Barney reined in nearer the low wall. From his saddle he could see the grounds beyond through the branches of a tree. As he looked his attention was suddenly riveted upon a sight that sent his heart into his throat.

Three men were dragging a struggling, half-naked figure down the gravel walk from the sanatorium toward the gate.

One kept a hand clapped across the mouth of the prisoner, who struck and fought his assailants with all the frenzy of despair.

Barney leaped from his saddle and ran headlong after Butzow. The lieutenant had reached the gate but an instant ahead of him when the trooper, turning suddenly at some slight sound of the officer's foot upon the ground, detected the man creeping upon him. In an instant the fellow had whipped out a revolver, and raising it fired point-blank at Butzow's chest; but in the same instant a figure shot out of the shadows beside him, and with the report of the revolver a heavy fist caught the trooper on the side of the chin, crumpling him to the ground as if he were dead.

The blow had been in time to deflect the muzzle of the firearm, and the bullet whistled harmlessly past the lieu-tenant.

"Your majesty!" exclaimed Butzow excitedly. "Go back.

He might have killed you."

Barney leaped to the other's side and grasping him by the shoulders wheeled him about so that he faced the gate.

"There, Butzow," he cried, "there is your king, and from the looks of it he never needed a loyal subject more than he does this moment. Come!" Without waiting to see if the other followed him, Barney Custer leaped through the gate full in the faces of the astonished trio that was dragging Leopold of Lutha from his sanctuary.

At sight of the American the king gave a muffled cry of relief, and then Barney was upon those who held him. Astinging uppercut lifted Coblich clear of the ground to drop him, dazed and bewildered, at the foot of the monarch he had outraged. Maenck drew a revolver only to have it struck from his hand by the sword of Butzow, who had followed closely upon the American's heels.

Barney, seizing the king by the arm, started on a run for the gateway. In his wake came Butzow with a drawn sword beating back Stein, who was armed with a cavalry saber, and Maenck who had now drawn his own sword.

The American saw that the two were pressing Butzow much too closely for safety and that Coblich had now re-covered from the effects of the blow and was in pursuit, drawing his saber as he ran. Barney thrust the king behind him and turned to face the enemy, at Butzow's side.

The three men rushed upon the two who stood between them and their prey. The moonlight was now full in the faces of Butzow and the American. For the first time Maenck and the others saw who it was that had interrupted them.
