Suddenly they released his hands and he heard the voice of the mother cry that it was time, and they must go. Which way they went he did not pause to see. He only realised that he was free, and he blundered through the darkness till he found the stairs and then tore up them to his room as though all hell was at his heels.

He flung himself on the sofa, with his face in his hands, and groaned. Swiftly reviewing a dozen ways of immediate escape, all equally impossible, he finally decided that the only thing to do for the moment was to sit quiet and wait. He must see what was going to happen. At least in the privacy of his own bedroom he would be fairly safe. The door was locked. He crossed over and softly opened the window which gave upon the courtyard and also permitted a partial view of the hall through the glass doors.

As he did so the hum and murmur of a great activity reached his ears from the streets beyond—the sound of footsteps and voices muffled by distance. He leaned out cautiously and listened. The moonlight was clear and strong now, but his own window was in shadow, the silver disc being still behind the house. It came to him irresistibly that the inhabitants of the town, who a little while before had all been invisible behind closed doors, were now issuing forth, busy upon some secret and unholy errand. He listened intently.

At first everything about him was silent, but soon he became aware of movements going on in the house itself. Rustlings and cheepings came to him across that still, moonlit yard. A concourse of living beings sent the hum of their activity into the night. Things were on the move everywhere. A biting, pungent odour rose through the air, coming he knew not whence. Presently his eyes became glued to the windows of the opposite wall where the moonshine fell in a soft blaze. The roof overhead, and behind him, was reflected clearly in the panes of glass, and he saw the outlines of dark bodies moving with long footsteps over the tiles and along the coping. They passed swiftly and silently, shaped like immense cats, in an endless procession across the pictured glass, and then appeared to leap down to a lower level where he lost sight of them. He just caught the soft thudding of their leaps. Sometimes their shadows fell upon the white wall opposite, and then he could not make out whether they were the shadows of human beings or of cats. They seemed to change swiftly from one to the other. The transformation looked horribly real, for they leaped like human beings, yet changed swiftly in the air immediately afterwards, and dropped like animals.

The yard, too, beneath him, was now alive with the creeping movements of dark forms all stealthily drawing towards the porch with the glass doors. They kept so closely to the wall that he could not determine their actual shape, but when he saw that they passed on to the great congregation that was gathering in the hall, he understood that these were the creatures whose leaping shadows he had first seen reflected in the windowpanes opposite. They were coming from all parts of the town, reaching the appointed meeting-place across the roofs and tiles, and springing from level to level till they came to the yard.
