Pepys' diary provides a detailed primary source of Sandwich's career in the 1660s. They had a serious quarrel in 1663, when Pepys reprimanded Sandwich for living openly with his mistress, Elizabeth Becke, at her "mean house" in Chelsea. Pepys was concerned at the damage to their family's reputation, Sandwich's neglect of his official duties (thus risking the loss of any remaining influence he had at Court) and also at the insult to Sandwich's wife, to whom Pepys was deeply attached. Following a brief estrangement, friendly relations were resumed, although the two men were probably never as close again as they had been (Pepys, for example, is not mentioned in Sandwich's last will). For Pepys to raise the issue at all took considerable courage, considering how much he owed to his patron, and his Diary shows that he was strongly tempted to let the matter lie. Even when he did raise it he chose to write rather than confront Sandwich face to face. In 1668 Pepys was somewhat perturbed when his wife Elizabeth, during one of the violent quarrels which followed the discovery of his affair with her companion Deb Willet, told him that Sandwich had asked her to be his mistress. Since Pepys was in no doubt that she had refused, he decided to treat the matter as being closed, and friendly relations continued: Sandwich dined at their house for the first time a few months later. Pepys, on reflection, may have thought it possible that Elizabeth in her anger had invented the story to upset him, (as she undoubtedly invented the story that she was attending Roman Catholic services). Whatever their differences, Pepys in later life always remembered Sandwich, whom he called "that noble and unparalleled Lord", and his wife (who died in 1674) with affection and gratitude.
