Everyone turned round. Faull rose to welcome the late arrivals. Backhouse also stood up, and stared hard at them.

The two strangers remained standing by the door, which was closed quietly behind them. They seemed to be waiting for the mild sensation caused by their appearance to subside before advancing into the room. Maskull was a kind of giant, but of broader and more robust physique than most giants. He wore a full beard. His features were thick and heavy, coarsely modelled, like those of a wooden carving; but his eyes, small and black, sparkled with the fires of intelligence and audacity. His hair was short, black, and bristling. Nightspore was of middle height, but so tough - looking that he appeared to be trained out of all human frailties and susceptibilities. His hairless face seemed consumed by an intense spiritual hunger, and his eyes were wild and distant. Both men were dressed in tweeds.

Before any words were spoken, a loud and terrible crash of falling masonry caused the assembled party to start up from their chairs in consternation. It sounded as if the entire upper part of the building had collapsed. Faull sprang to the door, and called to the servant to say what was happening. The man had to be questioned twice before he gathered what was required of him. He said he had heard nothing. In obedience to his master's order, he went upstairs. Nothing, however, was amiss there, neither had the maids heard anything.

In the meantime Backhouse, who almost alone of those assembled had preserved his sangfroid, went straight up to Nightspore, who stood gnawing his nails.

"Perhaps you can explain it, sir?"

"It was supernatural," said Nightspore, in a harsh, muffled voice, turning away from his questioner.

"I guessed so. It is a familiar phenomenon, but I have never heard it so loud."

He then went among the guests, reassuring them. By degrees they settled down, but it was observable that their former easy and good - humoured interest in the proceedings was now changed to strained watchfulness. Maskull and Nightspore took the places allotted to them. Mrs. Trent kept stealing uneasy glances at them. Throughout the entire incident, Mozart's hymn continued to be played. The orchestra also had heard nothing.
