Trenmore, panting on the little balcony of the Threat of Penn, congratulated himself that earlier in the day he had observed those doors and those strangely placed inner bolts. Already men were banging and shouting outside; but Trenmore only chuckled.

"They'll need dynamite for that little job," he murmured happily. "I'm thinking the Servants put those doors there for just the purpose they're now serving. Sword, you were made for the hand of a man, not the grip of this cold metal thing!"

He was examining the bronze fist that held the great sword upright. Though the heavy door shook and clanged to the besiegers' futile blows, he was cool as if alone in the Temple. He had not yet even glanced down into the Hall of Justice.

Across the knuckles of the Hand of Penn ran a tiny line, green-edged with verdigris. It was a flaw, a crack in the age-old bronze.

His inspection completed, Trenmore sprang into action with the sudden wholeheartedness which was a disconcerting factor in his make-up. Throwing off his coat he removed a large handkerchief from the pocket, wadded it in his right hand and grasped the blade high up. Seizing the pommel in his left hand, slowly but with gathering force, he twisted at the sword. It did not move. His white shirt stood out in bulging lumps over his laboring shoulders. His face went dark red. The purple veins rose and throbbed on a forehead beaded with great drops of perspiration. He did not jerk or heave at the thing. He merely twisted and the leverage was terrific.

There came a loud crack, like the report of a pistol. Within the wall something dropped clanging, and the sword gave way so suddenly that Trenmore was hurled to the floor. Picking himself up, he calmly resumed his coat and stooped for the famous weapon. Not only had the bronze hand fallen in two pieces, freeing the grip, but the whole wrist had broken loose from the wall, leaving only a blank black hole.

Trenmore was not concerned for the mechanism so ruthlessly shattered. He cared only for the shining prisoner he had released. He raised it with both hands to the roughened grip. As he did so the yellow light from the dome slid flamelike down the long blade. It was a weight for any two ordinary men to carry; but the Irishman swung it up and over his shoulder with hardly an effort.

"You're a heavy one, my beauty, and no mistake," he muttered. "Even Terence Trenmore would not care to swing you many times together. But that which you struck would never strike back, I'm thinking."

And then at last, with the sword on his shoulder, he turned and looked down from the railing. The blows on the door had ceased. He now perceived the reason. Midway across the hall, with upturned faces and raised rifles, waited every man of the prison guard he had so successfully eluded. Trenmore's appearance was greeted with shouts and a scattering volley. Unhurt but considerably startled, he skipped back.

"Powers o' darkness!" he gasped. "I'm a fool or I'd have expected it. And now what am I to do, will you tell me that, Sword of Battle?"
