Theodoric Voler had been brought up, from infancy to the confines of middle age, by a fond mother whose chief solicitude had been to keep him screened from what she called the coarser realities of life. When she died she left Theodoric alone in a world that was as real as ever, and a good deal coarser than he considered it had any need to be. To a man of his temperament and upbringing even a simple railway journey was crammed with petty annoyances and minor discords, and as he settled himself down in a second-class compartment one September morning he was conscious of ruffled feelings and general mental discomposure. He had been staying at a country vicarage, the inmates of which had been certainly neither brutal nor bacchanalian, but their supervision of the domestic establishment had been of that lax order which invites disaster. The pony carriage that was to take him to the station had never been properly ordered, and when the moment for his departure drew near the handy-man who should have produced the required article was nowhere to be found. In this emergency Theodoric, to his mute but very intense disgust, found himself obliged to collaborate with the vicar’s daughter in the task of harnessing the pony, which necessitated groping about in an ill-lighted outhouse called a stable, and smelling very like one—except in patches where it smelt of mice. Without being actually afraid of mice, Theodoric classed them among the coarser incidents of life, and considered that Providence, with a little exercise of moral courage, might long ago have recognised that they were not indispensable, and have withdrawn them from circulation. As the train glided out of the station Theodoric’s nervous imagination accused himself of exhaling a weak odour of stable-yard, and possibly of displaying a mouldy straw or two on his usually well-brushed garments. Fortunately the only other occupant of the compartment, a lady of about the same age as himself, seemed inclined for slumber rather than scrutiny; the train was not due to stop till the terminus was reached, in about an hour’s time, and the carriage was of the old-fashioned sort, that held no communication with a corridor, therefore no further travelling companions were likely to intrude on Theodoric’s semi-privacy. And yet the train had scarcely attained its normal speed before he became reluctantly but vividly aware that he was not alone with the slumbering lady; he was not even alone in his own clothes. A warm, creeping movement over his flesh betrayed the unwelcome and highly resented presence, unseen but poignant, of a strayed mouse, that had evidently dashed into its present retreat during the episode of the pony harnessing. Furtive stamps and shakes and wildly directed pinches failed to dislodge the intruder, whose motto, indeed, seemed to be Excelsior; and the lawful occupant of the clothes lay back against the cushions and
