“Another cup of coffee, dad?” was her only reply.

Mr. Hardwick appeared not to have heard. “You know who I mean. The man they used to call The Gray Phantom. For several years he was regarded as one of the cleverest and most dangerous criminals the world has ever known.”

Slowly Helen raised her head. Her eyes, as they met her father’s, were steady and bright.

“That was because the world didn’t understand him,” she said with emphasis. “The Gray Phantom wasn’t really a criminal. He was only a—a sort of human dynamo whose energy happened to be turned in the wrong direction.”

“Isn’t that a distinction without a difference? A Robin Hood is an enemy of society despite the glamour with which he surrounds himself. However,” and Mr. Hardwick’s face softened quickly, “I am deeply in The Gray Phantom’s debt. He saved your life twice, and but for him I would now be a lonely and heartbroken old man.”

Helen nodded eagerly. “And the Assyrian collection, dad. You spent most of your life gathering it, and you were almost overcome with grief when it was stolen. The Gray Phantom risked his life and liberty in order to recover it and restore it to you. He wouldn’t have done that if he had been just an ordinary criminal.”

“True,” admitted Mr. Hardwick. “I shall be under obligations to The Gray Phantom as long as I live. The man has a number of excellent qualities, whatever may be said of his past. On the whole, it is not surprising that you have taken an interest in him.”

Helen’s eyes were lowered again.

There was a mingling of tenderness and worry in Mr. Hardwick’s face as he looked at her. “I know just how you feel,” he said softly. “A man who is trying to live down a dark past always exerts a strong romantic appeal on a woman of your impressionable age. I don’t know why it is, unless it pleases her to think he is doing it for her sake. It makes me think of your play, ‘The Master of His Soul.’ All last night, until the interruption came, I was wondering whether your Marius was not The Gray Phantom.”

Helen sat rigidly still for a moment. Then her lips began to twitch. She flashed her father a smile.
