Andy.

A moment later the man hailed them.

"I beg your pardon," he began, striding up to the two brothers, and
shifting his gaze rapidly from one to the other. "But have you seen or
heard of a large motor boat going ashore around here? I'm looking for
one. There would be a boy in it perhaps--a lad of about your size.
Perhaps he put in here to get out of the storm. I've inquired all
along the coast, but I can't get any word of him. You haven't happened
to have heard anything, have you?"

Frank and Andy looked at each other quickly. At last they seemed on
the track of the mystery.

"Was he a tall, dark lad, with black hair?" asked Frank.

"Yes--yes, that's the boy I'm looking for!" exclaimed the man quickly.

"And was the motor boat a long one, painted white with a green water
line, and with the engines forward under a hood?" added Andy.

"Yes!" eagerly cried the man, in his excitement taking hold of Andy's
coat. "That's the boat! Where is it? I must have it!"

"She's wrecked," said Frank quickly. "We saw her on the Shark's Teeth,

"We have been trying to pick up the wreck of the boat and learn who the

it.

"Yes, he doesn't remember even his name," explained the elder Racer
lad. "But now we can solve the mystery as you know him. You say his
name is Paul. What is his other name? Who are you? Don't you want to
see him? We can take you to him--to Paul."

The brothers eyed the man eagerly. On his part he seemed to shrink
away.

"I--I made a mistake," he said, biting his nails. "I know no one named
Paul. I--I--it was an error. That is not the boy I want. I must
hurry on. Perhaps I shall get some news at the next settlement. I
am--obliged to you."

His shifty eyes gazed at the brothers by turns. Then the man suddenly
turned away muttering something under his breath.

"But you seemed to know him!" insisted Frank, feeling that the mystery
was deepening.

"No--no! I--I made a mistake. His name is not Paul. I am wrong.
That is--well, never mind, I'm
