"Then who did steal him?" asked Frank. "Don't be so mysterious."

"I want the matter to sink deep into your alleged minds!" was Ned's smiling rejoinder, "and that is the reason I'm drawing the explanation out. It is thought the boy was stolen by some one who came over the sea to do the job—some one never before in this country."

"I twig!" Jimmie declared, skipping about the room. "The stolen boy is next of succession to some measly old throne! What? And he was sent out here to get him out of the zone of danger, and now he's been nipped?"

The boys looked at Ned with redoubled interest. It had been interesting, the very idea of going into the mountains in quest of an abducted child, but the thought of going after a boy who would one day be a king! That was exciting indeed!

"I can't tell you who the boy is." Ned went on, "but I can tell you that he must be found! The Secret Service men at Washington have a pretty good idea as to who got him, and they believe the criminals are not above committing the crime of murder. In a certain sense, this boy is in the way in the old country!"

"Oh, they wouldn't kill a kid like that!" Jimmie asserted.

"Wouldn't they?" demanded Teddy Green. "If you read up on history, you'll soon find out whether ambitious men will murder children who stand in their way! I half believe the boy was murdered at the very moment he was taken!"

"He has been seen alive since that time," Ned responded. "This is
Thursday. He was taken on Monday, and was seen yesterday. Or a boy
believed to be the prince was seen yesterday, on a launch on the
Potomac river."

"Prince, eh?" cried Frank. "It is a prince, is it? Say, but won't dad be glad to hear about this? I'd like to write the headlines!"

"We may as well call him the prince," Ned laughed.
