Listen and watch and through the tumult, rising like a strange incense from the smear of bodies, tables and waiters, will come the curious thing that is never contained in the vice reports. The gleam of the devil himself--the echo of some mystic cymbal note. Later the music will let out a tinny blaze of sound. Men and women will press together and a pack of bodies will sway on the dance floor. The tungstens will go out and the spotlight will throw colors--green, purple, lavender, blue, violet--and as the scene grows darker and the colors revolve a howl will fill the place. But on the dance floor a silence will fasten itself over the swaying bodies and there will be only the sound of feet pushing. The silence of a ritual--faces stiffened, eyes rolling--a rigid embrace of men and women creeping cunningly among the revolving colors and the whiplike rhythms of the jazz band. * * * * * "Lost souls," says the vice reports, and the vice reports speak with a calm and knowing voice. Women whose bodies and faces are like shells of evil; vicious seeming men with a rasp in their laughter. These are among those present. Aphrodite is a blousy wench in the 35th and State streets neighborhood. And her votaries, although they offer an impressive ensemble, are a sorry lot taken face by face. Izzy, who is an old timer, sits at a table and takes it in. Izzy's eyes and ears have learned to pick details in a bedlam. He can talk softly and listen easily through the height of the cabaret racket. The scene hits Izzy as water hits a duck's back. "Well," he says, "it's a good night tonight. The slummers are out in full force rubberin' at each other. Well, this is a funny world, take it from me. Me? Huh, I come here every night or so to have a little drink and look 'em over for a while. Ain't nothing to see but a lot o' molls and a lot of sucker guys. Them? Say, they never learn no better. Tough guys ain't no different from soft guys, see? They all fall for the dames just as hard and just as worse. There's many a good guy in this place that's been gave a tumble by them, see? "There, I got an idee he'd blow in tonight. He ain't missed a Saturday night for months. And he usu'lly makes it four or five times a week. That guy over there wit' the mop o' gray hair. Yeah, that's him. Well, he's the professor. I spotted him in the district a year or so ago. He had a dame wit' him who I know, see? A terrible broad. Say, maybe you've heard of him. His name is Weintraub. I picked it up from the dame he's goin' wit', see? He ought to be in your line. He was a reg'lar music professor before he come down. The leader of a swell orchestra somewhere in the east or in Europe, I guess. The dame don't know for sure, but she told me he was some baby on music.
