“And our friend out there?” said he. “Is he one of those whom you have described?”

“I was just coming to him,” replied Colonel Knight, raising a shaking hand to his forehead and mopping off the beaded perspiration. “That is ‘Billy the Strangler,’ and I think the ‘Kid’ is with him. Those were my Apaches—my gun men—my killers. They are much alike. Both have cunning of a low order; and persistence—they are like bloodhounds, once they are put on the trail.

“There remains but one,” he said hoarsely. “That is Louie Martin, my gem expert. Martin is one of the best judges of diamonds and pearls in the world. He is an expert in recutting and remounting stolen jewelry. And he has a wide acquaintance among the crooked dealers of this country and Europe—”
