"Have you got a window we can watch it from?"
Mr. Moon turned ponderously round and without a word led the way to the first floor, puffing enormously on the stairs.
"You can see it from the club-room," he said at length, "but this 'ere little place is better."
He pushed open a door, and we entered a small sitting-room. "That's the place," he said, pointing. "There's a new packing-case a-standing outside now."
Norbury Row presented an appearance common enough in parts of the city a little way removed from the centre. A street of houses that once had sheltered well-to-do residents had gradually sunk in the world to the condition of tenement-houses, and now was on the upward grade again, being let in floors to the smaller sort of manufacturers, and to such agents and small commercial men as required cheap offices. No. 8 was much like the rest. A packing-case maker had the ground-floor, as Moon had said, and a token of his trade, in the shape of a new packing-case, stood on the pavement. The rest of the building showed nothing distinctive.
"There y'are, gents," said Mr. Moon, "if you want to watch, you're welcome, bein' the p'lice, which I allus does my best for, allus. But you'll have to excuse me now, 'cos o' the bar."
Mr. Moon stumped off downstairs, leaving Plummer and myself watching at the window.
"Your friend the publican seems very proud of helping the police," I remarked.
Plummer laughed. "Yes," he said, "or at any rate, he is anxious we shan't forget it. You see, it's in some way a matter of mutual accommodation. We make things as easy as possible for him on licensing days, and as he has a pretty extensive acquaintance among the sort of people we often want to get hold of, he has been able to show his gratitude very handsomely once or twice."
The house on which our eyes were fixed was a little too far up the street for us to see perfectly through the window of the second-floor, though we could see enough to indicate that it was furnished as an office. We agreed that the unknown second-floor tenant was more likely to be our customer, or connected with him, than either of the others. Still, we much desired a nearer view, and presently, since the coast seemed clear, Plummer announced his intention of taking one.
