but miscreant does not in the least suspect, a little fact of some importance, viz., that just now through a space of full three minutes he has been overlooked and studied by one, who (though reading in a dreadful book, and suffering under mortal panic) took accurate notes of so much as his limited opportunities allowed him to see, and will assuredly report the creaking shoes and the silk-mounted surtout in quarters where such little facts will tell very little to his advantage. But, although it is true that Mr. Williams, unaware of the journeyman's having 'assisted' at the examination of Mrs. Williamson's pockets, could not connect any anxiety with that person's subsequent proceedings', nor specially, therefore, with his having embarked in the rope-weaving line, assuredly he knew of reasons enough for not loitering. And yet he _did_ loiter. Reading his acts by the light of such mute traces as he left behind him, the police became aware that latterly he must have loitered. And the reason which governed him is striking; because at once it records--that murder was not pursued by him simply as a means to an end, but also as an end for itself. Mr. Williams had now been upon the premises for perhaps fifteen or twenty minutes; and in that space of time he had dispatched, in a style satisfactory to himself, a considerable amount of business. He had done, in commercial language, 'a good stroke of business.' Upon two floors, viz., the cellar-floor and the ground-floor, he has 'accounted for' all the population. But there remained at least two floors more; and it now occurred to Mr. Williams that, although the landlord's somewhat chilling manner had shut him out from any familiar knowledge of the household arrangements, too probably on one or other of those floors there must be some throats. As to plunder, he has already bagged the whole. And it was next to impossible that any arrear the most trivial should still remain for a gleaner. But the throats--the throats--there it was that arrears and gleanings might perhaps be counted on. And thus it appeared that, in his wolfish thirst for blood, Mr. Williams put to hazard the whole fruits of his night's work, and his life into the bargain. At this moment, if the murderer knew all, could he see the open window above stairs ready for the descent of the journeyman, could he witness the life- and-death rapidity with which that journeyman is working, could he guess at the almighty uproar which within ninety seconds will be maddening the population of this populous district--no picture of a maniac in flight of panic or in pursuit of vengeance would adequately represent the agony of haste with which he would himself be hurrying to the street-door for final evasion. That mode of escape was still free. Even at this moment, there yet remained time sufficient for a successful flight, and, therefore, for the following revolution in the romance of his own abominable life. He had
