The first warning had been given by the gong when Shorty returned and reported the road clear, and the two took their way to the next street, where they ascended a common stair, and by standing on the railing at the top managed to reach the hatch leading to the roof, by Shorty climbing up on The Fin’s shoulders and then pulling his helper up as soon as he had forced the hatch and reached the low den between that and the slates. There was another hatch yet to force—that which led out on to the slates—and to reach that the two had to crawl along in a stooping position, carefully feeling with their feet for the cross beams lest they should suddenly plunge through the lath and plaster into the room below. In crawling along thus they felt and passed the water cistern which supplied the whole tenement beneath them, which stood as close in under the slope of the roof as its height would admit of. Getting open the upper hatch proved no difficult task, and then they tossed up who should get out and make his way along the housetops to the major’s house. The lot fell to Shorty, and he got out and patiently worked his way along the slates and over ranges of chimney cans to the more aristocratic street hard by. When he reached the attic windows of the major’s house he looked at his watch and decided that the whole household and all the guests must then be busy downstairs, the dinner in full swing, and the servants too excited and flurried to think of coming near the bedrooms or upper flats. One of the attics, presumably occupied by the servants, had its window open, and Shorty had merely to raise the sash a little higher to pass within and have the free range of the whole of the house but the area and first flat.
