The Phantom smiled faintly. “I know you acted for what you thought your daughter’s best interests. It is not for me to criticise your conduct in the matter. I can readily see—— But wait.” The Phantom’s brow suddenly clouded. “How many letters did you intercept?”

“I think there were two. One came in the spring; the other late in the summer. Yes, I am quite sure there were only two.”

The Phantom’s narrowing gaze swept the older man’s face. His lips tightened into a grim line. “The letter I mailed in the spring was the one in which I told your daughter of my removal from Azurecrest to Sea Glimpse,” he explained in tense tones. “I had promised to keep her informed of my movements so that she could communicate with me if she should ever need me.” He paused for a moment. “Have you any idea where your daughter might have gone? Didn’t she say anything that suggested what her plans were?”

“She talked rather incoherently at breakfast, but said nothing about intending to go away. When I received her message later in the day, it occurred to me that she might have gone in search of you. You had been mentioned several times in our talks together, and I thought that——”

“If her intention was to find me, she probably went to the wrong place,” gravely interrupted The Phantom. “Not knowing of my removal to Sea Glimpse, she naturally would look for me at Azurecrest. I sold the place through a broker and never even learned the name of the present owner. But her going to Azurecrest doesn’t explain her absence for the past twenty-four hours. She would naturally return at once upon learning that I was not there. The trip by train takes only two or three hours. I fear something must have happened to her on the way. Well, we shall soon learn——”

He dashed across the room, snatched up the telephone from its stand in a corner, and, after being connected with the long-distance operator, gave his old number at Azurecrest. A wait followed. The Phantom stood tense and rigid, while Mr. Hardwick dazedly drew his palm across his forehead. He gazed expectantly at The Phantom while the latter spoke briefly into the transmitter. Finally, with a puzzled look in his face, The Phantom hung up.

“The present owner of Azurecrest is a Mr. Slade,” he announced. “I just had him on the wire. He tells me nothing has been seen of Miss Hardwick, or of any person resembling her.”

Mr. Hardwick looked as if he did not quite know whether to feel relieved or discouraged. The Phantom grasped his hand.

“Don’t worry,” he said in a tone of hopefulness which he was far from feeling. “We will find your daughter. I shall communicate with you as soon as I learn something.”

He squeezed the older man’s hand and walked out. Though he could not understand why, his interview with Hardwick and his brief talk with Slade had intensified his fears and misgivings. It seemed as though the mystery of Helen’s disappearance had become darker and deeper. Suddenly, as he stood irresolute on the doorstep, he heard someone call his name. A limousine had silently drawn up at the curb, its sides of burnt sienna flashing brilliantly in the sunlight, and at the window, beckoning him with a smile and a nod, he saw a woman’s face. He stepped forward, and the woman leaned slightly from the window.
