r. Cooler, somewhat mockingly. "You are very much
excited, young man. I do not know what you are driving at."

"Don't lie! I tell you it is dangerous! We are desperate!"

"You really seem so."

"Where is he?"

"How do I know?"

"You do know! He followed you, and you trapped him some way. What have
you done with him?"

"He! he!" chuckled the little man. "Followed me, did he? Why did he do
that? It seems to me he should have been more careful."

"There it is!" burst from Hodge. "That is the same as a boast! Now we
know you have done something to him!"

"You are a very knowing young man."

Now the manner of the man in gray aroused the anger and resentment of
the boys. He seemed to be taunting them.

"Shall we shoot the snake, Bruce?" asked Diamond, his face purple with
passion. "Shall we avenge Frank?"

"Not just yet," said Browning. "We will give him a chance for his life."

"You are very kind!" murmured Mr. Cooler.

"If he will tell us what has become of Frank--if he will lead us to
Frank, we will spare his life."

"What if I don't know where he is?"

"You do know. You dare not deny it!"

"You are very much mistaken, for I do deny it. I give you my word of

"Ha!" exclaimed Hodge. "Then you know what became of him?"

"No. He followed me over to the other side of the island, and then he
started to return by coming straight back through the woods. That is all
I know. I am here to learn if he returned safely. If he did, I intended
to warn him that his life was in danger if he should go about the island
alone. You must see that I am serious now."

"Oh, yes, we see!" came scornfully from Diamond. "It is too thin! It
will not work, Mr. Cooler. You know too much not to know more. If you
wish to keep your skin whole, just lead us straight to Frank
Merriwell--that's all!"

"I can't. I would do it if I could. But I give you my word to do my best
to save him if he is in trouble. That is the best I can do."

Diamond's anger caused him to lose his head so that he threatened the
old man with his fist. He quickly realized what he was doing, however,
and, with an air of apology, he cried:

"If you keep it up, you will lead me to do something of which I shall be
ashamed. Yo
