A tall, thin figure, curiously angular and bony, had emerged through a gap in the hedge of laurels. In his hand he held a spud, and he wore gauntleted gardener's gloves. A broad-brimmed, grey hat cast his face into shadow, but it struck me as exceedingly austere, with an ill-nourished beard and harsh, irregular features. The fly pulled up and Lord Linchmere sprang out. "My dear Thomas, how are you?" said he, heartily. But the heartiness was by no means reciprocal. The owner of the grounds glared at me over his brother-in-law's shoulder, and I caught broken scraps of sentences--"well-known wishes ... hatred of strangers ... unjustifiable intrusion ... perfectly inexcusable." Then there was a muttered explanation, and the two of them came over together to the side of the fly. "Let me present you to Sir Thomas Rossiter, Dr. Hamilton," said Lord Linchmere. "You will find that you have a strong community of tastes." I bowed. Sir Thomas stood very stiffly, looking at me severely from under the broad brim of his hat. "Lord Linchmere tells me that you know something about beetles," said he. "What do you know about beetles?" "I know what I have learned from your work upon the coleoptera, Sir Thomas," I answered. "Give me the names of the better-known species of the British scarabaei," said he. I had not expected an examination, but fortunately I was ready for one. My answers seemed to please him, for his stern features relaxed. "You appear to have read my book with some profit, sir," said he. "It is a rare thing for me to meet anyone who takes an intelligent interest in such matters. People can find time for such trivialities as sport or society, and yet the beetles are overlooked. I can assure you that the greater part of the idiots in this part of the country are unaware that I have ever written a book at all--I, the first man who ever described the true function of the elytra. I am glad to see you, sir, and I have no doubt that I can show you some specimens which will interest you." He stepped into the fly and drove up with us to the house, expounding to me as we went some recent researches which he had made into the anatomy of the lady-bird. I have said that Sir Thomas Rossiter wore a large hat drawn down over his brows. As he entered the hall he uncovered himself, and I was at once aware of a singular characteristic which the hat had concealed. His forehead, which was naturally high, and higher still on account of receding hair, was in a continual state of movement. Some nervous weakness kept the muscles in a constant spasm, which sometimes produced a mere twitching and sometimes a curious rotary movement unlike anything which I had ever seen before. It was strikingly visible as he turned towards us after entering the study, and seemed the more singular from the contrast with the hard, steady, grey eyes which looked out from underneath those palpitating brows.
