desk, piano, panels—everything—for a secret hiding place!"

"Well, I'll be darned," Tommy grinned. "You're some cop, professor!"

When each of us had finished and reported failure, Monsieur did not seem at all discouraged.

"Now we go to the second phase," he said. "Keep in mind, whenever you search for anything, that it may be under your nose. That is the place to look, not off at the clouds—and nothing is too insignificant to escape investigation. For see: I can write on a very thin piece of paper, roll it into a string, thread it into a bodkin, and weave it into a rug, curtain, quilt, and so forth; or press it lengthwise into a crack in the floor. A favorite way is to tie it to a real piece of string, and throw them carelessly into a wastebasket, thus making them appear to have been cut from a bundle. But there are a thousand ways! Now we proceed with this. Later we probe down gas jets, water spouts and outlets, empty lamp reservoirs, unscrew the backs of mirrors, search key holes, unravel carpets——"

"Heavens," I cried, seeing that in his zeal for doing this professionally he was making himself absurd; and Tommy burst into a hearty laugh, saying:

"Gezabo, there isn't a girl in a million who'd think of those places, and if she did she wouldn't credit us with enough sense to find 'em. Call off your bloodhounds! There's no message for us, that's a cinch! Let's get busy at once on something practical!"
