nine o'clock
Among the regular visitors are at least half a dozen young men , belonging to our best families -- who have been raised with care , and well educated . That their presence here is unknown to their friends , I am quite certain -- or , at least , unknown and unsuspected by some of them . They do not drink a great deal yet ; but all try a glass or two . Toward nine o'clock , often at an earlier hour , you will see one and another of them go quietly out of the bar , through the sitting-room , preceded , or soon followed , by Green and Slade . At any hour of the night , up to one or two , and sometimes three o'clock , you can see light streaming through the rent in a curtain drawn before a particular window , which I know to be in the room of Harvey Green . These are facts , sir ; and you can draw your own conclusion . I think it a very serious matter . ''
