The fourth was Betty, of whom, unlike three of her sisters, we seem to know too much. The curse of the Pitt blood was strong in her. Lord Camelford, her nephew, speaks of her 'diabolical disposition,' and says concisely that 'she had the face of an angel and the heart of all the furies,' and that she 'formed the most complicated character of vice that I have ever met with.' Family testimony is not always the most charitable, but outside witnesses in no way mitigate these expressions. Lord Shelburne says that she was received nowhere, owing to her profligate life. Horace Walpole brings an infamous charge against her, which we may well hope is a distortion of the natural fact that for some time she took up her abode with her eldest brother Thomas; though Thomas on parting with her said that her staying with him was extremely distasteful to him. She, in any case, openly lived as his mistress with Lord Talbot, a peer as eccentric as herself, and who promised her marriage, she said, whenever he should be free from the incumbrance of Lady Talbot.[34] Afterwards she went to Italy, became a Roman Catholic, started from Florence with the declared intention of marrying Mr. Preston, a Leghorn merchant, who seems however to have been unequal to the occasion.[35] Then she returned to England, virulent against her brother William, 'whose kindness to her,' says Horace Walpole, no biassed witness, 'has been excessive. She applies to all his enemies, and, as Mr. Fox told me, has even gone so far as to send a bundle of his letters to the author of _The Test_[36] to prove that Mr. Pitt has cheated her, as she calls it, out of a hundred a year, and which only prove that he once allowed her two, and, after all her wickedness, still allows her one.'[37] And yet on occasion she could call William the best of brothers and of men.[38] This, too, was characteristic of the breed. At this period of her life she called herself, heaven knows why, Clara Villiers Pitt, or Villiers Clara Pitt (there is an engraving of her with the latter designation), and published a pamphlet recommending magazines of corn. Of her perhaps too much has been said; but it is necessary to demonstrate that William's family relations were not always easy: Thomas reviled him, Elizabeth reviled him, Ann, whoever was in fault, caused him much trouble, while Thomas's son, whom he peculiarly cherished, regarded him with peculiar animosity.
