Passing on his way to London, Sir William encountered Sir Denzil Onslow on horseback, escorted by two grooms. ‘Hereupon,’ says a pamphlet of the period, ‘the knight, as it is customary for those of the black robe (whose habit he had taken upon him) to do to Men of Figure, very courteously gave him the salute of his hat and the right hand of the road, which the said Mr. Onslow, being some time after apprised of, acknowledged to be true, with this circumstance, that he well remembered that he met a smock-faced, trim parson on such an occasion, but that his eyes were so taken up, and his attention wholly employed, with the beauties of the fine horse he rode upon, that he had no time to make a true discovery of his person at that juncture.’ [Sidenote: _UNCOURTEOUS INTERVIEW._] Wyndham, finding the pursuit grow too hot for him, rode to Sion House, Isleworth, one of the seats of his father-in-law, the Duke of Somerset. The two went up to the Duke’s town residence, Northumberland House, whence Wyndham’s brother-in-law, the Earl of Hertford, sent notice of the presence of such a guest to Secretary Stanhope. That official dispatched a messenger, by whom Wyndham was carried before the Council Board. It was said in London that he there denied all knowledge of a plot; but the Council, nevertheless, committed him to the Tower. The next day all London was astir with reporting the news that the Duke of Somerset, having been refused as bail for his son-in-law, had at once resigned his office of Master of the Horse. Before Wyndham surrendered, the carriage of the Duke of Somerset, his father-in-law, was seen standing at the door of the famous lawyer, Sir Edward Northey. After the surrender, Government suspected that this interview was for the purpose of a consultation as to whether the proofs against Sir William could convict him of treason. Ministers resolved that the Duke should be deprived of his places, and Lord Townshend called upon him, with a sorrowful air, and a message from the king that his Majesty had no further occasion for the Duke’s services. ‘Pray, my Lord,’ said Somerset, ‘what is the reason of it?’ Lord Townshend answered, ‘I do not know!’ ‘Then,’ said the Duke, ‘by G――, my Lord, you lie!’ ‘You know that the king puts me out for no other cause, but for the lies which you, and such as you, have invented and told of me!’ Such were the amenities which passed between noblemen in those stirring Jacobite times. The duke asked leave to wait upon the king, but he was curtly told to wait till he was sent for. [Sidenote: _A GENERAL STIR._]
