On Mr. Wraxall's return to the inn, Mantel, the queen's valet, came to him. Mr. Wraxall gave him, in consequence of the order he brought, the letter of the Danish nobility to George III., and also a letter from himself, addressed to the queen, containing the heads of the instructions with which he was charged. It was afterwards fixed, between Baron von Seckendorf and Mr. Wraxall, that, on Saturday morning, March 25, as soon as the hereditary princess had returned to Brunswick, Mr. Wraxall should be brought to the castle, where the queen would be ready to receive him. But, after mature deliberation, the baron thought that it would be safer for him to repair to the castle during the night before the princess left Celle. The circumstance of her then being at Celle was favourable, because no one would be tempted to suppose that the queen could venture on so hazardous an experiment when her sister was under the same roof. It was therefore agreed, that precisely at eight o'clock on the evening of the 24th, Mr. Wraxall should wrap himself in his great-coat, and proceed to the entrance of the drawbridge over the great moat of the castle, where Mantel should punctually meet him, and conduct him to the queen.

I waited in this unpleasant predicament a full quarter of an hour, anxious and impatient to the greatest degree. At length Mantel came. He said not a word to me, but, wrapping his cloak all over me, and covering me with his umbrella, he led me in silence over the drawbridge, under the arch, into the square court of the castle. We went up a private staircase, and he conducted me along the great gallery or corridor into the queen's library. Two candles were burning, and the book-cases were thrown open, as it was uncertain at what hour the queen could come to me. Mantel left me, but returned in less than a quarter of an hour with a note from Baron von Seckendorf, to the following effect:--
