Dorothy stood up and squeezing past Bill, opened the cabin door.

“And my reply to you is—rats!” she flung back at him. “Of course I’m going with you. There’ll be no argument, please. Get busy and turn over that flywheel while I go forward and slip our mooring.”

Bill made no answer, but with a resigned shrug, followed her out to the cockpit. They had known each other only a few months, but their acquaintance had been quite long enough to demonstrate that when Miss Dixon spoke in that tone of voice, she meant exactly what she said. Bill knew that nothing short of physical force would turn the girl from her project, so making the best of things as he found them, he started the engine.

Bill was heading the boat across the bay when Dorothy came aft again. She went inside the cabin and presently emerged with a thermos of hot coffee, some sandwiches and hard-boiled eggs.

“We may both get shot or drowned,” she remarked philosophically, “but we needn’t starve in the meantime.”

“Happy thought!” Bill bit into a sandwich with relish, “One drowns much more comfortably after having dined.”

“Hm! It would be a cold wet business, though. Doubly wet tonight.” She looked at the black water pock-marked with raindrops and shook her head. “Hand me another sandwich, please. Then tell me how you came to be mixed up with this diamond smuggling gang, Bill.”

By this time they were well on their way across Great South Bay toward the inlet. From the bows came the steady gurgle and chug of short choppy seas as the stiff old tub bucked them. Holding a straight course, the two by the wheel were able to make out the grey-white gleam of sand on Sexton Island.

“Well, it was like this,” began Bill. “You remember the Winged Cartwheels.[[1]] Well that was a Secret Service job for the government.”

“I know,” nodded Dorothy.
