period, less than a century younger than Castra Regis. The windows of the study were barred and locked, and heavy dark curtains closed them in. When this was done not a gleam of light from the tower could be seen from outside.
When they were alone, Sir Nathaniel explained that he had taken his old friend, Mr. Salton, into full confidence, and that in future all would work together.
"It is important for you to be extremely careful. In spite of the fact that our marriage was kept secret, as also your temporary absence, both are known."
"How? To whom?"
"How, I know not; but I am beginning to have an idea."
"To her?" asked Adam, in momentary consternation.
Sir Nathaniel shivered perceptibly.
"The White Worm--yes!"
Adam noticed that from now on, his friend never spoke of Lady Arabella otherwise, except when he wished to divert the suspicion of others.
Sir Nathaniel switched off the electric light, and when the room was pitch dark, he came to Adam, took him by the hand, and led him to a seat set in the southern window. Then he softly drew back a piece of the curtain and motioned his companion to look out.
Adam did so, and immediately shrank back as though his eyes had opened on pressing danger. His companion set his mind at rest by saying in a low voice:
"It is all right; you may speak, but speak low. There is no danger here--at present!"
Adam leaned forward, taking care, however, not to press his face against the glass. What he saw would not under ordinary circumstances have caused concern to anybody. With his special knowledge, it was appalling--though the night was now so dark that in reality there was little to be seen.
On the western side of the tower stood a grove of old trees, of forest dimensions. They were not grouped closely, but stood a little apart from each other, producing the effect of a row widely planted. Over the tops of them was seen a green light, something like the danger signal at a railway-crossing. It seemed at first quite still; but presently, when Adam's eye became accustomed to it, he could see that it moved as if trembling. This at once recalled to Adam's mind the light quivering above the well-hole in the darkness of that inner room at Diana's Grove, Oolanga's awful shriek, and the hideous black face, now grown grey with terror, disappearing into the impenetrable gloom of the mysterious orifice. Instinctively he laid his hand on his revolver, and stood up ready to protect his wife. Then, seeing that nothing happened, and that the light and all outside the tower remained the same, he softly pulled the curtain over the window.
Sir Nathaniel switched on the light again, and in its comforting glow they began to talk freely.
Chapter 22 - At Close Quarters
"She has diabolical cunning," said Sir Nathaniel. "Ever since you left, she has ranged along the Brow and wherever you were accustomed to frequent. I have not heard whence the knowledge of your movements came to her, nor have I been able to learn any data whereon to found an opinion. She seems to have heard both of your marriage and your absence; but I gather, by inference, that she does not actually know where you and Mimi are, or of your return. So soon as the dusk fails, she goes out on her rounds, and before dawn covers the whole ground round the Brow, and away up into the heart of the Peak. The White Worm, in her own proper shape, certainly has great facilities for the business on which she is now engaged. She can look into windows of any ordinary kind. Happily, this house is beyond her reach, if she wishes--as she manifestly does--to remain unrecognised. But, even at this height, it is wise to show no lights, lest she might learn something of our presence or absence."
"Would it not be well, sir, if one of us could see this monster in her real shape at close quarters? I am willing to run the risk--for I take it there would be no slight risk in the doing. I don't suppose anyone of our time has seen her close and lived to tell the tale."
Sir Nathaniel held up an expostulatory hand.
"Good God, lad, what are you suggesting? Think of your wife, and all that is at stake."
"It is of Mimi that I think--for her sake that I am willing to risk whatever is to be risked."
Adam's young bride was proud of
