“When the time comes,” the doctor continued, “I may ask you to assist me in calling my enemies together. Oh, I’ll show you some sport! You love sport, and you’ll laugh at this, I promise you. We will get them to stand in one long row, and then I’ll bring the bricks and mortar and stone and iron thundering down upon them. It will be just like children playing with blocks.”
The doctor laughed silently to himself as he thought of this, and Bart felt a cold shiver creeping over him.
“I must tell Elsie everything,” he thought. “She must not remain in the house with this madman.”
Then he saw her coming toward them.
“Excuse me, doctor,” he said. “I wish to have a chat with Miss Bellwood.”
“But not a word of the great secret to her!” warned the man, in a whisper. “If you value your life, be silent!”
