"I've got the letter," she said; "and there's a note inside it from Mrs. Talboys." Robert Audley's pale face flushed a vivid crimson as he stretched out his hand to receive the papers. "The persons who stole Helen Maldon's love-letters from George's trunk in my chambers might have saved themselves the trouble," he thought. The letter from the old lieutenant was not long, but almost every other word was underscored. "My generous friend," the writer began—Mr. Maldon had tried the lady's generosity pretty severely during his residence in her house, rarely paying his rent until threatened with the intruding presence of the broker's man—"I am in the depths of despair. My daughter has left me! You may imagine my feelings! We had a few words last night upon the subject of money matters, which subject has always been a disagreeable one between us, and on rising this morning I found I was deserted! The enclosed from Helen was waiting for me on the parlor table. "Yours in distraction and despair, "HENRY MALDON. "NORTH COTTAGES, August 16th, 1854." The note from Mrs. Talboys was still more brief. It began abruptly thus: "I am weary of my life here, and wish, if I can, to find a new one. I go out into the world, dissevered from every link which binds me to the hateful past, to seek another home and another fortune. Forgive me if I have been fretful, capricious, changeable. You should forgive me, for you know why I have been so. You know the secret which is the key to my life. "HELEN TALBOYS." These lines were written in a hand that Robert Audley knew only too well. He sat for a long time pondering silently over the letter written by Helen Talboys. What was the meaning of those two last sentences—"You should forgive me, for you know why I have been so. You know the secret which is the key to my life?" He wearied his brain in endeavoring to find a clew to the signification of these two sentences. He could remember nothing, nor could he imagine anything that would throw a light upon their meaning. The date of Helen's departure, according to Mr. Maldon's letter, was the 16th of August, 1854. Miss Tonks had declared that Lucy Graham entered the school at Crescent Villas upon the 17th or 18th of August in the same year. Between the departure of Helen Talboys from the Yorkshire watering-place and the arrival of Lucy Graham at the Brompton school, not more than eight-and-forty hours could have elapsed. This made a very small link in the chain of circumstantial evidence, perhaps; but it was a link, nevertheless, and it fitted neatly into its place. "Did Mr. Maldon hear from his daughter after she had left Wildernsea?" Robert asked.
