"Now that things are quiet again," he said, "I think we might talk a little. I promised our two American guests that they would find out the secret of this little beast, and now is as good a time as any."

"I can get a saw to open it with," Rick offered eagerly.

Ben grinned. "Patience, Rick. First we must paint a background, so that we may see the whole picture. Where shall we begin? With Moustafa?"

Kemel Moustafa maintained a sullen silence.

"No co-operation? Then I shall begin. Boys, I regret to inform you that Mr. Kemel Moustafa is a member of a conspiracy to overthrow the United Arab Republic government."

Rick and Scotty turned to look at the mustached man. He sat impassively.

"His brothers also are in this conspiracy. He told you they were in Beirut, but he was not truthful. They are in jail, here in Cairo, awaiting trial. We picked up Ali the day before you arrived. We did not get Fuad until an hour before you visited him. The local people were nervous over the arrest. Many in that neighborhood support the Moustafas."

Kemel Moustafa spoke. "I'm not in it. You can't prove that I am."

Ben nodded. "Proof may be difficult. That is why you were allowed to remain at large while we collected your brothers. But, meanwhile, we have you on a charge of armed robbery, since you used a pistol to get the cat from our American friends a few minutes ago." He turned to the boys. "Talk of overthrowing a government probably sounds strange to you. It has been many years since the American government was in any danger of revolt."

"We don't understand some of the foreign revolutions," Rick agreed. "But I suppose when a group isn't satisfied, it's apt to plot a revolution if there seems to be a chance of success."
