Chester had poured the boiling water upon the foe at the psychological moment indeed--for Ivan had been ready to dash forward at that exact minute and Chester had diverted the attention of the Bulgarians long enough for Ivan to reach them without being discovered.

Had the men not been otherwise engaged when he dashed from his place of concealment, they would doubtless have shot him down before he reached them. But the kettle of hot water had prevented them from bringing their revolvers to bear until too late.

Ivan descended upon them with a wild cry, and at sight of him the Bulgarians gave back. Eight of them there were, but they recoiled as a single man from the great Cossack.

A single shot Ivan fired from his two revolvers and then they were empty.

Quickly he reversed both weapons, and holding both by the barrels, he was among the enemy, striking right and left as fast as the eye could see.

Down went a man on the left with a cracked skull. A man on the right caught a glancing blow on the shoulder and also toppled over. Now the remaining six scattered and sought to get a position where they could shoot Ivan down without fear of injuring one of their own number. But Ivan prevented this by keeping close.

He at length seized one man by the neck--dropping the revolver he held in his left hand to do so--and held him before him as a shield.

Then he charged the others.

Ivan's eyes shone with a terrible fire as he darted forward. His hat was off and his long hair streamed in the wind. Holding his human shield as he did with his strong left hand, he raised his revolver aloft in his right, gripping it tightly by the barrel.

The nearest man of the enemy failed to skip aside quickly enough and the revolver crashed down on his head with a thud. That was the last of him.

A second, thinking to take advantage of this action, slipped upon the giant from behind and leveled his revolver at Ivan's head. But once more Ivan was too quick for him, and, whirling suddenly, hurled his revolver at the man.

The Cossack's aim was true, and struck squarely in the face with the sharp revolver, the man dropped to the ground. Now, besides the man he still held aloft, there were but three of the enemy left. With a loud cry, they turned and ran.

But Ivan had no mind to be balked of his prey. He still held a weapon, and he made good use of it. The weapon was the man he had been using for a shield. Raising him high above his head with his right arm, he hurled him forward, as a man putting the shot.

The human catapult sailed through the air and struck two of the enemy as it fell, carrying them to the ground, knocking the breath from the bodies of all three.

Ivan leaped forward quickly. Stooping, he picked up two men, one in each hand, and brought their heads together with an audible crash. Then he hurled one down upon the third man with great force, and stooping, picked up a revolver.

Quickly he dropped to one knee, and leveling the revolver, took careful aim at the remaining man, who was now some distance away and running swiftly.

"Crack!"

A report, a flash of flame in the darkness.

An imprecation from Ivan, a second report and flash of flame, and the man fell sprawling.

Ivan rose calmly. He surveyed the field of action with a critical eye.

Then, without a word, he turned on his heel and stalked back to the house. As he came to where Chester and Helen stood, he said quietly:

"Any more of them in here?"

"None," returned Chester. "You finished the lot."

"Good," said the Cossack. "I thought they had me once."

He uttered no further word, but made his way to the parlor, where he sat down as calmly as though nothing had happened.

"You go in there, too," said Chester to Helen. "I'll have a look at Anderson."

But the girl refused to obey this command and accompanied the lad to where the gallant Colonel lay, moaning feebly.

Chester dropped down and raised Colonel Anderson's head to his knee.

"How do you feel, old man?" he asked.

"Rather weak and dizzy," was the Colonel's mumbled response.

"Where did the bullet hit you?"

"Top of the head some place," and Colonel Anderson raised a feeble hand and pa.s.sed it over his head.

"Quiet now," said Chester. "I'll have you in the other room in a jiffy and we'll have a look at the wound. Will you make a light in the parlor, Miss Ellison?"

The girl hastened away to do as Chester requested and the lad a.s.sisted Colonel Anderson to his feet.

"Put your arm around my neck," the lad commanded. "Lean all your weight on me and I'll drag you into the other room. You're too big for me to carry."

Colonel Anderson followed instructions and Chester dragged him to the parlor, where he laid him on a couch. Then he bent over and examined the wound.

"Doesn't amount to much," he said finally, rising. "Will you get me some water and a cloth. Miss Ellison? Also, if by any chance you can find it, a piece of adhesive plaster."

"I can get them all," said the girl. "Miss Thatcher's kit is still here."

She hurried away and was back in a few minutes with the necessary things.

She lent Chester a hand and bathed the wound on the Colonel's head, while Chester unrolled the adhesive plaster. Then they bound up the wound.

Colonel Anderson then insisted on sitting up. He pa.s.sed a hand ruefully across his bandaged head and smiled faintly.

"Hurts a little, but not much," he said in answer to Chester's question.

"But now, if you'll tell me--"

He paused suddenly and raised a warning hand.

"What's the matter now?" demanded Chester anxiously.

"Thought I heard voices without."

With a bound Ivan left his chair and darted toward the door. He disappeared in the darkness.

"Ivan's fighting blood is up," said Chester. "I guess I'd better go after him. You guard the wounded man here, Miss Ellison."

He hurried after Ivan.

Outside the door he came upon a strange sight--a sight that caused him to cry out in merriment and thankfulness.

In his first gaze he saw four figures and the first he recognized as that of Hal, the next that of Nikol. These two stood quietly gazing at two other figures who were struggling nearby. Chester glanced at the other figures. They were Ivan and Anthony Stubbs and they appeared to be locked in a death grapple.

"Help! Help!" came Stubbs' voice.
