“Jimminy!” he gasped, and leaped for the door.

He was half way through it when he saw the bow of a dory sliding into view past the rocks at the end of the cove. Jumping back like a flash, he jerked the door shut and latched it noiselessly. For an instant he hesitated, heart pounding in his throat. Then he moved swiftly to the window, pulled himself up, squeezed through and plunged into the fringe of undergrowth about a dozen feet away.

But as he gained the shelter he realized that the popping of the engine had ceased and he heard the sound of voices. He dared not pause here, but sped on over the rough ground. It was not the same way he had come, but he cared nothing for that. The closeness of his escape had shaken him considerably, and he was trembling. It was not until he had pushed through the woods for a hundred feet or more that he began to slow down and recover himself.

“What a nut I am!” he muttered, wiping his forehead with the back of one hand. “They’ll never come here.”

And then, being what he was, he grew angry at himself for that panicky flight. If he had stayed at the edge of the woods he might have had a good look at the stranger without any special risk. He might even have gained some hint as to what the party was doing here. He had just about decided to turn and retrace his steps, when he stumbled and almost fell, saving himself only by a quick snatch at an overhanging branch. Then, looking down to discover what had tripped him, he saw the tins!

At first glance, indeed, they did not look like tins, but more like square, rectangular boxes covered with canvas. It was only by pressing one with his fingers that he felt the distinctive give of thin metal. There were a dozen or more in all, piled neatly in a cavity among the rocks and covered over with leaves and dead branches.

Filled with curiosity, Steve punched and prodded the top one inquiringly and ran his fingers exploringly over its surface. He was on the point of lifting it to test the weight, when the sound of voices behind him brought him upright with a gasp.

CHAPTER VII
THE LIGHTNING FLASH

For the barest second Haddon stood listening. Then he bent down again and made a frantic, scrambling effort to cover the tins. But as the voices came steadily nearer and the scuffling of feet began to sound in the dead leaves, he abandoned the attempt and darting a few steps to one side flung himself down behind a thick, low-growing mass of laurel. In a space so brief that he felt they must have heard him, the bushes were thrust aside and the footsteps ceased.

“—a rabbit, I guess, or maybe a bird,” said a voice. “It don’t matter, anyway. Here’s the stuff, half uncovered, too. Hang that Peters! I told him to— Here, catch hold, will you? We haven’t much time.”
