Nick met two men dashing down the stairs, the first one of whom he struck in the face with the butt of his revolver, knocking him senseless, and grappled with the other. Patsy had sprung at the servant woman, who had shown fight, to find she was a man in woman’s clothes, and he found his hands full. Chick had easy work in overcoming the Brown Robin. It was a fight soon over, however. The two men Nick had attacked in the hall, finding the door open, fled through it. The other man, in woman’s clothes, was overcome by Patsy, and, with Nick’s aid, bound. Though beaten, the Brown Robin was game. “Well, Mr. Carter,” she said, “I have come to the end. I was told you would overreach me if I met you. You have. I did not think you would. I thought myself smarter than you.” “You were very easy,” said Nick, quietly. “I could have taken you yesterday, when I dined with you, in the Lexington Avenue house, as Mr. Cary.” “You?” she cried. “You did that?” “Oh, yes, Mrs. Clymer. You do not offer your cheek to me to-day.” He imitated perfectly Mr. Cary’s voice. This was too much for the Brown Robin. She seemed to feel worse over this deception than over her arrest and defeat. Nick saw that she had been wounded in her conceit. Finally she said: “Well, if I am no better than that, I deserve to fail. Lock me up.” The Brown Robin and her servant were taken to the station house and locked up. “Your imitation of me,” said Mr. Mountain to Chick, “was so good that when I passed behind that safe and saw you there waiting for me I was startled, though I expected to find you there. It was capitally done. I congratulate you.” “Congratulate the chief, Mr. Mountain. It was his play from start to finish, and he made me up.” The compromising photographs of Mr. Cary, together with the plate, were easily recovered in the house in which they were taken. Nick’s inquiries into the life of the Brown Robin showed that she had been engaged in a criminal career almost from the moment that she had eloped with the man Stymers from Mr. Mountain’s employ, though at one time she had been on the stage and at another time a newspaper writer. Stymers was a bank burglar, who had led her into crime. Her criminal career had been most successful, and the first check called in it was when she met Nick Carter and his faithful band. She received a long sentence, and it is hardly likely that she will ever again embark on a career of wickedness. CHAPTER XI. AT THE DOG SHOW. Next day was “blue Monday” with Nick, and he decided to try the Dog Show at Madison Square Garden as a cure for the “dumps.” After luncheon he set out to visit the Garden, little dreaming what fresh adventures were in store for him as the result of that visit.
