The detective waited curiously, but Crawford did not complete the sentence, and a little silence fell between the two.

As Stone had tossed off his drink, he passed them once more. When he reached the door, however, he halted for a moment, then, swinging around on his heel, beckoned to Crawford. It was almost a gasp of relief that broke from the latter’s lips as he rose.

“Hello!” he murmured. “He wants to speak to me, does he? Excuse me, Mr. Carter.”

The eager way in which he hurried toward his partner revealed to the detective how anxious he was to make friends again.

The two figures passed out through the doorway, and Nick mechanically picked up a magazine from a neighboring table. Half an hour passed; then, leaving the smoking room, the detective went off in search of Chick. His young assistant was not to be seen, and presently Carter returned to the boat deck, found a quiet gap between two suspended boats, and, leaning on the rail, watched the distant lights along the coast.

Perhaps fifteen minutes later the detective heard a quick, muffled cry, followed by the creak of a boat as some heavy object swung against it. He straightened up and listened. A moment later a half-choked voice came to him:

“Jim! Jim! Good heavens! Are you trying to murder me?”

Nick recognized the voice as that of Crawford’s, and, with a swift bound, he leaped out of the dark gap between the boats in which he had stood concealed.

Sprinting forward along the deserted deck, he followed the direction of the sound, and in another gap he saw standing out against the background of the sea two struggling figures. They were locked in each other’s arms, and one of them was swaying out over the rail at a perilous angle. The detective saw that the figure of the man bending over the rail was that of Crawford, and above him, with his fingers clutched tightly around his throat, was James Stone. The former was clutching at the murderous wrists of his companion, trying to release the fierce grip, but even as Nick sighted them Stone made another vicious lunge, and Crawford’s body was all but thrust out over the rail into the sea.
