"Don't kill me!"

Her words were also in English and she spoke without the slightest accent. Chester and Colonel Anderson looked at her dumfounded.

"Are you English?" demanded Chester, taking a step toward her.

The girl staggered back.

"Keep away, please," she said.

"Are you English?" repeated Chester.

The girl recovered herself with an effort and forced herself to answer the lad's question calmly.

"No," she said, "I am an American."

"An American!" exclaimed Chester. "You are an American?"

"Yes," cried the girl, "and you will harm me at your peril. The United States--"

"Uncle Sam is a long ways off," said Chester quietly. "But I guess he can take care of you. I, too am an American."

"You!" exclaimed the girl eagerly, taking a step forward. Then, after a quick glance at his clothes, she shrank back.

Chester smiled.

"Don't judge me by these garments," he said. "I a.s.sure you I am an American, and my friend here," he indicated Colonel Anderson, "is a British officer. My other friend," pointing to Ivan, "is a Russian. So you see, you are among friends."

"Are you telling me the truth?" asked the girl fearfully, eying Chester searchingly.

"It is a habit I have," replied Chester quietly. "Yes, I am an American and if you have a mind to question me about anything American you will find that I am telling you the truth."

"What is your name?" asked the girl.

"Chester Crawford."

"Chester Crawford!"

Again the girl looked at him searchingly.

At last she asked: "And do you know another young American named Hal Paine?"

"Hal!" exclaimed Chester, startled at hearing his friend's name from this girl whom he had, to his knowledge, never seen before. "Of course. He is my chum. But he has never told me he knew a girl answering your description."

"Oh, I don't know him," replied the girl. "But I have heard of you both from a friend--a girl friend; and if you can tell me her name, I will be sure that you are Chester Crawford."

"How can I tell you?" asked Chester. "I know several girls. Was it Mary--"

"This girl," was the reply, "you met in Belgium. If you are truly Chester Crawford you will know who I mean."

"Do you mean Miss Johnson--Edna Johnson?" inquired Chester.

A happy smile lighted up the girl's face.

"I do! I do!" she exclaimed. "It was Edna Johnson. She wrote me a letter, telling me how she met two young American boys in Belgium and giving me their names. I have heard from her often and each time she has mentioned your names. She wonders what has become of you."

"Well," said Chester with a smile. "I'm here and Hal is some place between here and Belgrade, I expect. Now will you tell me who you are?"

"I am Helen Ellison of St. Louis," replied the girl, extending her hand.

Chester took the hand and turned to the others.

"Allow me to present my friends to you," he said quietly. "Colonel Anderson, of His British Majesty's service."

Colonel Anderson bowed.

"And Ivan Vergoff,"--this in French. "Ivan, Mademoiselle Ellison."

The big Cossack also bowed and acknowledged the introduction.

The girl smiled at both of them, and Chester was glad to learn that she understood French.

"And now," he said, "if you will tell me exactly where we are, I shall be greatly obliged."

The girl looked at him in surprise.

"You don't know where you are?" she asked.

Chester shook his head.

"You are now," said Helen, "just across the Serbian border from Bulgaria.

This house is the home of a friend of mine, Miss Thatcher, a Red Cross nurse. I met her in Belgrade where she was wounded. When it became evident that the Austrians were about to occupy the city, we came to the home of her friend here, a Serbian woman. That was before there was any talk of Bulgaria joining Germany. But now that war has been declared--"

"War declared!" exclaimed Chester.

"Why, I think so. Maybe there has been no declaration of war, but anyhow the Serbians and Bulgarians have been fighting across the frontier.

That's why I was so afraid when you knocked at the door to-night."

"And it was you who shot at me?" asked Chester.

"Yes," replied the girl. "And, oh, I am so sorry. If--"

"Never mind," said Chester soothingly. "You didn't hit me."

"I know I didn't, but I--"

"There, there, now," said Chester. "And where is your friend now?"

"She went away this morning and she hasn't come back yet."
