The night of her disappearance from the power house she called Von Lertz on the telephone.

"Can you come to my apartment, soon? At once if possible. It is very important. And please bring a sharp file with you—yes rather large—I'll explain—Thank you—Good-bye."

She hung up the receiver with a triumphant smile. The smile lingered as she deliberated on the events of the evening. She was very tired, but she must bring this latest affair to a successful close. The opportunity was too great to pass by.

She heard shortly the sound of Von Lertz's car drawn up to the curb and a few moments later the bell of the apartment rang. She ran to open it herself, and, as Von Lertz entered, she held up laughingly a little hand about whose wrist dangled one manacle of a pair of handcuffs.

"Now you know what I wanted the file for. Will you help me take it off?" She seated herself on a low stool beside the great armchair into which Von Lertz threw himself with easy familiarity.

"Take it off and I will tell you all about it. It's a long, long story, and I'm tired and when I get through I think you will agree with me that I have a right to be tired." With quick interest Von Lertz bent over the little wrist with its strange adornment, and as Dixie in low tones told her story, Von Lertz filed away at the manacle.

"The electrician mistook me for Madam Stephan, I think. I was standing by the power house and he came running past, followed by the chief watchman." She stopped meditatively. "Do you think I look like Madam Stephan?"

Von Lertz glanced up impatiently. "Hardly, to one who knows you, you are both dark. But the story. What happened then?"

"Oh, yes," Dixie, obediently and naively took up the tale convinced that she was really interesting him. "I was standing there and he called. I ran into the power house and threw the switch. Then there was this awful explosion and the whole plant went up in smoke and flame. The watchman ran in and arrested me. When someone called him out he handcuffed me to the gate. I saw a rubber glove in the electrician's box and I put it on. Then I pulled the handcuff over the switch and it melted and I got away, but I took one with me."

Dixie paused for breath and gazed at him soulfully out of great dark eyes, doubting for an instant her ability as a romancer.
