Rows of the lights began to twinkle, one behind the other, at the head of the bay, and music drifted across the water. A bright glow marked the plaza, where a band was playing, but the harbor was dark except for the glimmer of anchor-lights on the oily swell. The occasional rattle of a winch, jarring harshly on the music, told that the Danish boat was working cargo. A faint, warm breeze blew off the land, and there was a flicker of green and blue phosphorescence as the sea washed about the end of the mole. "I wonder how you'll feel if Kenwardine doesn't come," Jake said presently, looking at Dick, who did not answer. "He will come," Don Sebastian rejoined with quiet confidence. "Well, I guess he must know he's doing a dangerous thing." "Senor Kenwardine does know, but he plays for high stakes and takes the risks of the game. If it had not been necessary, he would not have ventured on British soil, but since he was forced to go, he thought the boldest plan the safest. This is what one would expect, because the man is brave. He could not tell how far my suspicions went and how much Senor Brandon knew, but saw that he was watched and if he tried to hide his movements he would betray himself. It was wiser to act as if he had nothing to fear." "As he was forced to go, his business must be important," Dick said thoughtfully. "This means he must be dealt with before he lands at Kingston. If we allowed him to meet his confederates there, the mischief would be done, and it might be too late afterwards to stop them carrying out their plans." Don Sebastian gave him a quiet smile. "One might learn who his confederates are if he met them. It looks as if you would sooner deal with our friend on board." "I would," Dick said steadily. "His plotting must be stopped, but I'm inclined to think I'd be content with that." "And you?" the Spaniard asked, turning to Jake. "I don't know that Kenwardine is in the worst of the plot. He was a friend of mine and it's your business to prove him guilty. I mean to reserve my opinion until you make your charges good." "Very well," said Don Sebastian. "We'll be guided by what happens when we see him." They let the matter drop, and half an hour later a white light and a green light crept out of the dark to seawards, and a faint throbbing grew into the measured beat of a steamer's screw. Then a low, shadowy hull, outlined by a glimmer of phosphorescence, came on towards the harbor mouth, and a rocket swept up in a fiery curve and burst, dropping colored lights. A harsh rattle of running chain broke out, the screw splashed noisily for a few moments and stopped, and a launch came swiftly down the harbor. "The port doctor!" said Dick. "There's some cargo ready, and she won't sail for three or four hours. We had better wait until near the last moment before we go on board. If our man saw us, he'd take alarm and land."
