With a grim nod Freddy Farmer stepped past Dawson and walked over toward the man in gray who was just leaving the dining room. Dawson impulsively swung around and followed him. The man in gray acted as though he did not see Freddy, but the English youth stopped in front of him, barring his way.

"Have you been wishing to speak to me, sir?" Freddy asked quietly. "Is that why you've been following me all over town all day?"

The man in gray looked blank for a moment. Then he shrugged and gave Freddy a friendly smile.

"It has been rather obvious, hasn't it, Captain Farmer?" he said as both Freddy and Dawson stared at him, dumbfounded. "But you went to a lot of places where I couldn't help but show myself. I guess you've had enough experience to guess when you're being trailed. The name is Carter, Captain."

As the man in gray introduced himself, he slipped something out of his pocket and held it cupped in his hand so both youths could see it. They took a good look at the gold F.B.I. badge and quickly raised their eyes to the man's face.

"The F.B.I. no less!" Dawson breathed. "What's up? Is Farmer wanted by the F.B.I.—I hope?"

The man chuckled and shook his head.

"No," he said. "Neither of you are, in fact. The two of us just had orders to keep an eye on you both."

"'Two of us'?" Dave echoed sharply. "You mean—" He let the rest go as the F.B.I. agent nodded.

"That's right, Captain Dawson," he said quietly, and made a faint gesture toward the other side of the lobby. "My partner has been looking after you, while I tried to keep up with Captain Farmer here. If Captain Farmer hadn't returned to the dining room, I'd have taken on the job of sticking with you, and my partner would have tackled Captain Farmer. Frankly, I would have enjoyed the change. But now—"
