"Telegraph to him to meet you at Charing Cross Station. I can depend upon my man Smith to use his nerve and discretion. Moreover, he knows Inspector Winter, of Scotland Yard, and should trouble arise, which I do not anticipate, this acquaintance may be useful to you. The third person who will meet you will be the ex-sergeant of police, whose report to me you heard yesterday. He will point out to you the flat tenanted by the invalid lady. You speak French well, and after a few questions you should be able to satisfy yourself whether or not the person who opens the door to you when you visit that flat is acting a genuine part. You can pretend what you like, but if admission is denied to you I want you to force your way inside and see that invalid lady at all costs. In the event of a gross mistake having been committed you must apologize most abjectly and assuage the wounded feelings of the servants with a liberal donation, whilst the ex-sergeant of police will advise you as to any other place which may demand personal inspection. I do not conceal from you the difficulties of your task, or the chance that you may get into trouble with the police. But the fact remains that Talbot, alive or dead, is concealed somewhere in the neighbourhood of the Carlton Hotel, and it is high time that this portion of the mystery attending his disappearance should be made clear. Do you follow me?"

"Precisely," said Fairholme. "My programme appears to be very simple. I am to kick down any door that is pointed out by the ex-policeman, provided I am refused admission by fair means."

Brett laughed. "I think," he cried, "you have put my instructions in very direct and succinct form. All I hope is that the invalid lady may prove to be an elderly fraud. It only remains for me to give you my blessing and say good-bye."

"But what about you?" said the earl anxiously. "Suppose we come across Talbot to-night, as you anticipate, where shall I find you to-morrow?"

"You must telegraph to me here," was the answer, "and you must possess your soul in patience until you hear from me.

"No, don't protest," he went on, as Fairholme gave indications of impatience. "You need not fear that you will be left out of the denouement, whatever it be. I am sure to need your help before long, and I will cable you at the first possible moment. For that reason, should you leave your house for more than hour or so, I hope you will make special arrangements for telegrams to reach you without delay."

"You may rely on that," was the hearty answer. "But look here, Brett. It is 10.45 a.m. now. If I have to catch that 11.50 train from the Gare du Nord I have no time to lose. By the way," he added, turning at the door, "is there any reason why I should not wire to Edith to expect me to-night?"

"Not the slightest," said Brett, smiling, "except perhaps this, that instead of calling on Miss Talbot this evening you may be locked up on the charge of housebreaking."

"Um," said the earl, thoughtfully, "I had not thought of that. It will be more fun to take her by surprise. So here goes to get my traps packed."

After Lord Fairholme's departure, Brett took matters easily. He did not put in an appearance at the Prefecture until late in the afternoon, and, as he surmised, the commissary whom he encountered the previous night had even then only just arrived at his office. Without any difficulty, the barrister was introduced to the official, who evidently awaited an explanation of the visit with great curiosity.
