Such thoughts as these flashed through Hackness's mind as he stood under the portico of the Lyceum Theatre, quite helpless and inert for the moment.

But the darkness was thicker and blacker than anything he had ever imagined. It was absolutely the darkness that could be felt. Hackness could hear the faint scratching of matches all around him, but there was no glimmer of light anywhere. And the atmosphere was thick, stifling, greasy. Yet it was not quite as stifling as perfervid imagination suggested. The very darkness suggested suffocation. Still, there was air, a sultry light breeze that set the murk in motion, and mercifully brought from some purer area the oxygen that made life possible. There was always air, thank God, to the end of the Four Days' Night.

Nobody spoke for a time. Not a sound of any kind could be heard. It was odd to think that a few miles away the country might be sleeping under the clear stars. It was terrible to think that hundreds of thousands of people must be standing lost in the streets and yet near to home.

A little way off a dog whined, a child in a sweet refined voice cried that she was lost. An anxious mother called in reply. The little one had been forgotten in the first flood of that awful darkness. By sheer good luck Hackness was enabled to locate the child. He could feel that her wraps were rich and costly, though the same fatty slime was upon them. He caught the child up in his arms and yelled that he had got her. The mother was close by, yet full five minutes elapsed before Hackness blundered upon her. Something was whining and fawning about his feet.

He called upon Grimfern, and the latter answered in his ear. Cynthia was crying pitifully and helplessly. Some women there were past that.

"For Heaven's sake tell us what we are to do," Grimfern gasped. "I flatter myself that I know London well, but I couldn't find my way home in this."

Something was licking Hackness's hand. It was the dog Kim. There was just a chance here. He tore his handkerchief in strips and knotted it together. One end he fastened to the little dog's collar.

"It's Kim," he explained. "Tell the dog 'home.' There's just a chance that he may lead you home. We're very wonderful creatures, but one sensible dog is worth a million of us to-night. Try it."

"And where are you going?" Cynthia asked. She spoke high, for a babel of voices had broken out. "What will become of you?"

"Oh, I am all right," Hackness said with an affected cheerfulness. "You see, I was fairly sure that this would happen sooner or later. So I pigeon-holed a way of dealing with the difficulty. Scotland Yard listened, but thought me a bore all the same. This is the situation where I come in."
