"Do you know where she went?"

"Yes; to the home of a peasant about six miles from here. His wife is sick and Miss Thatcher has been attending them since she has been well enough to do so."

"And you were left here all along?" said Chester.

"Yes, but I wasn't afraid until this afternoon, when half a dozen Bulgarians crossed the frontier and tried to get in the house."

"The did?" exclaimed Chester angrily. "I wish we had been here."

"So do I," said Helen. "They knocked on the door, but I wouldn't let them in. Then they threatened to break the door down, but an officer came up at that moment and ordered them away. They went sulkily and one of them called back that they would return. That's why I was afraid when you knocked a little while ago."

"And no wonder," replied Chester. "It must have been a terrible day for you."

"It has indeed," said the girl weakly.

Chester sprang toward her quickly and took her gently by the arms, just as it seemed she would fall over in a faint. He seated her in a chair, and poured her a gla.s.s of water from a pitcher on a nearby table.

After drinking the water the girl appeared refreshed.

"So foolish of me to get weak like that," she said, smiling.

"It's no wonder," returned Chester. "It's just the reaction. You'll be all right in a minute or two."

The lad was a good prophet; and five minutes later Helen was talking and laughing vivaciously. All four were having a good time, when Chester's ears caught a faint sound from without.

The lad paused as he was about to say something in reply to one of Helen's questions and listened intently.

"What's the matter?" asked Helen.

"Oh, nothing," said Chester, and continued his remarks.

A few moments later, however, he arose, and asking to be excused for a moment, stepped toward the door which Ivan had broken to permit their entrance; just beyond he caught sight of a dark shadow.

"As I thought," he muttered. "They have come back."

He returned to the door of the parlor and summoned the big Cossack.

"Oh, Ivan," he called. "Come out here a minute."

The Cossack came up to him and Chester led him toward the door.

"What can you see out there?" he asked.

Ivan poked his head out and looked around.

"Ho!" he exclaimed suddenly and leaped out.

A moment later Chester heard the sound of a brief struggle and then Ivan reappeared dragging a man after him.

"I've got him," said the giant, laughing loudly.

The laughter attracted the attention of Helen and Colonel Anderson, who came from the parlor to learn the cause of it.

Helen gave a cry of fear as her eyes fell upon Ivan's prisoner.

"Who is he?" she exclaimed.

"Oh, just some fellow who was spooking around outside," replied Chester.

But Helen was not to be fooled thus easily.

"It is one of the Bulgarians who were here this afternoon," she cried, and addressed the man in his own tongue. Then she turned to the others.

"He says the others are coming," she cried. "He came on ahead of them."

"Oh, is that so?" said Chester quietly. "Well, they'll have a different reception this time."

He told the others what the girl had learned.

Colonel Anderson received the news quietly.

"We'll be ready for them," he said.

But Ivan was not so calm when he heard what Helen had told Chester.

"So there is going to be a fight at last, eh?" he cried in a loud voice.

"What are a dozen or so of these Bulgarians? I know them of old. Cowards and traitors all. I have had an experience with more than one of them. We are good for a dozen or two of them, if we can keep them in front of us.

Oh, yes, the Bulgarians are great fighters--from behind."

"Is there any way we can fix up that door?" asked Chester.

Colonel Anderson shook his head.

"I am afraid not. Ivan has shattered it beyond repair."

"Then it shall be my post to guard," cried Ivan. "No Bulgarian shall come through there."

"There are not many other places they can come through," said Helen.

"Only two windows and a second door, in the rear of the house. I shall guard one of the windows myself."

"You are not afraid?" asked Chester.

"Not now, that I have friends with me."

"All right. Colonel Anderson, I'll take this other window here, near Miss Ellison. You shall guard the back door."

"The first thing to do is tie this fellow up," said Anderson, indicating the Bulgarian.

Ivan stepped forward, and taking a piece of rope that Helen gave him, tied the man up tightly.
