The cottage was of grey stone, a clumsy rugged-looking habitation set on the side of a purple-clothed hill, beside a grass-grown lane, which meandered down the valley. On the slope of the hill were many disused mining shafts with huge mounds of earth and ruined buildings beside them. The hilltops had been a Roman camp, and the boundaries could still be defined. In the centre and amongst many gigantic stones was a sacrificial altar of the Druids, with grooves cut in its hardness so that the blood of the victims might stream to the ground. Alice never liked this unholy hill, as she was sensitive enough to feel the influence which clung round it. But Narvaez had established his home beside the miniature mountain, because on moonless nights he could perform uncanny ceremonies on the altar, which was given over to the Dark Powers he worshipped and propitiated. Enistor had likewise taken part in these sacrilegious doings and shivered at the memory of certain things, when he sighted the sinister grey monoliths which crowned the hill. Great as was his courage, it was not entirely proof against the deadly influences of the evil beings who haunted the place, although in a lesser degree than Narvaez he could compel them to service by performing certain rites. Enistor was ushered into Don Pablo's study by the housekeeper, a brown-faced cheery old woman, too simple-minded to understand her master's weird powers. The apartment was of no great size, and the limited space was but sparsely furnished. There were only a table, which served as a desk, two chairs, a well-filled bookcase and a ponderous iron safe, wherein Narvaez stored what valuables he had by him. The walls were draped with dull red cloth, and the floor, oddly enough, was covered with a black carpet. The effect was menacing and impressive. When the visitor entered, a fire-place wherein large logs flamed faced him, while opposite the one window looking out on to the hilltop was a closed door leading to a sealed apartment, which Don Pablo allowed no one to enter into save himself and his pupil. Across the passage was a dining-room together with a tiny kitchen and a bedroom for the housekeeper at the back. The cottage itself was placed in a disorderly uncultivated garden surrounded by a loosely built stone wall. There was no upstairs, and the house being roofed with slate covered with moss presented a sombre appearance. In its greyness it resembled a huge toad squatting amongst the heather. "How can you bear a fire on this hot day?" asked Enistor, throwing himself into the vacant chair and speaking irritably. "You are in that kind of humour which seeks any outlet for its relief," was the Spaniard's irrelevant reply. "How often have I told you that it is necessary for you to get complete command of your temper. I have a fire because this body I occupy just now is nearly worn out and requires artificial heat to sustain it." "Why don't you get a new one?" demanded the visitor still crossly.
