“Neatly done, Halstead,” greeted the voice of Mr. Delavan, as that gentleman, holding a napkin, appeared at the cabin door below for an instant. “I heard it all.”

“If that fellow hadn’t had his canvas rigged we might have had to stand by him,” replied Halstead.

A few minutes later it was seen that the racing craft was coming in slowly, under that small sail. It looked probable, then, that the break in her engine had been genuine.

Going at full speed, the “Rocket” was not long in making Shinnecock Bay. Soon afterward the young captain ran his craft in at a pier, on which stood a waiting automobile.

“I’ll be back for the rest of my lunch soon, steward,” announced the owner, stepping ashore. He entered the automobile, and was whirled away through the streets of East Hampton. Mr. Moddridge remained in the cabin, though he played nervously with knife and fork, eating little.

In fifteen minutes Francis Delavan returned, walking lazily from the touring car to the deck of his boat, his face expressive, now, of indolent content.

“Take us out a little way, captain,” requested the owner. “We want some good, cool sea air in which to finish the meal, eh, Moddridge?”

“I—I’m too excited to eat,” protested the smaller man. “Tell me, is everything all right at the New York end?”

“Oh, yes, I fancy so,” drawled the owner. “Steward, some more of that excellent salad, if you please.”

As Captain Tom slipped his craft out of Shinnecock Bay once more they made out the mysterious speed boat, still under sail and at a distance, making slowly for the Long Island coast.
