"Yes, I did that, and now I am sorry for it, for I have thought of a much better scheme for getting even, and having my revenge on you."

"But why do you want to be revenged on us?"

"Because of what you have done!" and the man's voice took on an ugly tone.

"But what did we do?" begged Mark.

"You'll know soon enough," was the answer, with a cunning laugh, and then Mark was sure he had to deal with a lunatic. He ceased his struggles to loosen the bonds, and resolved to meet cunning with cunning. He would bide his time.

"Will you promise to be quiet, and not kick up a fuss if I get you something to eat?" asked the man.

"Yes; but I'd rather have a drink of water first. I feel sick."

"Very well, you shall have some water. I'll have to go out and get it, but I must first blindfold you, so that you will not discover the secret of this room."

Mark could not help himself, for he was bound, and when the man had tied a handkerchief over his eyes, Mark heard his captor moving about.

Next there came a sound as of some heavy body, or object, being pushed across the room. Mark felt a draught of wind on his face, but it ceased instantly, and he knew that he was alone. He tried to work the bandage from over his eyes, and he endeavored to loosen his bonds, for he did not consider that this violated his promise. But it was of no effect.
