"Yes," went on Betty, taking up the story, "didn't Mollie tell you that? She really fell from a tree as our auto passed, and at first we thought we had struck her." Betty shot a glance of inquiry at Mollie.

"No, I didn't tell that part," confessed the owner of the new car. "I was so flustrated, and I guess Grace didn't say anything either."

"No," answered the willowy one.

"Well, I'm here, at all events, but there is no patient," said the doctor, with a smile.

"Oh, we'll pay you for your call!" exclaimed Betty, quickly taking out her silver mesh bag. "How much——"

"No, no!" said Dr. Brown somewhat sharply, "you misunderstand me. I never accept a fee in a simple accident case. What I meant about there being no patient was that she has evidently gone away, possibly in a delirium, and in that case we had better search for her, for she may be badly hurt, or do herself some injury. You say she was in this room?"

"Yes," answered Mrs. Meckelburn.

"And you sat here in view of the door all the while?"

"Yes," spoke Betty. "She never came out of that door, I'm sure." Amy said the same thing.

"Then the only other possible solution is that she got out of the window," went on the physician, "for there is no other door from the room. We must look outside," and he crossed the apartment to the casement. It had been raised, and the shutters were open when the unconscious girl had been left alone.
