Bates had laid his plans very carefully and very well indeed. In many respects Rigby had got the best of the detective, but this was as much due to circumstances as anything else. Still, when it came to the technical side of the case, Rigby was no match for the inspector. It was nearly nine o'clock before Bates called at Carrington's rooms and asked to see the latter. There was no occasion yet for Bates to assume the very effective disguise with which he was to trick Anstruther. There would be plenty of time for that. Carrington was just finishing his dinner--so his man said. He was not very well, and did not care to see anybody. But Bates put the man aside in his own easy way, and walked into the dining-room without the trouble of announcing himself.

That Carrington was suffering from some mental and physical excitement was perfectly plain. His face was ghastly pale, his eyes were bloodshot, and there was a twitching of his lips which told a plain tale to an experienced officer like Bates. Carrington scowled, and demanded the meaning of this unwarrantable intrusion.

"I don't think you will find it unwarrantable when you have heard me to the finish," Bates said. "Nor will it pay you to take this tone with me. I am an inspector from Scotland Yard, and unless you answer my questions freely, I shall have to put them in a more disagreeable form."

Carrington changed his note altogether. His face became still more pallid. He motioned Bates to a chair. He would have found it hard to have spoken just then. Bates waited a moment to give the other time to recover. Carrington at length found words to ask Bates what his business was with him.

"It is with regard to your affair at the bank," the inspector explained. "You may not be aware of the fact, but the case has been placed in my hands by my superiors."

"Oh, you are alluding to the burglary," Carrington said.

"We will call it a burglary for the present," Bates replied, with a significance that there was no mistaking. "I have gone into the matter carefully, and I have come to the conclusion that there was no burglary at all."

Carrington jumped to his feet with a well-simulated air of indignation. He advanced towards Bates threateningly.

"You insolent scoundrel!" he cried. "What do you mean? Do you know you are dealing with a gentleman and man of honor?"

"Softly, softly," Bates replied. "I think we had better understand one another. I have in my possession at the present moment a warrant for your arrest for fraud and embezzlement, relating to certain jewels and other valuables deposited in your keeping by various clients. It is in my power to execute that warrant at once. The case is much too serious a one for bail, and it is for you to say whether you will remain for the present in your comfortable quarters, or pass, at any rate, the next two months in jail."
