Johnny looked where the boy was pointing, and, sure enough, Johnny saw his sister being escorted along the street by Mr. Blair, who had spoken to them of Mr. Moses on the train, and who had been with Fanny one day at the Fair.

"Why, ain't he all right," said John.

"Nary all right. Wusn't he helping to rob your grandad as he was a coming out of the train, and did'nt I nab his pal with the wad of stuff in his hand? He works with the feller what give yer old dad the short change."

Johnny would have started on a run after his sister but Louis said, "Hold on pard, I'm a running this. Ef your sis is all right, that feller is liable to git to travel over the road fer it. I've got it in fer that feller and you see if I don't git him pulled. I tell you if he gits your sis into one of them houses, she'll never come out alive fer she'll kill herself."

Johnny was white with fright but Louis laid his hand on Johnny's shoulder and said: "Now you watch the show."

A policeman was at the next corner and Louis walked up to him with the air of one who had a most important communication to make.

"Me name is Louis Burjois, and dis is de brudder of dat gal wot you see walkin' over dere. She is an innercent gal, which dat feller is a-tollin' of her off. He's a pickpocket, and I'm one wot kin swear to it. We want him arrested an' jugged. We'll see to all de responsibility."

"Ah, you Arabs don't take me in that way. Git out. The gal knows her biz."

By this time Louis saw that the confidence man had stopped at one of the most prepossessing houses on the street. It was also one of the vilest and most dangerous places in the city. The door-bell had been rung, and there was not a moment to lose.
