"It is square," said John, slowly, and he drew a little closer to where the pretended astrologer sat on a divan in the midst of hangings, which let but little light into the room.
"Yes, square."
"And flat."
"Yes. Now one more little detail. I begin to see a glimmering of it before me," and Professor Ali Baba pretended to go into a trance.
"It is white with black markings on it," John went on. "In fact it is something you have right here in this house."
"What's that?" fairly shouted the professor.
"It's that card you stole from Jack Ranger!" went on John, coming close to the fakir and gripping him by the wrists. "The card you took from his pocketbook the night you broke into our rooms. I want it back! Give it up, you scoundrel, or I'll call in the police."
"Let go!" yelled the professor.
"Give me the card!" shouted the Indian, struggling to hold the man, who was trying to break away.
"Help!" cried the professor.
