“Unfortunately I cannot put it more plainly, for I do not myself know what turn matters may take. You may be sure, however, that you will not be asked to do anything which your conscience does not approve; and I promise you that, when all is over, you will be proud to have been concerned in so good a work.” “If it ends happily,” said the lady. “Exactly; if it ends happily,” his lordship repeated. “And terms?” I asked. “Twenty pounds a day.” I was amazed at the sum, and must have showed my surprise upon my features. “It is a rare combination of qualities, as must have struck you when you first read the advertisement,” said Lord Linchmere; “such varied gifts may well command a high return, and I do not conceal from you that your duties might be arduous or even dangerous. Besides, it is possible that one or two days may bring the matter to an end.” “Please God!” sighed his sister. “So now, Dr. Hamilton, may I rely upon your aid?” “Most undoubtedly,” said I. “You have only to tell me what my duties are.” “Your first duty will be to return to your home. You will pack up whatever you may need for a short visit to the country. We start together from Paddington Station at 3.40 this afternoon.” “Do we go far?” “As far as Pangbourne. Meet me at the bookstall at 3.30. I shall have the tickets. Good-bye, Dr. Hamilton! And, by the way, there are two things which I should be very glad if you would bring with you, in case you have them. One is your case for collecting beetles, and the other is a stick, and the thicker and heavier the better.” * * * * * You may imagine that I had plenty to think of from the time that I left Brook Street until I set out to meet Lord Linchmere at Paddington. The whole fantastic business kept arranging and re-arranging itself in kaleidoscopic forms inside my brain, until I had thought out a dozen explanations, each of them more grotesquely improbable than the last. And yet I felt that the truth must be something grotesquely improbable also. At last I gave up all attempts at finding a solution, and contented myself with exactly carrying out the instructions which I had received. With a hand valise, specimen-case, and a loaded cane, I was waiting at the Paddington bookstall when Lord Linchmere arrived. He was an even smaller man than I had thought—frail and peaky, with a manner which was more nervous than it had been in the morning. He wore a long, thick travelling ulster, and I observed that he carried a heavy blackthorn cudgel in his hand. “I have the tickets,” said he, leading the way up the platform. “This is our train. I have engaged a carriage, for I am particularly anxious to impress one or two things upon you while we travel down.”
