“It is really two days since you had the letter. We should have acted before this. You have no further evidence, I suppose, than that which you have placed before us - no suggestive detail which might help us?”

“There is one thing,” said John Openshaw. He rummaged in his coat pocket, and, drawing out a piece of discoloured, blue-tinted paper, he laid it out upon the table. “I have some remembrance,” said he, “that on the day when my uncle burned the papers I observed that the small, unburned margins which lay amid the ashes were of this particular colour. I found this single sheet upon the floor of his room, and I am inclined to think that it may be one of the papers which has, perhaps, fluttered out from among the others, and in that way has escaped destruction. Beyond the mention of pips, I do not see that it helps us much. I think myself that it is a page from some private diary. The writing is undoubtedly my uncle’s.”

Holmes moved the lamp, and we both bent over the sheet of paper, which showed by its ragged edge that it had indeed been torn from a book. It was headed, “March, 1869,” and beneath were the following enigmatical notices:

4th. Hudson came. Same old platform.

7th. Set the pips on McCauley, Paramore, and John Swain, of St. Augustine.

9th. McCauley cleared.

10th. John Swain cleared.

12th. Visited Paramore. All well.

“Thank you!” said Holmes, folding up the paper and returning it to our visitor. “And now you must on no account lose another instant. We cannot spare time even to discuss what you have told me. You must get home instantly and act.”

“What shall I do?”

“There is but one thing to do. It must be done at once. You must put this piece of paper which you have shown us into the brass box which you have described. You must also put in a note to say that all the other papers were burned by your uncle, and that this is the only one which remains. You must assert that in such words as will carry conviction with them. Having done this, you must at once put the box out upon the sundial, as directed. Do you understand?”

“Entirely.”

“Do not think of revenge, or anything of the sort, at present. I think that we may gain that by means of the law; but we have our web to weave, while theirs is already woven. The first consideration is to remove the pressing danger which threatens you. The second is to clear up the mystery and to punish the guilty parties.”

“I thank you,” said the young man, rising and pulling on his overcoat. “You have given me fresh life and hope. I shall certainly do as you advise.”

“Do not lose an instant. And, above all, take care of yourself in the meanwhile, for I do not think that there can be a doubt that you are threatened by a very real and imminent danger. How do you go back?”

“By train from Waterloo.”

“It is not yet nine. The streets will be crowded, so I trust that you may be in safety. And yet you cannot guard yourself too closely.”

“I am armed.”

“That is well. To-morrow I shall set to work upon your case.”

“I shall see you at Horsham, then?”

“No, your secret lies in London. It is there that I shall seek it.”

“Then I shall call upon you in a day, or in two days, with news as to the box and the papers. I shall take your advice in every particular.” He shook hands with us and took his leave. Outside the wind still screamed and the rain splashed and pattered against the windows. This strange, wild story seemed to have come to us from amid the mad elements - blown in upon us like a sheet of sea-weed in a gale - and now to have been reabsorbed by them once more.
