“We’re only human,” Bert Young protested. “And Varania is a difficult place to uncover information. You see, the Varanians are a very proud people. They don’t want help from any outside country. And they’re insulted if you offer it. They value their neutrality very highly. Just the same, we’ve been hearing rumors that something is up. I must ask you to keep this strictly confidential.”

Bert Young looked in turn at each of the boys, who nodded seriously.

“Good. Then I’ll share our suspicions with you. We have a feeling that Duke Stefan, the Regent, isn’t on the level. He’s the ruler until Prince Djaro is crowned, and maybe he doesn’t want Djaro crowned. Duke Stefan, the Prime Minister, and the entire Supreme Council — which is like our Congress — work hand in glove. We feel that together they may do something to prevent Djaro from becoming prince.

“Now,” Bert Young continued, “ordinarily that would be an internal political matter and this country would keep its hands off. But the rumours say Duke Stefan has something bigger in mind. And that’s as far as our information goes. We need to know what Stefan’s up to. Just maybe, if you’re living right there in the palace, you can find out for us. None of the rest of us can get close enough to the Varanians to learn the truth. Maybe Djaro knows something and is too proud to ask for help, but will tell you. Or maybe the others, thinking you’re just ordinary kids, will get careless and let something slip.

“Will you take the assignment?”

Bob and Pete waited for Jupiter, as head of the firm, to speak. Jupe thought for a moment, then he nodded.

“If what you want us to do is try to help Prince Djaro, we’ll do it,” he said. “That is, if our families will let us. But we told Djaro we’d be his friends and we won’t do anything to undermine him.”

“That’s what I wanted to hear!” Bert Young exclaimed. “One piece of advice. Don’t tell Djaro you know there’s something wrong. Get him to tell you, if possible. And don’t let anyone guess why you’re there. Almost all the Varanians are loyal to Djaro — they idolized his father, who was killed in a hunting accident eight years ago. And they don’t like Duke Stefan. But if they thought you were spying, even in a good cause, they’d raise a terrific uproar. So keep your eyes and ears open and your mouths shut.
