"With some risk of death," said Laurance drily. "Well, yes. But that is a peculiarity of present-day fun. People love to play with death--it thrills them. However, if I am to hunt for the assassin of Sir Charles, I can't give much attention to aviation, and I repeat that I want money. Oceans of it."

"Would two thousand pounds suit you?"

"Rather. Only I'm not going to borrow from you, old man, thank you."

"I haven't that amount to lend," said Freddy, drily; "but you must have seen, if you read our very interesting paper, that our proprietor has offered a prize of two thousand pounds for a successful flight from London to York."

"A kind of up-to-date Dick Turpin, I suppose," laughed Dan, rising and stretching his long limbs. "Good, I'll have a shot, I may win."

"You will, if you use a Vincent machine."

"Vincent, Vincent? Where have I heard that name?"

"Everywhere if you know anything of the aviation world," snapped Laurance rather crossly, for at times Dan's indolence in acquiring necessary information annoyed him. "Solomon Vincent, who has been inventing airships and new-fangled aeroplanes for ever so long."

"Yes, yes! I remember now. He's a genius. Every one knows him." "Every one knows of him, except yourself; but no one knows him personally. He lives a secluded life up in Hillshire, on the borders of the moors, where he can find wide space for his experiments in aerial craft. I interviewed him a year ago, and--and----" Laurance blushed red. "Hullo, what's this?" asked Dan shrewdly. "Can it be that the inventor has a daughter fair?"

"A niece," retorted Laurance, recovering; "why shouldn't I be in love as well as you, Halliday? However, that doesn't matter."
