Joan laughed at his gloomy premonitions.
“You won’t be kept on the rack much longer, that’s one good thing. There’s just this dance, then the march-past for judging the costumes, and then it will be midnight when everybody must unmask. So you’ll have to make the best of your fears in the next half-hour. After that there’ll be no excuse for them.”
“Meanwhile, on with the dance, eh?” said Sir Clinton. “I see it’s no use trying to give you a nightmare. You’re too poor a subject to repay the labour and trouble. Besides, this music’s terribly straining on the vocal cords if one tries to compete with it.”
As he spoke, however, the orchestra reached a diminuendo in the score and sank to comparative quietness. Joan looked here and there about the room as they danced and at last detected the figure for which she was searching.
“That’s Michael over there,” she pointed out, “the one dancing with the girl dressed as …”
Across the sound of the music there cut the sharp report of a small-calibre pistol fired in some adjacent room. On the heels of it came the crash and tinkle of falling glass, and, almost simultaneously, a cry for help in a man’s voice.
Sir Clinton let Joan’s hand go and turned to the door; but before he could take a step, the lights above them vanished and the room was plunged in darkness. Joan felt a hand come out and grip her arm.
“That you, Joan?”
“Yes.”
“They’ve taken out the main switch,” Sir Clinton said hurriedly. “Get hold of some man at once and show him where it is. We want the lights as quick as possible. I can trust you not to lose your head. Take a man with you for fear of trouble. We don’t know what’s happening.”
“Very well,” Joan assured him.
“Hurry!” Sir Clinton urged.
His hand dropped from her arm as he moved invisibly away towards the door. In the darkness around her she could hear movements and startled exclamations. The orchestra, after mechanically playing a couple of bars, had fallen to silence. Someone blundered into her and passed on before she could put out her hand.
“Well, at least I know where the door is,” she assured herself; and she began to move towards it.
Meanwhile the cries for help continued to come from the museum. Then, abruptly, they were hushed; and she shuddered as she thought of what that cessation might mean. She moved forward and came to what seemed an unobstructed space on the floor, over which she was able to advance freely.
Her whole senses were concentrated on reaching the exit; but her mind appeared to work independently of her own volition and to conjure up the possibilities behind this series of events. Sir Clinton had evidently expected some criminal attempt that night; and he had assumed that the museum would be the objective. But suppose he were wrong. Perhaps the affair in the museum was only a blind to draw towards it all the men outside the ballroom. Then, when they were disposed of, there might come an incursion here. Most of the women had taken advantage of their fancy dress to deck themselves out with jewellery, and a few armed men could easily reap a small fortune in a minute or two. Despite the soundness of her nerves, she began to feel anxious, and to conjure up still more appalling pictures.
Suddenly her eyes were dazzled by a flash of light as a man beside her struck a match. Almost at the same moment she felt a hand on her shoulder and she was pulled backwards so brusquely that she almost lost her balance and slipped.
“Put out that match, you fool!” said Michael’s voice. “Do you want to have these girls’ dresses in a blaze?”
The flare of the match had revealed a circle of startled faces. The room was filled with excited voices and a sound of confused movements. Over at the orchestra a music-stand fell with a clash of metal. Then, close beside her in the darkness, Joan heard a girl’s voice repeating monotonously in tones of acute fear: “What does it mean? Oh, what does it mean?”
“Much good that does anyone,” Joan muttered, contemptuously. Then, aloud, she called: “Michael!”
Before he could reply, there came a sharp exclamation in a man’s voice:
“Stand back, there! My partner’s fainted.”
The possibilities involved in a panic suddenly became all too clear in Joan’s mind. If half a dozen people lost their heads, the girl might be badly hurt.
Michael’s voice was lifted again, in a tone that would have carried through a storm at sea:
“Everybody stand fast! You’ll be trampling the girl underfoot if you don’t take care. Stand still, confound you! Pull the blinds up and throw back the curtains. It’s a moonlight night.”
There was a rustling as those nearest the windows set about the execution of his orders. Light suddenly appeared, revealing the strained faces and uneasy attitudes of the company. Joan turned to Michael.
“Come with me and put in the switch, Michael. Sir Clinton’s gone to the museum. We must get the lights on quick.”
Michael, with a word to his partner, followed his fiancée towards the door. A thought seemed to strike him just as he was leaving the room:
“Wait here, everybody, till we get the lights on again. You’ll just run risks by moving about in the dark outside. It’s nothing. Probably only a fuse blown.”
“Now then, Joan, where’s that switch?” he added as they passed out of the door.
It was pitch-dark in the rest of the house; but Joan knew her way and was able to grope along the corridors without much difficulty. As they came near the switch-box, the lights flashed up again. One of the servants appeared round a corner.
“Someone had pulled out the switch, sir,” he explained. “It took me some time to make my way to it and put it in again.”
“Stout fellow!” said Michael, approvingly.
