Through the rents which time and weather had wrought he saw the warm glow of daylight above, for all was ruin in the great old mill, ruin within and without. As it was with the walls of stone, and the great tower of woodwork above them, so it was with the outbuildings beyond the doorway, within which he stood. The walls remained, heavily buttressed by the hardy hands of a race of men who had understood so well the necessity for fortifying their homes against all eventualities, but the timbers of the roofs had long since fallen victims to the inclemencies of the seasons and the ruthless "North-easters" which, probably, since the time when the iron shores of Britain first emerged from beneath the waters, had beaten their relentless wings against the barrier which held up their freedom. Ruxton set his lantern on the ground and moved away to the wide doorway, which no longer possessed the remotest sign of the old wooden doors which had probably been at one time heavy enough to resist a siege. Here he drew a letter from his pocket and read it carefully over by the light of the sunset. "Dear Mr. Farlow: "I never knew your wonderful coast could be so interesting, even absorbing. I feel I owe you personal thanks for a delightful time, simply because you live--where you live. I have discovered a most wonderful spot. I say discovered, but probably you have known it from the days when you were first able to toddle about by yourself. However, I must tell you of it. It is an old, old, ruined mill, regarded by the folks on your coast as an evil place which is haunted by the spirits of the smugglers who once upon a time used it as the headquarters for their nefarious trade. But the incredible part of it is we unearthed a secret in it which has remained hidden for generations, possibly centuries. Now listen carefully and I will tell you of this secret. In the middle of the stone chamber under the mill there is the entrance to a passage which communicates with that villainous cove over which the evil eye of the old mill forever gazes. Six inches beneath the surface of the debris on the floor there is a slate slab, and, on raising this, you will discover a stone staircase which goes down, down,--follow it, and you shall see what you shall see. I have since discovered that this is the _only means of reaching the beach of the cove--unless you possess wings_. But I began this note with the intention of only telling you how much I am looking forward to seeing you again on Thursday evening at eight o'clock. I do hope you are taking full advantage of your vacation from parliamentary work, and are storing up plenty of good health upon your wonderful, wonderful moors. "Yours very sincerely, "Vita Vladimir." Ruxton refolded the letter and put it away. He understood it was the final summons to that great adventure which was to tell him of the threat overshadowing his beloved country.
