ca and England. I'll pay
you back some day, too."

"Yeah!" Dawson sneered. "When I'm a hundred and six and have lost all my
teeth. When I can eat only soup instead of a thick steak like I just
bought for you. But you just wait, my little bowlegged pet! I'll--Oh-oh!
The man in gray, eh?" Dawson added the last because of the flinty look
that had suddenly leaped into Farmer's eyes.

"Quite!" Freddy murmured. "And I'm jolly well sick of this hide-and-seek
business. I'm going to find out what the blighter's up to. I detest
shadows, excepting my own."

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--"

The F.B.I. agent grinned and shrugged.

"But now that the cat's out of the bag," he said, "supp
