"There's something noble about this face," said Mrs. Undercliff, ignoring the interruption, "and yet something simple. I think him more likely to be a cat's-paw than a felon." Having delivered this with a certain modest dignity, she laid the profile on the counter before Helen. The expert had a wonderful eye and hand; it was a good thing for society he had elected to be gamekeeper instead of poacher, detector of forgery instead of forger. No photograph was ever truer than this outline. Helen started, and bowed her head over the sketch to conceal the strong and various emotions that swelled at sight of the portrait of her martyr. In vain; if the eyes were hidden, the tender bosom heaved, the graceful body quivered, and the tears fell fast upon the counter. Mrs. Undercliff was womanly enough, though she looked like the late Lord Thurlow in petticoats; and she instantly aided the girl to hide her beating heart from the man, though that man was her son. She distracted his attention. "Give me all your notes, Ned," said she, "and let me see whether I can make something of them; but first perhaps Miss Rolleston will empty her bag on the counter. Go back to your work a moment, for I know you have enough to do." The expert was secretly glad to be released from a case in which there were no materials; and so Helen escaped unobserved except by one of her own sex. She saw directly what Mrs. Undercliff had done for her, and lifted her sweet eyes, thick with tears, to thank her. Mrs. Undercliff smiled maternally, and next these two ladies did a stroke of business in the twinkling of an eye, and without a word spoken, whereof anon. Helen being once more composed, Mrs. Undercliff took up the prayer-book, and asked her with some curiosity what could be in that. "Oh," said Helen, "only some writing of Mr. Penfold. Mr. Undercliff does not want to see that; he is already sure Robert Penfold never wrote that wicked thing." "Yes, but I should like to see some more of his handwriting, for all that," said the expert, looking suddenly up. "But it is only in pencil." "Never mind; you need not fear I shall alter my opinion." Helen colored high. "You are right; and I should disgrace my good cause by withholding anything from your inspection. There, sir." And she opened the prayer-book and laid Cooper's dying words before the expert; he glanced over them with an eye like a bird, and compared them with his notes. "Yes," said he, "that is Robert Penfold's writing; and I say again that hand never wrote the forged note." "Let me see that," said Mrs. Undercliff. "Oh, yes," said Helen, rather irresolutely; "but you look into the things as well as the writing, and I promised papa--" "Can't you trust me?" said Mrs. Undercliff, turning suddenly cold and a little suspicious.
