"Go on and read," said the Earl.

Gwen read half to herself:—"'My dear daughter Maisie,'" and then said aloud:—"But that is Mrs. Prichard's name!"

"Read through to the end," said the Earl. And Gwen, with a painful feeling of bewilderment, obeyed orders, puzzling over phrases and sentences to find the thing she was to read for, and staggered a moment by the name "Cropredy," which she thought she must have misread. There was no clue in the letter itself, as she did not know who "Phoebe" and "Ruth" were.

Her father's observation of her face quickened as she visibly neared the end. She was quite taken aback by the signature, the moment it caught her eye. "Isaac Runciman!" she exclaimed. "Why—that's—that's....

"That's the name of Mrs. Marrable's father that old Mrs. Prichard lays claim to for hers," said the Earl quietly. "And this letter is written to his daughter, Mrs. Thornton Daverill, whose name is Maisie.... And old Mrs. Prichard's name is Maisie.... And this letter is in the keeping of old Mrs. Prichard." He left gaps, for his hearer to understand.

"Good God!" exclaimed Gwen. "Then old Mrs. Prichard is not mad." She could only see that much for the moment—no details. "Oh, be quiet a moment and let me think." She dropped the letter, and sat with her face in her hands, as though to shut thought in and work the puzzle out. Her father remained silent, watching her.

Presently he said, quietly still, as though to help her:—"Norbury told me last night what we did not know, that old Mrs. Marrable's name is Phoebe, and that Widow Thrale's is Ruth...."

"That old Mrs. Marrable is Phoebe and her daughter is Ruth." Gwen repeated his words, as though learning a lesson, still with her fingers crushing her eyes.

"And that Ruth is not really Phoebe's daughter but her niece. And, according to Norbury, she is the daughter of a twin sister, whose husband was transported for forgery, and who followed him to Van Diemen's Land, and died there." He raised his voice slightly to say this.

A more amazed face than Gwen's when she withdrew her fingers to fix her startled eyes upon her father, would have been almost as hard to find as a more beautiful one.
