"A greater distance to travel."
"But the letter had also a greater distance to come."
"Then I do not see the point."
"There is at least a presumption that the vessel in which the man or men are is a sailing-ship. It looks as if they always sent their singular warning or token before them when starting upon their mission. You see how quickly the deed followed the sign when it came from Dundee. If they had come from Pondicherry in a steamer they would have arrived almost as soon as their letter. But as a matter of fact seven weeks elapsed. I think that those seven weeks represented the difference between the mail-boat which brought the letter, and the sailing-vessel which brought the writer."
"It is possible."
"More than that. It is probable. And now you see the deadly urgency of this new case, and why I urged young Openshaw to caution. The blow has always fallen at the end of the time which it would take the senders to travel the distance. But this one comes from London, and therefore we cannot count upon delay."
"Good God!" I cried; "what can it mean, this relentless persecution?"
"The papers which Openshaw carried are obviously of vital importance to the person or persons in the sailing-ship. I think that it is quite clear that there must be more than one of them. A single man could not have carried out two deaths in such a way as to deceive a coroner's jury. There must have been several in it, and they must have been men of resource and determination. Their papers they mean to have, be the holder of them who it may. In this way you see K. K. K. ceases to be the initials of an individual, and becomes the badge of a society."
"But of what society?"
"Have you never—" said Sherlock Holmes, bending forward and sinking his voice—"have you never heard of the Ku Klux Klan?"
