"Simply because it denotes a secure sense of complete ownership. Miss Talbot would never hold such a view of your intellectual powers if you were merely a friend."

"Well," said the earl dubiously, "that is a new point of view for me at any rate."

"It is a fact nevertheless. But we have not much time, so we must reserve any further consideration of feminine inconsistency. The fate of the Frenchman must be determined to-day, and to decide the question I must act through the police, so a conversation with our friend the commissary becomes inevitable. And now to return to the hypothetical part of my conclusions. I began by assuming that the individual who planned the Albert Gate outrage and subsequently sought to bamboozle his employers by palming off on them a set of spurious diamonds, is far too acute to attempt to dispose of the real gems for many months yet to come. He obtained sufficient funds from the Turks, in pursuance of what may be termed the legitimate part of his contract, to enable him to live for a considerable period without further excitement. Closely associated with him in the present adventure is La Belle Chasseuse. Neither would endeavour to procure safety by flight to a foreign country. They will seek insignificance by living in a normal and commonplace manner. What more easy, for instance, for Mademoiselle than to return to the life of the circus, whilst her lover—granted that he wished to remain in her company—will obtain some suitable employment in the same circle. There is a suspicion of a joke in the statement, but I am quite serious. The mere consciousness that they have in their possession a vast fortune, which time alone will enable them to realize, will serve as an inducement to undergo the period of hard work which means safety. You remember that the lady's father, Gros Jean, visited the Gare de Lyon yesterday?"

Fairholme nodded.

"I think you will find that he was depositing there the necessary luggage for a contemplated trip into the interior, so that Mademoiselle might slip out late at night quietly and unnoticed and join her lover at some preconcerted rendezvous, a thing which we now know she did. I cannot, of course, be certain whether the Frenchman who signalled to her in the Café Noir was himself the favoured individual. It is possible. By the way, what height is Talbot?"

"About five feet nine."

Brett pondered for a little while.

"Yes," he communed aloud, "I think I am right. That pink-and-white Frenchman is the master mind in this conspiracy. And to think that the unintelligent muscles of a couple of thick-headed French policemen should have crudely interfered with me at such a moment!" He sighed deeply.

"Never mind," he went on, "it cannot be helped. I must keep to the thread of my story. Mademoiselle Beaucaire left the Cabaret shortly after eleven o'clock. We cannot be certain that she went to the Gare de Lyon, but the cab unquestionably set off in that direction. It is a long drive from Montmartre to the Lyons station. We will give her, say, until twelve o'clock to reach there. Now, unless she was journeying to some suburban district—a contingency which upsets the whole of my theory—there was no main line train leaving for the south until 1.5 a.m., and that is a slow train, stopping at nearly every station south of Melun. Let us suppose that they guard against every contingency. She and her companion wish to escape the scrutiny of detectives. It will at once occur to you that they run far more risk of observation if travelling by a fast express than if they elect to journey by the commonplace trains which only serve the needs of country districts."

"It did not occur to me," said Fairholme candidly. "Still, there is a lot in the idea all the same."
