“What makes you think that?”

“T’ink! Why, I can tell dem by deir eyes and deir feet, and de whole of dem. I could pick out a fly cop from a bunch of a t’ousand. He’s sure a ’nough ‘sleut’ all right, all right. I seen him rubbering at you, boss.”

“At me! Why at me? Why, of course, I see now. Our friend McEachern has got him in to spy on us.”

“Dat’s right, boss.”

“Of course you may be mistaken.”

“Not me, boss. And, say, he ain’t de only one.”

“What, more detectives? They’ll have to put up ‘House Full’ boards at this rate. Who’s the other?”

“A mug what’s down in de soivants’ hall. I wasn’t so sure of him at foist, but now I’m on to his curves. He’s a sleut all right. He’s vally to Sir Tummas, dis second mug is; but he ain’t no vally! He’s come to see no one don’t get busy wit de jools. Say, what do youse t’ink of dem jools, boss?”

“Finest I ever saw.”
