“It is sort of weird, isn’t it?” agreed Judy. “We called her a phantom and then she—well, she just vanished. I can’t think how or where. Was she there when we heard that siren, Flo?”

“What siren?”

Apparently Flo had been so engrossed in the show that she hadn’t heard it.

“It was an ambulance we heard outside the theater right after the witch put her curse on Sleeping Beauty. An ambulance!” Judy exclaimed, a new possibility dawning upon her. “Do you suppose Clarissa—”

“Of course not,” Pauline interrupted. “She was in here watching the show, not outside on the street.”

“Who was in that ambulance?” Judy inquired

“We don’t know that,” Judy objected. “We don’t know how long her seat has been vacant. She could have slipped outside, for some reason, and been hurt in an accident. Come on, girls! We have to find out for sure.”

Grabbing their coats, they hurried outside to see what had happened. They were just too late. The ambulance with its wailing siren had already disappeared down the street. At the curb a taxicab with its rear fender smashed in was waiting to be towed away. The crowd that had gathered around the scene of the accident was beginning to thin. Judy spied a policeman and rushed over to him.

“We can’t find our friend. We think she may have left the theater and been hurt or something. Who was in that ambulance?” she inquired all in one breath.
