He was looking out to windward as he spoke. He took the rudder out of Mr. Carter's hands presently, and that gentleman rolled himself in his new railway rug, and lay down in the bottom of the boat, with one of the men's overcoats for a blanket and the other for a pillow, and, hushed by the monotonous plashing of the water against the keel of the boat, fell into a pleasant slumber, whose blissfulness was only marred by the gridiron-like sensation of the hard boards upon which he was lying.

He awoke from this slumber to hear that the wind had changed, and that the Pretty Polly—the boat belonging to the two fishermen was called the Pretty Polly—was gaining on the Crow.

"We shall be alongside of her in an hour," one of the men said.

Mr. Carter shook off the drowsy influence of his long sleep, and scrambled to his feet. It was bright moonlight, and the little boat left a trail of tremulous silver in her wake as she cut through the water. Far away upon the horizon there was a faint speck of shimmering white, to which one of the young men pointed with his brawny finger It was the dirty mainsail of the Crow bleached into silver whiteness under the light of the moon.

"There's scarcely enough wind to puff out a farthing candle," one of the young men said. "I think we're safe to catch her."

Mr. Carter took a cupful of rum at the instigation of one of his companions, and prepared himself for the business that lay before him.

Of all the hazardous ventures in which the detective had been engaged, this was certainly not the least hazardous. He was about to venture on board a strange vessel, with a captain who bore no good name, and with men who most likely closely resembled their master; he was about to trust himself among such fellows as these, in the hope of capturing a criminal whose chances, if once caught, were so desperate that he would not be likely to hesitate at any measures by which he might avoid a capture. But the detective was not unused to encounters where the odds were against him, and he contemplated the chances of being hurled overboard in a hand-to-hand struggle with Joseph Wilmot as calmly as if death by drowning were the legitimate end of a man's existence.

Once, while standing in the prow of the boat, with his face turned steadily towards that speck in the horizon, Mr. Carter thrust his hand into the breast-pocket of his coat, where there lurked the newest and neatest thing in revolvers; but beyond this action, which was almost involuntary, he made no sign that he was thinking of the danger before him.

The moon grew brighter and brighter in a cloudless sky, as the fishing-smack shot through the water, while the steady dip of the oars seemed to keep time to a wordless tune. In that bright moonlight the sails of the Crow grew whiter and larger with every dip of the oars that were carrying the Pretty Polly so lightly over the blue water.

As the boat gained upon the vessel she was following, Mr. Carter told the two young men his errand, and his authority to capture the runaway.
