"It's nothing." He began again to tug at his beard, as if mechanically. "What a little upsets a man if he is in the mood." He glanced at his watch, seeming, as he did so, to make a mental calculation. "It's time that some of them were here." He paused, the remainder of his speech apparently referring to some other theme. "I hope that one can rely upon them sometimes--that one may take it that the guardians of law and order do not always blunder. I suppose that we are shadowed. I suppose, too, that they will make no movement until they have received ocular demonstration of the fact that all of them are here. What's that?"

Again there was a sudden, startling change in Mr. Pendarvon's outward bearing. Obviously his every faculty was strained in the act of listening. So far as an ordinary observer would have been able to judge there did not appear to be a sound. Yet it is not improbable that something had made itself audible to Mr. Pendarvon's unusually keen sense of hearing, because presently a slight click was heard, as it seemed, within the wall itself upon his right.

"Number one!"

Mr. Pendarvon's state of tension seemed to slightly decrease. The wall upon his right was panelled from floor to ceiling. One of the panels Mr. Pendarvon slipped aside, and, in doing so, revealed a dial-plate of peculiar construction, which apparently had some connection with electricity. On it was a prominent figure 2. Beneath it a needle made three separate strokes. A large 1 appeared. Then three more separate strokes. Then another prominent 2. On the appearance of the second 2, on Mr. Pendarvon's touching an ivory button, the whole thing performed a complete revolution, and a sound as of a gong was heard.

While the gong still continued to vibrate, a voice was heard outside the door exclaiming "Reginald!"

The announcement of the name seemed to precipitate Mr. Pendarvon back into his former condition of uneasiness.

"The man himself," he muttered. Then, by way of an afterthought, with a smile which by no means suggested mirth, "I wonder if they saw him come."

He seemed to hesitate, then, with an effort, to pull himself together.

"The honourable member should not be kept waiting."

As he made this observation to himself, with another mirthless grin, he pressed a second button, which was on the other side of the dial. Immediately the door without swung open.
