Observers less interested than Lanyard was then have been known feelingly to comment upon the impish trick houses frequently practice of keeping their own counsel: the shrewdest reader of façades would have gathered nothing informing from the aspect worn that night by the dwelling of Folly McFee, no clue as to whether its pretty resident were at home, or, if at home, alone . . .
Lanyard hazarded a saunter past on the sidewalk opposite. Under more direct scrutiny the house remained as little communicative, the only profit he had of the maneuvre was the assurance that nobody was skulking in any of the areaways over across from it, on the watch for the likes of himself. But then there was no conceivable reason why anybody should be; not even his most impassioned ill-wisher, much less an unimaginative police force, could have been expected to divine that any attraction could possibly draw this putative criminal back to haunt the scene of his alleged crime.
Lanyard nevertheless, on gaining the Park avenue corner, merely crossed the street and continued his stroll through the next to the north, passing on the way the gaping foundation pit observed the night before from the windows of Folly's study, a survey of which from this new angle confirmed his belief that the thief need not have found it difficult to make his way into the backyard and swarm up to the roof of the extension. On the other hand, this aspect of the premises afforded Lanyard no least twinge of guilty reminiscence. Another circumstance that proved nothing; if his personal acquaintance with downright drunkenness was limited, he knew too well that it was quite possible for one to drink oneself into a state of alcoholic insanity and retain, on coming out of it, no memory of one's performances while in that condition.
Circumnavigation of the block having brought him again into the street upon which the McFee residence faced, but this time on its northern sidewalk, Lanyard's pace slackened; and idlest insouciance masked the surge of acute interest in him when, at twenty paces' distance, he saw the iron gate to its service entrance swing open and a maid emerge and make briskly off toward Park avenue--a tidy figure in black dress, white apron and cap, taking letters to post at the corner letter-box in time for the last collection.
