"Oh, we must have Bates in this, by all means. Perhaps you would not mind leaving a message as you go along, and ask him to be good enough to call here not later than nine to-morrow morning. I think I can promise Inspector Bates that his time with me will not be wasted. And now, if you must go----"

Rigby took the hint and departed. He left the message for Bates, who, he was informed, might not be at the office the whole of the next day. This being so, Rigby rose early, and made his way to Shannon Street police station directly after breakfast. He was fortunate enough to catch Bates, who appeared to be in a tremendous hurry. He had five minutes to spare, he explained, but a quarter of an hour had elapsed before Bates rose and rang his bell.

"The other business must wait," he said. "Important as it is, I will go and call on Seymour at once."

[CHAPTER XLIV.]

THE SUBSTITUTE.

It was nearly eleven o'clock before Bates reached Seymour's rooms. He listened patiently to all that the latter had to say, and he chuckled grimly when Seymour's plot was laid before him.

"Upon my word, sir, you ought to have been in the force yourself," he exclaimed. "I never heard a neater scheme. I have been puzzling my brains the last day or two for some way of getting hold of Anstruther. I can nobble Carrington at any moment; in fact, I have a warrant for his arrest in my pocket now. You see, I can easily prove that he has been disposing of his clients' securities, but that hardly affects Anstruther. I suppose you want me to go round to the Great Metropolitan Hotel, and compel 'Simple Charlie' to act as bonnet for us. I have not the slightest doubt that he will be able to find a good substitute if he likes. But there is one little difficulty in the way which you have not thought of."

"Oh, yes, I have," Seymour replied. "I know perfectly well what you mean. You mean that even a burglar has some code of honor, and that he would hesitate to betray a pal into such a trap as this. But if the substitute that I have in my mind is acceptable to you, there is no reason for further anxiety."

Seymour scribbled a name on a sheet of paper, and handed it across to Bates. The latter laughed as he read it.

"Oh, most assuredly you ought to have been in the force," he said. "The thing is so clever, and yet so delightfully simple."
