The stretcher-bearers slid the second convalescent out of the ambulance.

"Now!" whispered Charlie. "Do as you are told."

Half understanding, yet still much puzzled, the girl went around to the rear of the ambulance. It was half dark within, but she saw the man lying on the third stretcher, the one overhead, put out a hand and beckon her. She could see nothing of his face, his head was so much bandaged. One arm seemed strapped to his side, too.

The engine of the car began to purr. Charlie clashed the clutch. Ruth jumped upon the step, and then crept into the covered vehicle. The car leaped ahead.

She heard Jennie Stone exclaim in utter amazement:

"Well, what do you think of that? What did I tell you, Helen? She is actually running away."

In half a minute the ambulance was out of the courtyard and the dust of the village street wan rising behind it, as Charlie Bragg swung the car into high gear.

This was adventure, indeed!
