"There's a twist there which I can't seem to get straight," he admitted. "We'll have to watch Silva a little longer to find out what his game really is. Of course, it's just possible that he'd be glad to get rid of the girl, but that she really is obsessed by the idea of carrying out her father's wish. If that's the case, Silva is rather up a tree."

"That's where we'd better be getting," broke in Simmonds, who had taken out his watch and held it up to the light. "It's nearly twelve o'clock, and I don't want to miss the fireworks. Besides, you fellows don't gain anything by all this jawing. You've been at it for an hour, and you're more tangled up now than when you started. My motto with a case of this kind is just to sit quiet and watch it; and pretty soon the rat thinks the coast is clear, and pokes out his head, and you nab him."

"There's a good deal in that," agreed Godfrey, with a little laugh. "I admit that our arguing doesn't seem to lead anywhere. Come along," and he led the way out among the trees.

"Now take these fireworks," went on Simmonds, in a low tone, when we were sitting side by side on the limb. "I don't understand what they mean; but they must mean something. Am I laying awake nights worrying about them? Not me! I'm just going to keep on watching till I find out what the meaning is. I know you're a great fellow for theory and deduction, and all that sort of thing, Godfrey, and I know you've pulled off some mighty clever stunts; but, after all, there's nothing like patience."

"Yes—'it's dogged as does it,'" agreed Godfrey. "Patience is a great thing. I only wish I had more of it."

"It would be a good thing," assented Simmonds, candidly; and then we fell silent, gazing out into the darkness.

"Surely," said Godfrey, at last, "it must be twelve o'clock."

Simmonds got out his watch and flashed upon it a ray from his electric torch.

"Yes," he said, "it's four minutes after."

I felt Godfrey's hand stiffen on my arm.
