Mrs. Opimian was domestic. The care of the doctor had supplied her with the best books on cookery, to which his own inventive genius and the kindness of friends had added a large, and always increasing manuscript volume. The lady studied them carefully, and by diligent superintendence left the doctor nothing to desire in the service of his table. His cellar was well stocked with a selection of the best vintages, under his own especial charge. In all its arrangements his house was a model of order and comfort; and the whole establishment partook of the genial physiognomy of the master. From the master and mistress to the cook, and from the cook to the torn cat, there was about the inhabitants of the vicarage a sleek and purring rotundity of face and figure that denoted community of feelings, habits, and diet; each in its kind, of course, for the doctor had his port, the cook her ale, and the cat his milk, in sufficiently liberal allowance. In the morning while Mrs. Opimian found ample occupation in the details of her household duties and the care of her little family, the doctor, unless he had predestined the whole day to an excursion, studied in his library. In the afternoon he walked; in the evening he dined; and after dinner read to his wife and family, or heard his children read to him. This was his home life. Now and then he dined out; more frequently than at any other place with his friend and neighbour, Mr. Gryll, who entirely sympathised with him in his taste for a good dinner. Beyond the limits of his ordinary but within those of his occasional range was a solitary round tower on an eminence backed with wood, which had probably in old days been a landmark for hunters; but having in modern days no very obvious use, was designated, as many such buildings are, by the name of The Folly. The country people called it 'The Duke's Folly,' though who the Duke in question was nobody could tell. Tradition had dropped his name. One fine Midsummer day, with a southerly breeze and a cloudless sky, the doctor, having taken an early breakfast, in the progress of which he had considerably reduced the altitude of a round of beef, set out with a good stick in his hand and a Newfoundland dog at his heels for one of his longest walks, such as he could only take in the longest days.
