“By the jumping!” ejaculated Whitie Burns, heavy with admiration. “You got a head on you, Cap!”

“It's a good thing for some of you that I have,” returned Malone complacently. “But don't stand jawing all night. Go on, now—get busy!”

There was no surprise in Jimmie Dale's face—he had chosen his position behind a pile of cases that he had been extremely careful, as a man is careful when his life hangs in the balance, to assure himself were empty. None of the four came near or touched the pile behind which he stood; but, here and there about the room, they pulled this one and that one out from various stacks. In scarcely more than a moment, the room was completely transformed. It was no longer a storeroom for surplus stock, for the storage of bulky and empty packing cases! From the cases the men had picked out, like a touch of magic, appeared a veritable printing plant, an elaborate engraver's outfit—a highly efficient foot-power press, rapidly being assembled by Whitie Burns; an electric dryer, inks, a pile of white, silk-threaded bank-note paper, a cutter, and a score of other appurtenances.

“Yes,” said Jimmie Dale very gently to himself. “Yes, quite so—but the plate? Ah!” Malone was taking it out from the middle of a bundle of old newspapers, loosely tied together, that he had lifted from one of the cases.

Jimmie Dale's eyes fastened on it—and from that instant never left it. A minute passed, two, three of them—the four men were silently busy about the room—Malone was carefully cleaning the plate.

“They will raid to-night. Look out for Kline, he is the sharpest man in the United State secret service”—the warning in her letter was running through Jimmie Dale's mind. Kline—the real Kline—was going to raid the place to-night. When? At what time? It must be nearly eleven o'clock already, and—

It came sudden, quick as the crack of doom—a terrific crash against the bolted door—but the door, undoubtedly to the surprise of those without, held fast, thanks to the bolt. The four men, white-faced, seemed for an instant turned to statues. Came another crash against the door—and a sharp, imperative order to those within to open it and surrender.

“We're pinched! Beat it!” whispered Whitie Burns wildly—and dashed for the trapdoor.

Like a rat for its hole, Marty Dean followed. Malone, farther away, dropped the plate on the floor, and rushed, with Moulton beside him, after the others—but he never reached the trapdoor.

Over the crashing blows, raining now in quick succession on the door of the room, over a startled commotion as lodgers, roomers, and tenants on the floor above awoke into frightened activity with shouts and cries, came the louder crash of a pile of packing boxes hurled to the floor. And over them, vaulting those scattered in his way, Jimmie Dale sprang at Malone. The man reeled back, with a cry. Moulton dashed through the trapdoor and disappeared. The short, ugly barrel of Jimmie Dale's automatic was between Malone's eyes.
