midnight
The officer did not come forth . When the last passers-by had returned home , when the windows of all the other houses were extinguished , Quasimodo was left entirely alone , entirely in the dark . There were at that time no lamps in the square before Notre-Dame . Meanwhile , the windows of the Gondelaurier mansion remained lighted , even after midnight . Quasimodo , motionless and attentive , beheld a throng of lively , dancing shadows pass athwart the many-colored painted panes . Had he not been deaf , he would have heard more and more distinctly , in proportion as the noise of sleeping Paris died away , a sound of feasting , laughter , and music in the Gondelaurier mansion . Towards one o'clock in the morning , the guests began to take their leave .
