"Diamonds. Rubies. Maybe a radium needle in a lead shield. The possibilities are endless."

"Uhuh. Only one thing bothers me a little. Why use a plastic cat as a container to smuggle things into Egypt? There must be better ways."

"This way hasn't been very successful," Rick agreed. "Anyway, here's the hotel. Let's ask Kemel Moustafa."

Over coffee, Rick asked the third Moustafa brother many questions, and received answers to most of them--although the answers were not always satisfactory.

Moustafa antic.i.p.ated some of the questions. As the waiter brought coffee, he pulled out his wallet and showed the boys his ident.i.ty card, driver's license, and business card. Clearly, he was Kemel Moustafa.

"I have been to Khartoum on business," he said. "Last night I returned to the city and found that a family emergency had taken both of my brothers out of town. Fuad left very suddenly, after he had written to you. I apologize on his behalf. However, he must be excused, since a call from Ali, in Beirut, sent him running to the airport to catch the next flight. He simply had no time even to call you. His secretary tried to call you today, without success."

"We wondered," Rick said.

"Of course. And you are also wondering how I came into the pyramid at just the right time. A fortunate accident. You see, I came to Sahara Wells hoping to see you, but you were sightseeing. Dr. Winston was kind enough to tell me where you were. I simply went hunting for you. A quick drive around the area told me you must be in one of the pyramids, and the biggest one seemed the most logical place to look for you."

Rick believed him. Moustafa wouldn't tell a tale that a moment's talk with Winston would disprove.

"Who was the man who pretended to be your brother Ali?" Scotty asked.

"His chief clerk. He is an arrogant type who often shows poor judgment.

Instead of simply explaining to you that Ali was out of town, he apparently told you he was Ali. This was the case?"

Rick confirmed it.

"He will be discharged at once. I suspected it when I questioned him last night. He gave some lame excuse about your refusing to hand over the cat to anyone except my brother Ali. He told Fuad the same thing, according to his secretary."

"It wasn't such a lame excuse, Mr. Moustafa," Rick corrected. "Mr.

Bartouki asked us to deliver the cat to Ali Moustafa. We have no instructions to deliver it to anyone else."

"I see. And I commend your discretion. But my brother Ali will not return for many weeks, and you will not want to take the cat back to America with you. So we will telephone Mohammed Bartouki, and you will hear directly from him that I am a suitable subst.i.tute for my brother."

Scotty asked bluntly, "Why is the cat so important?"

Moustafa spread his hands wide. "Why not? The creature will open a new industry in Cairo. It will employ a number of people. It will make a profit for the Moustafa-Bartouki enterprises. It will please the tourists. Obviously the cat is important."

Rick tossed in his loaded question. "How did you know the cat in the pyramid wasn't the cat we brought from America?"

Kernel Moustafa's thick eyebrows went up. "It was obvious, was it not?

The broken cat was made of colored concrete. The cat Bartouki took such pains to develop was of a plastic that does not have the graininess of concrete. If you tell me the one in the pyramid was indeed the original, I will be very disappointed. Such a model would not be suitable."

"It wasn't," Rick said briefly.

"Ah. And where is the original?"

Rick's smile was every bit as warm and friendly as Kemel Moustafa's.

"Perhaps the answer to that had better wait until we have talked to Bartouki."

The Egyptian's smile broadened. "Discretion in one so young," he proclaimed, "is a rare and precious thing." He put money on the table for their coffee and rose.

"You will excuse me? I have business in the city. But tonight at seven I will come to your hotel and we will phone our friend in New York. It will then be noon in New York, and we will find him reading the Koran at home. This is his custom. Until then, _a.s.salamo alaik.u.m_, which is to say, 'Good day to you.'"

As the boys walked to where Ha.s.san waited, Scotty grinned at Rick.

"'Discretion in one so young,'" he quoted, "'is a rare and precious thing.' He should know you as I do. Discretion has nothing to do with it. You just don't want to part with that cat until you know everything there is to know about it."

Rick shrugged. "I haven't heard you volunteering to hand the poor creature over. Besides, our pal Kemel is not all that he seems."

"And how do you know?"

"Easy. Did he ask us who jumped us in the pyramid, or why? Did he explain why he carries a Luger? Nope, to both. He carries a Luger because there's danger in this business. And he knows why those Arabs jumped us. He may not know them by name, but he knows what they were after, and he knows why."

"Which is more than we know," Scotty concluded.

"For now," Rick agreed. "But we'll find out before we're through, one way or another!"

CHAPTER XII

Third Brother Stops Smiling

Rick opened the door to a knock at precisely two minutes of seven, and admitted Kernel Moustafa. The Egyptian shook hands politely. "It takes some time to get a call through," he said, "so I placed our call an hour ago. The operator a.s.sured me it would go through precisely at seven."

Moustafa turned to Scotty and shook hands again. "According to my watch, we have only a few seconds to wait. Mr. Brant, you will answer the phone, if you please. Identify Bartouki to your own satisfaction, then ask him about Kemel Moustafa. Then turn the phone over to me, and I will talk with him. After that you take the phone back again, and he will give you final instructions. This is acceptable?"

"Absolutely," Rick said. He thought quickly. How could he establish Bartouki's ident.i.ty for certain? Then, as the phone rang, he knew.

Rick answered. "Rick Brant speaking."

"On your call to New York. Mr. Bartouki is on the line. Go ahead, please."

Rick raised his voice instinctively. After all, New York was a long distance away! Then he realized that electronic facilities reduce the need for shouting, and lowered it again. "Mr. Bartouki? This is Rick Brant."

"Good morning, Rick. Ah, but this is evening in Cairo, is it not?"

Rick was sure he identified the little merchant's voice, but he went ahead anyway. "Mr. Bartouki, please forgive me, but I must establish your ident.i.ty beyond any doubt. Can you tell me what color dress my sister Barbara wore at your reception, and the color of her hair and eyes?"

"Of course. Her dress was a very attractive blue wool with a red leather belt. She is very blond, with dark-blue eyes, and she is about my height."

Rick was satisfied. "Thank you, sir. The reason I had to be careful is this. We went to Ali Moustafa's shop, and a man who did not answer your description of Ali Moustafa pretended to be him. We refused to give up the cat. Then our room was searched. We received a letter from Fuad Moustafa, and when we went to his house it was padlocked. Last night a man came to our room with a pistol and demanded the cat. We gave him a copy we had made in concrete. I should add we also were attacked in front of the Egyptian Museum by men who searched us. That was why we made the copies in concrete. The real one is hidden. Then, this morning, we were attacked again, inside the pyramid. We were rescued by Kemel Moustafa. He is here with us now. If you approve, we will give him the cat. If not, tell us what to do with it."

Bartouki's voice sounded incredulous over the ocean miles. "This is incredible! I must know the meaning of this. May I speak to Kemel?"

Rick handed the phone to the third brother and listened. Kemel launched immediately into a rapid flow of Arabic.

Scotty interrupted, "Can you speak in English please?"
