"They got him into jail on a trumped-up charge," said Charlie. "And then they tried to keep Zara away from people who might learn the truth from her, and offer to supply the money he needed. In a little while they would have robbed him of all the profits of his invention."

"I'll finance it myself," said Richards, "and he can keep all of the profit."

Bessie's father and mother were far too glad to get her back to want to punish Maw Hoover, who was sincerely repentant. They could hardly find words enough to thank Eleanor and Dolly for their friendship, and to Charlie Jamieson their gratitude was unbounded.

But suddenly, even while the talk was at its height, there was a diversion. Billy Trenwith, his clothes torn, his hands chafed and bleeding, appeared on the dock.

"Good Heavens, Billy, I'd forgotten all about you!" said Charlie. "Where have you been?"

"How can you speak to him as a friend after the way he betrayed us?" asked Eleanor, indignantly, and Billy winced. But Charlie laughed happily.

"He didn't betray you," said he. "I cooked up this whole thing, just to catch Holmes red-handed, and he walked right into the trap. I told Billy not to tell you, because I wanted you to act so that Holmes wouldn't know it was a trick."

"He didn't trust me, though," said Billy, ruefully. "As soon as he had the girls, he tied me up and chucked me into his cellar so that I couldn't change my mind, he said. That's why I didn't meet you at the fort."

Eleanor, shamefaced and miserable, looked at him. Then, with tears in her eyes, she held out her hand to him.

"Can you ever forgive me?" she asked.
