“I think you will have a visitor today,” he said. “It has happened that I have been able to do a service to the son of Mr. Cotter, a wealthy banker. I am going to dine there this evening. He asked me about my friends in London, and I mentioned that my only lady friends were you and Millicent. He asked a few questions as to where you were living, and so on, and said that his wife would have much pleasure in calling and introducing Millicent into society. As your life is very dull here, and it is clearly very desirable that Millicent should go into society, I gladly accepted the offer, and I believe that she will call today.”

“That will be very nice indeed, Mark. Millicent is not complaining, but she must have felt it very dull. I have even felt it so myself after the cheerful society we had at home.”

“I don't know that I shall like it,” Millicent said doubtfully.

“Oh, yes, you will, Millicent; and besides, it will be good for you. It is not natural for a girl of your age to be here without friends, and I shall be very glad to know that you are going to mix a little with other people.”

Mrs. Cotter called that afternoon, and three days later Mark met Mrs. Cunningham and Millicent at a dinner party at the banker's, and Mrs. Cotter introduced them very warmly to several of her friends, with the result that in a very short time they were frequently invited out, while they became very intimate with the banker and his wife, and often spent the day there.

CHAPTER XIV.

Some little time after this Mark was intrusted by his chief with the work of discovering a man who had committed a very atrocious murder, and was, it was tolerably certain, hiding in the slums of Westminster. It was the first business of the kind that had been confided to him, and he was exceedingly anxious to carry it out successfully. He dressed himself as a street hawker, and took a small lodging in one of the lanes, being away the greater portion of the day ostensibly on his business, and of an evening dropped into some of the worst public houses in the neighborhood. He was at first viewed with some suspicion, but it was not long before he became popular. He let it be understood that he had got into trouble down in the country, and that he was quite ready to take part in any job that promised to be profitable. But he principally owed his popularity to the fact that the bully of the locality picked a quarrel with him, and, to the astonishment of those present, Mark invited him to go outside.

“You had better make it up with him, mate,” a man sitting by his side whispered. “He was in the prize ring at one time, and thrashed big Mike Hartley at Kennington. He had to give it up owing to having fought a cross. He would kill you in five minutes.”

“I will chance that,” Mark said quietly, as he moved towards the door. “I don't think that he is stronger than I am, and I can use my fists a bit, too.”
