"I thought the same thing."
"What that reason can be I do not know."
"But, Frank," said Bruce, hesitatingly, "you heard something as we stood beside that grave up there in the woods?"
"Yes."
"A whisper?"
"Sure."
"What did it say?"
""Dead and buried.""
"Then it was not imagination, for we both heard the same thing. Now how do you explain that?"
"Somebody whispered the words."
"Where was that somebody?"
"You know just as well as I do; but those words were whispered for our ears to hear. We heard them."
"I do not believe in ghosts any more than you do, Merriwell, but I will admit that there was a mighty queer feeling came over me as we stood there near that grave."
"I felt it," confessed Frank. "Had I believed in ghosts, I should have been badly frightened."
"Well, let"s look this building over. We may find something in here."
So they began to explore the old boarding house. It was a large building, and they climbed the stairs to the second story, where none of the windows were boarded up. Up there were the rooms where the laborers had slept. They looked through them all, but found nothing of interest.
At last they stopped by a window and looked out upon the water.
"By Jove!" exclaimed Merriwell. "Look down there!"
"What is it?"
"A boat."
"Where?"
"Beyond the land at the other side of the cove. It"s laying close in to sh.o.r.e. See the mast?"
"Yes, I see it now. Why, it almost seems aground! Wonder what it"s there for?"
"Whoever was in the boat has come ash.o.r.e on the island."
"Then why didn"t he run into the cove down here?"
"Because the boat would be seen in the cove, and where it lays it is not liable to be seen from the island."
"Why should anybody wish to come onto the island here and not be seen?"
"I don"t know, but I"ll wager something that that is the lap-streak sailboat belonging to our friend, the c.o.c.k-eyed man. If I am right, he is somewhere on this island."
"He warned us not to come here."
"Yes. He told us what happened to the Boston man who came here. It was plain to me that he wanted us to keep away. He ran down ahead of us, and he is on the island. Why should he care to frighten us away? Why should he hurry to get here ahead of us? I tell you, old man, this is a mystery worth solving."
Bruce grunted. He felt that Merriwell was right, but he realized it might not be an easy thing to solve the mystery of the island.
The big Yale man stood looking out of the window and watching the boat, while Frank continued his investigations. Merriwell wandered from room to room, and at last descended the stairs again.
"If he gets an idea that there is really a wonderful mystery here,"
muttered Bruce, "he will stay till he has solved it if he spends the remainder of the summer in this vicinity. Never saw a fellow who took such an interest in anything mysterious."
The wind was rising again. It rattled a window, and somewhere about the building it made a loose board clap, clap, clap, in a way that made Browning think of clods falling on a coffin.
All at once, somewhere down below in the old building, a shriek rang out, startling, shrill, wild and awful. It froze the blood in Browning"s veins and seemed to cause his hair to stand upon his head. Following the shriek came--silence!
CHAPTER XX.
FRANK SEES THE MONSTER.
Instantly Browning thought how the fisherman had told of the awful screams that came from the lips of the monster of the island. Had that monster uttered this cry?
Where was Merriwell?
"Frank!"
Browning shouted the name of his friend and the empty rooms echoed with the sound.
"Frank Merriwell!"
From room to room rushed the big fellow. There was no answer to his cries.
Quickly satisfying himself that Merriwell was nowhere in the upper story of the boarding house, Bruce bounded down the stairs four at a time.
"Frank, where are you?"
No sound save his own voice and the echoes.
A sickening sensation seized upon Browning. He began to feel that a calamity, a tragedy, had taken place.
From room to room he rushed, but he saw nothing of the one he sought.
