"I think," said Gaultier, speaking slowly and thoughtfully, "that your view is the right one, Mr. Brett. There is much more in this business than meets the eye, and any man who believes that Jack Talbot would mix himself up in it must be a most determined ass. Of course, such people do exist, but they shouldn't be in the police force. You are going on to Paris, you said?"

"Yes."

"Then we can travel together. All that you have said is quite new to me. Curiously enough, I have just returned from Constantinople, and I may be able to assist you."

Brett silently thanked his stars for the gratuitous circumstance which threw him into the company of Captain Gaultier. He recognized that the King's messenger, with the precaution that might be expected from one whose daily life demanded extreme prudence, desired to mentally review the strange facts made known to him before he committed himself further. With ready tact the barrister changed the conversation to matters of the moment until they reached the pier at Calais, when both men, not encumbered with much luggage, were among the first flight of passengers to reach the station buffet.

On their way they captured a railway official and told him to reserve a coupé lit compartment. In the midst of their hasty meal the Frenchman arrived, voluble, apologetic. The train was crowded. Never had there been such a rush to the South. By the exercise of most profound care he had secured them two seats in a compartment, but the third had already taken itself. He was sorry for it; he had done his best.

When they entered their carriage the third occupant was in possession. He was French, aggressively so. Phil May might have used him for a model. The poor man had been wretchedly ill from the moment he left Dover until the vessel was tied to her berth in the harbour at Calais. He paid not the least attention to the newcomers, being apparently absorbed in contemplation of his own misery. The two Englishmen, though experienced travellers, were sufficiently insular to resent the presence of the stranger, whom Brett resolved to put to the language test forthwith.

"It is very cold in here," he said. "Shall I turn on the hot air?"

The Frenchman seemed to understand that he was addressed. He looked up with a shivering smile and explained that he had only booked one seat. The remainder of the compartment was at their disposal. He was evidently guiltless of acquaintance with the English tongue, but Brett did not like his appearance.

Though well-dressed and well-spoken he was a nondescript individual, and the flash of his dark eyes was not reassuring. Yet the man was so ill that Brett forthwith dismissed him from his thoughts, though he took care to occupy the centre seat himself, thus placing Captain Gaultier on the other side of the carriage. After a visit from the ticket examiner, the Frenchman disposed himself for a nap and the train started.
