Only on one occasion after this do we find mention of Mary Livingston in connection with her royal mistress. It is on the day following the Queen's surrender at Carberry, when she was brought back a prisoner to Edinburgh. The scene is described by Du Croc, the French Ambassador. "On the evening of the next day," he writes in the official report forwarded to his court, "at eight o'clock, the Queen was brought back to the castle of Holyrood, escorted by three hundred arquebusiers, the Earl of Morton on the one side, and the Earl of Athole on the other; she was on foot, though two hacks were led in front of her; she was accompanied at the time by Mademoiselle de Sempel and Seton, with others of her chamber, and was dressed in a night-gown of various colours."[90] After the Queen's removal from Edinburgh the Sempills also left it to reside sometimes at Beltreis, and sometimes at Auchtermuchty, but chiefly in Paisley, where they built a house which was still to be seen but a few years ago, near what is now the Cross. Their retirement from the capital did not, however, secure for them the quietness which they expected to enjoy. They had stood too high in favour with the captive Queen to be overlooked by her enemies. The Regent Lennox, remembering that Mary Livingston had been entrusted with the care of the royal jewels and wardrobe, accused her of having some of the Queen's effects in her possession. Notwithstanding her denial, her husband was arrested and cast into prison, and she herself brought before the Lords of the Privy Council. Their cross-questioning and brow-beating failed to elicit any information from her, and it was only when Lennox threatened to "put her to the horn", and to inflict the torture of the "boot" on her husband, that she confessed to the possession of "three lang-tailit gowns garnished with fur of martrix and fur of sables". She protested, however, that, as was indeed highly probable, these had been given to her, and were but cast-off garments, of little value or use to anyone. In spite of this, she was not allowed to depart until she had given surety "that she would compear in the council-chamber on the morrow and surrender the gear". Lennox's death, which occurred shortly after this, did not put an end to the persecution to which the Sempills were subjected. Morton was as little friendly to them as his predecessor had been. He soon gave proof of this by calling upon John Sempill to leave his family and to proceed to England, as one of the hostages demanded as security for the return of the army and implements of war, sent, under Sir William Drury, to lay siege to Edinburgh Castle.
