"Hold on a bit: it is my turn now. Suppose I try to pump you."

A giant wave took hold of the vessel and shook her violently, and Brett, though an average amateur sailor, felt that the saloon was no place for him.

"Between you and the ship, Captain Gaultier," he said, "the success of the operation would be certain. I have secured a quiet corner of the deck. If you wish for further talk we must adjourn there."

The transit was effected without incident, much to Brett's relief. After a minute or two he felt that a cigar was possible. He turned to his companion with a quiet observation—

"The vessel has failed. You can start now."

"Well," said Gaultier, "tell me what is the mystery attaching to Talbot's movements. I only heard the vaguest of rumours in the Department, but something very terrible appears to have happened, and, indeed, I heartily wished I had kept my mouth shut concerning my supposed meeting with him last Tuesday, as the affair was no business of mine. Moreover, you have now somewhat shaken my belief in his identity, although I can hardly tell you why that should be so."

Brett paused to make sure that no one would overhear him, but the fierce wind whistling round the chart house and bridge, the seas that smote the ship's quarter with a thunderous noise, the all-pervading sense of riotous fury in the elements, rendered the precaution almost unnecessary. In any case, there was no one near enough to act the part of eavesdropper, and Brett, exercising the rapid decision which frequently impressed others as a gift of divination, determined that to let such a man as the King's messenger into the secret could not possibly be harmful to the interests of his client, whilst his help might be beneficial.

In the fewest possible words, therefore, he poured the tale into the other's wondering ear. When he had finished, Gaultier remained silent a few minutes.

Already the clear radiance of the magnificent light at Calais was sending intermittent flashes of brightness over the deck, and the long shoulder of Cape Grisnez was thrusting the force of the gale back into mid-Channel.
