"Yes, I know. That was by my instruction," saying which Mr. Mitchel smiled, and Mr. Barnes once more discovered that he had been fighting against a man who thought of everything. "You see," continued Mr. Mitchel, "I knew that you saw the name of the jewellers on the bill of sale. What more probable than that you should apply there for information? Now, my one object throughout has been, not to defeat justice, but to have time enough elapse for me to win my wager. Therefore, I immediately sent a cable to these persons, 'Answer nothing signed Barnes till you hear from me.' Rather a long cable despatch, but then I don't mind a few dollars. Of course, my letter to them made them shut their mouths to you. It was very simple. However, I myself have not been able to get satisfactory facts from them, and I think it needs a person actually on the ground to ferret out this thing. I believe you are just the man for the case. This letter will give you their assistance, and here is a check for five hundred dollars for expenses."

Mr. Barnes would have refused, but Mr. Mitchel insisted, that from that time on, Mr. Barnes should consider himself regularly employed on the murder case, "though, of course," said Mr. Mitchel, jocularly, "you are still free to work out the robberies."

The two men shook hands at parting, and one would have said that they were separating after a mutually satisfactory interview.


CHAPTER XVII.

A NEW YEAR'S DINNER PARTY.

The 1st of January arrived, and Mr. Mitchel had heard nothing from Mr. Barnes. Inquiry at his office was met by the simple statement, that "The chief is out of town." When he would be back, or where a communication would reach him, could not be learned. A few days before, however, a formal engraved invitation to the dinner party had been mailed to his home address. Mr. Mitchel was annoyed at not having any notification of whether or not the detective would be present. However, he was compelled to go ahead, and depend upon the slight chance that at the last moment he would appear upon the scene. He hoped that this would occur, as otherwise, his scheme for the evening would be incomplete.

The dinner was to be served at ten o'clock that night at Delmonico's, where a private room had been engaged. It lacked ten minutes of the hour for sitting down, and all the guests had arrived, except Mr. Barnes. These were: Mr. Van Rawlston, Mr. Randolph, Mr. Fisher, Mr. Neuilly, who had decided to spend the winter in New York, Mr. Thauret, and several other gentlemen.

It lacked barely half a minute of ten when Mr. Barnes was announced, and entered in handsome evening dress. Mr. Mitchel's face wore a look of triumph as he saw him, and he hurried forward to receive him. Every one present understood why the detective was invited, for it was by this time well known that a wager was to be decided at twelve o'clock. After the exchange of greetings, Mr. Mitchel gave the waiters the order to open the doors of the dining-room, and in the moment's interval managed to get a word with the detective.
