The skylight referred to was situated directly over the cabin table, so that, its sash being then raised some six inches to admit the night air, it afforded a ready means of eavesdropping. Springing lightly up the cabin steps in his stocking feet, Jack took a cautious survey of the deck. The awning had been taken in at nightfall, and a full moon shone overhead, making the whole deck as light as day. Close beside the skylight, lashed against the cabin, stood a water-butt; and bending carelessly over this he saw one of the native crew. Calling out sharply, he bade him go forward, and the fellow, muttering some half-audible excuse about wanting a drink, slunk away.

“A lascar after water; I don't think he was spying,” said Jack, diving below again. “All the same, we'll keep an eye aloft; that rascally Salambo may have an accomplice among the crew.”

“Very likely; but as I was saying,” resumed Don, in a lower key, “the thief has had ample time to make himself scarce. Now the thing is—how are we to nab him?”

“Why, there's just the difficulty,” said Don, with a despairing gesture. “They all sleep ashore except one or two; and by the time we woke the governor, explained matters to him, and got the fellows started, there'd be no end of delay. Besides, the rascal would naturally be on the look-out for the peons, and either give them the slip or bribe them to let him off.”

“Just what I was going to say,” continued Don. “The schooner, you see, sails for Colombo in two or three days' time at the most, and it would put the governor to no end of inconvenience to despatch half-a-dozen peons on an errand like this just now. Fact is, I doubt if he'd do it at all, and we might go whistle for our pearls. No, I've a better plan than that to propose. There's no need to trouble the guv at all; we'll go ashore and capture the thief ourselves.”

“Capital!” cried Jack; “I'd like nothing better. When shall we start?”

“At once. There's a bright moon, the fellow has only about an hour's start, and with ordinary luck we ought to run him down by daybreak at the very——”
