A moment more, and the white beam of the flashlight was playing on the face of the safe, and the silence of the room was broken by the faint, musical, metallic whirring of the dial. Bent forward, a crouching form in the darkness, the Hawk worked swiftly, a sure, deft accuracy in every movement of his fingers. With a low thud, as he turned the handle, the heavy bolt shot back in its grooves, and the ponderous door swung open. And now the flashlight's ray flooded the interior of the safe, and the Hawk laughed low—before him, lying on the bottom of the safe, neatly banded as they had come from the bank, were a dozen or fifteen little packages of banknotes.

The Hawk dropped on his knees, and reached for the pay bag. Ten thousand dollars was not so bulky, after all—if the denominations of the notes were large enough. He riffled one package through his fingers—twenties! Gold, yellow-back twenties!

There was a sort of beatific smile on the Hawk's lips. He dropped the package into the bag.

Tens, and twenties, and fives—the light, in a curiously caressing way, was lingering on the little fortune as it lay there on the bottom of the safe. There was only a pile or two of ones, and the rest was—what was that!

The smile vanished from the Hawk's lips, and, in a rigid, tense, strained attitude, he hung there, motionless. What was that—that dull, rasping, sound! It was like some one clawing at the wall outside. The window!

With a single motion, as though stirred to life by some galvanic shock, the Hawk's hand shot out and swept the packages of banknotes into the bag. He snapped off his flashlight. The room was in darkness.

That sound again! And now a creak! The window was being opened. Something black was bulking there on the sill outside—and something queerly white, a man's face, was pressed against the pane, peering in.

The Hawk glanced sharply around him. Inch by inch he was pushing the safe door shut. He could not reach the door leading to the clerks' office, for he would have to pass by the window, and—he shrank back quickly, the safe door closed but still unlocked, and crouched low in the corner against the wall. The window slid up to the top, and with a soft pad, like some animal alighting on the floor, the man had sprung into the room.

The Hawk's fingers crept into his pocket and out again, tight-closed now upon an automatic pistol. The other's flashlight winked, went out, then shot across the room, locating the desk—and once more all was darkness.

There was not a sound now, save the short, hurried breathing of the other, panting from the exertion of his climb. Then the man's step squeaked faintly crossing the room—and the Hawk, a few inches at a time, began to edge along the wall away from the neighbourhood of the safe.
