While residing at Nyon Fletcher was visited by his friend and former medical adviser, William Perronet, son of the venerable Vicar of Shoreham. The Perronet family was of Swiss origin, and about this time it came to the knowledge of Mr. Perronet that he had some claim to a property situated at Chateau d'Oex, a small town in a mountain valley, about twenty miles from the north-eastern shore of the Lake of Geneva, and nearly sixty from Nyon. Fletcher assisted his friends by making inquiries and obtaining legal advice, and it was thought necessary that William Perronet should go over to press the claim in person. This he accordingly did, and, it may be said here, with complete success, though he did not live to enjoy the possession, as he was taken ill on his way home, and died before reaching England. Fletcher wrote, inviting him to be his guest: "This is a delightful country. If you come to see it, and to claim the estate, bring all the papers and letters you can collect; and share a pleasant apartment, and one of the finest prospects in the world, in the house where I was born." Soon after Mr. Perronet's arrival, it was thought necessary that he should visit Chateau d'Oex, and although it was now December, Fletcher accompanied him. The journey was not without danger, more especially for one in such a feeble state of health. It is described, together with many interesting details of Fletcher's life at Nyon, in Mr. Perronet's letters. "On Friday, the 11th, I reached Nyon, where I had the pleasure of finding our dear friend in pretty good health and spirits. Mr. Fletcher's house is a fine, large building, agreeably situated. It is in the form of a castle, and is supposed to have been built five hundred years ago.... "His chief delight seems to be in the meeting of his little society of children; and as he is exceedingly fond of them, they appear to be altogether as fond of him. He seldom either walks abroad or rides out, but some of them follow him, singing the hymns they have learned, and conversing with him by the way. But you must not suppose that he is permitted to enjoy this happiness unmolested. Not only the drunkards make songs upon him and his little companions, but many of the clergy loudly complain of such irregular proceedings."
