"Old Trevor was evidently a man of some wealth and consideration, a J.P. and a landed proprietor. Donnithorpe is a little hamlet just to the north of Langmere, in the country of the Broads. The house was an old-fashioned, wide-spread, oak-beamed, brick building, with a fine lime-lined avenue leading up to it. There was excellent wild duck shooting in the fens, remarkably good fishing, a small but select library, taken over, as I understood, from a former occupant, and a tolerable cook, so that it would be a fastidious man who could not put in a pleasant month there. "Trevor senior was a widower, and my friend was his only son. There had been a daughter, I heard, but she had died of diphtheria while on a visit to Birmingham. The father interested me extremely. He was a man of little culture, but with a considerable amount of rude strength both physically and mentally. He knew hardly any books, but he had travelled far, had seen much of the world, and had remembered all that he had learned. In person he was a thick-set, burly man, with a shock of grizzled hair, a brown, weather-beaten face, and blue eyes which were keen to the verge of fierceness. Yet he had a reputation for kindness and charity on the country side, and was noted for the leniency of his sentences from the bench. [Illustration: "TREVOR USED TO COME IN TO INQUIRE AFTER ME."] "One evening, shortly after my arrival, we were sitting over a glass of port after dinner, when young Trevor began to talk about those habits of observation and inference which I had already formed into a system, although I had not yet appreciated the part which they were to play in my life. The old man evidently thought that his son was exaggerating in his description of one or two trivial feats which I had performed. "'Come now, Mr. Holmes,' said he, laughing good-humouredly, 'I'm an excellent subject, if you can deduce anything from me.' "'I fear there is not very much,' I answered. 'I might suggest that you have gone about in fear of some personal attack within the last twelve months.' "The laugh faded from his lips and he stared at me in great surprise. "'Well, that's true enough,' said he. 'You know, Victor,' turning to his son, 'when we broke up that poaching gang, they swore to knife us; and Sir Edward Hoby has actually been attacked. I've always been on my guard since then, though I have no idea how you know it.' "'You have a very handsome stick,' I answered. 'By the inscription, I observed that you had not had it more than a year. But you have taken some pains to bore the head of it and pour melted lead into the hole, so as to make it a formidable weapon. I argued that you would not take such precautions unless you had some danger to fear.' "'Anything else?' he asked, smiling. "'You have boxed a good deal in your youth.' "'Right again. How did you know it? Is my nose knocked a little out of the straight?'
