“Nothing of importance has happened,” Greta said aloud to Vincent Stearns as he came toiling up the slope. “At least not to us. It was just an accident. Florence fell over a flare and kicked it into the fire. We—”

“A fortunate accident I should say!” Percy O’Hara’s tone was full of meaning. “Far as we can tell, there’s something going on down there by that little lake that needs looking into. And now we have reinforcements.”

“Sounds like an adventure.” The young newspaper photographer’s face took on a look of unwonted animation. “I’ll turn reporter and get a scoop for my paper.”

“When we have finished you may not be in a mood for writing.” Percy O’Hara did not smile as he said this.

In as few words as possible he told the little they knew of the mysterious ones who came and went in a hydroplane and who uttered unearthly screams in the night. “We might as well get right down there and have the thing over with at once,” he added at the end. “I don’t like interfering any more than I like being interfered with. It has been more than a year since I went into voluntary exile up here.” He paused to look away at the forest and distant waters all aglimmer with the light of the moon.

“Voluntary exile,” Greta thought, “I wonder why? Can it have been anything very terrible that drove him into seclusion? He does not appear to fear being taken back.”

“I’ve been thankful for the solitude,” Percy went on. “But there are times when one has no right to be left alone. Those people down there appear to have forfeited that right.

“I have a light rifle,” he added. “Thought I might use it sometimes to kill rabbits if necessity demanded it. I’ve never used it.”

“I’ve a gun of a sort,” Vincent added his bit. “I have a notion that persuasion is better than firearms, though. What say we get going? Young ladies—”

“We’re coming along,” Florence put in. “I’m strong as a man. I’ll do my part if need be, and Greta can be the nurse, in—in case—” She did not finish.
