"I've asked the doctor," Garth answered. "He says that the studied manner in which she threw us off the track when we caught her crying over McDonald, and her failure to lose complete control of herself when she was arrested indicate that her trouble is curable. It seems to have been brought on by her intolerable life in this gloomy house with an invalid whom she didn't love, while her affection for Reed increased hopelessly. Her illness was broken by such periods of apparent sanity as she had last night and to-day. I rather think Reed and she may be happy yet."

Nora smiled wistfully.

"Then," she said slowly, "I almost wish we had kept Taylor's secret better than he did himself."


CHAPTER XIX

PAYMENT IS DEMANDED FOR THE GRAY MASK

The approach of the moment when she must testify against Slim and George; must tell in public the details of that tragedy which had played such havoc with her, drove Nora into a morbid humor which neither Garth nor the inspector could alter. She followed Garth on the stand. She was dressed in black. The appeal of her personality was irresistible. It was clear that if the two criminals had ever had a chance Nora would destroy it.

Slim and George sat by their counsel. George could not quite hide the animal character of his face, but he had managed to soften it somewhat. Evidently he endeavoured to impress the jurors with the idea that he was a good-natured fellow who had been involved in the case through some curious mischance. At Nora's appearance, Garth noticed, there came into his eyes a survival of the passion he had so recklessly declared in the steel-lined room.

Slim, on the other hand, let slip nothing of the criminal. His quiet clothing gave him an air almost clerical. His sharp features expressed a polite interest. He could not, a casual spectator would have said, be capable of the evil with which he was charged.

Garth watched the men perpetually. He saw the hatred slip through while he quietly told the story that would condemn them to death. During Nora's recital, too, both men exposed something of their powerful desire for revenge against these two who quietly droned away their lives.
