"We could, if we knew where to find him. But Youssef is a hard man to locate when he goes underground. We've been trying to get something on him for years, and we know him well. This time he's over-played his hand and we've got him. It's only a question of time."

"How about Moustafa?" Rick asked. "Is he guilty of anything?"

The police officer finished his coffee and rose. "Not yet," he said. "But he will be. Now, stay together at all times. Ride with the taxi driver who will be waiting for you in the hall. Otherwise, go about your business as usual, and have a good time."

Scotty saw him to the door, then turned to Rick. "Moustafa isn't guilty of anything yet, but he will be. That's interesting."

Rick thought so, too. "Isn't it pretty careless, leaving the cat at the project?"

"Seems so," Scotty agreed. "But I think Ben knows what he's doing."

"I guess you're right," Rick said soberly.

After more coffee and a shower, he felt like himself again. There was work to do at the project, so the two boys picked up the police driver, who was keeping an eye on their door, and rode to the project.

The scientists greeted Rick happily. "We were pretty worried for a while," Winston said, and the Egyptians echoed him.

"We don't usually treat tourists this way," Farid said jokingly, but behind the smile Rick sensed that the Egyptian scientist was embarrassed by what had happened to a guest.
