“Thank you. And keep the matter quiet, you know,” West added. “We want an exclusive story for the ‘Star’ if anything comes of it.”

“I understand. And, say,” said Jack as he turned away, “I’ll take my camera, too. I may be able to get a snap of them, if I see anyone.”

“Good idea. A picture would help to land them, if they are the fellows we want; and we could run it in the paper with our story. Go ahead, Jack, and good luck.”

Jack was not long in wheeling home and securing his folding Brownie; and a half hour later found him pedalling slowly along the quarry road near the point several miles from the city where the suspicious foreigners had been seen to enter the woods.

An hour passed, however, and he had seen no doubtful characters, and finally dismounting at the entrance to a path he knew to lead toward the old stone quarry, Jack concealed his wheel in a thicket, and set off to make an investigation in that direction.

A moment after he came to a halt with a sharp exclamation. In the path at his feet lay a murderous-looking stiletto. Picking it up, he examined it. Yes; it was of foreign make. And the still damp mud stains on the side of the blade which had lain uppermost showed it had been but recently dropped.

Apprehensively Jack cast a glance about him, almost immediately to utter a second suppressed exclamation. Emerging from the woods on the opposite side of the road was a short, dark man—undoubtedly an Italian.

With beating heart Jack watched him. Was he one of the men he was looking for?

In the middle of the road the stranger halted, looked sharply to right and left, and came quickly forward. Darting from the path Jack threw himself on the ground behind a bush, and the next moment the man hurriedly passed him. He was soon out of sight, and rising, Jack placed the dagger carefully in an inside pocket, and determinedly set off after.

Half a mile he followed the Italian amid the trees. Then there appeared the light of an opening, and going forward more carefully, Jack found himself on the edge of the quarry clearing. The foreigner was hurrying along the brink of the excavation, evidently heading for a small tumble-down cabin at its farther end.
