For a moment they were silent, listening for any sound that might break the stillness or rise above the gusts of wind, but although they strained their powers of hearing, no sound reached them. Then a flash of light out on the lake caught their attention. It lingered only a moment and then was gone, and after a brief interval, it came again.

“Somebody is running across the ice!” Barry and Mac said in chorus.

“Yes,” Kent agreed. “And they have a flashlight that they are turning on every once in a while. Wonder who they are?”

“I’ll bet they are the ones that yelled,” said Tim.

“Heading for Rake Island,” Barry observed.

“Maybe whoever is putting on all the funny business around the lodge hides away on Rake Island,” Kent suggested. “We ought to search that place one of these days.”

“We will,” Barry promised. He glanced toward the dark hunting lodge. “Which way did those shots come from?”

“I’d say from just behind the lodge,” Tim answered.

“Seemed that way to me,” Kent agreed. “They were mighty close to this cabin of ours.”

“Let’s go over there and see if we can find anything,” Barry suggested.
