"I promise you on my word of honour that the doctor need never know that you helped us."

But the woman only shook her head.

"What makes you hesitate?" continued Cyril. "Do you think I am trying to bribe you to do something dishonourable? Ah, that is it, is it?" He gave a short laugh. "Look at my wife, does she look like a criminal, I ask you?"

"She certainly doesn't," answered the nurse, glancing eagerly from one to the other and then longingly down at the money in Cyril's hand.

"Well, then, why not trust your instinct in the matter? My wife and I have been placed, through no fault of our own, in a very disagreeable position. You will know the whole story some day, but for the present my lips are sealed. International complications might arise if the truth leaked out prematurely." Cyril felt that the last was a neat touch, for the woman's face cleared and she repeated in an awe-struck voice: "International complications!"

"Germany! I can say no more," added Cyril in a stage whisper.

"Ah! The wretches!" cried the nurse. "One never knows what they will be at next. Of course I will help you. I ought to have known at once that it was sure to be all right. Any one can see that you are a gentleman—a soldier, I dare say?"

"Never mind who or what I am. It is better that you should be able truthfully to plead your complete ignorance. Now as to the uniform; have you one to spare?"

"Yes, indeed. I will go and get it immediately."

"All this mystery frightens me," exclaimed Priscilla as soon as they were alone.
