He had not long to wait, for there came the distant sound of screaming and fighting. It came nearer and nearer, till at last, with a resounding crash, the picture over the panelled door came down with shattered glass and broken frame, the door swung open noiselessly and easily, and in the aperture stood the flushed and triumphant figure of Mr. Narkom.
