I didn't get it at first, and then when I did I walked back and there were noises | in the house as if there was a fight going on.' "

Simon nodded a number of times with the gravest respect.

"I can see that I shouldn't have underestimated your public," he drawled. "They come from a very talented class. They know' just whose house they're passing on any street in town. With their catlike eyes, they can recognise characters like me in dark corners in a dimout. They can tell at a glance whether I'm trying to break in, or whether I'm just looking for the bell or the right key. And of course they know that you're the only officer in New York to call out on a case like that. They wouldn't dream of losing face by just mentioning it to the first cop they met on his beat."
