CHAPTER II
The Storm
That shriek was the most fearful and uncanny sound the boys had ever heard. There was a diabolical malignance about it, like the scream of some blood-thirsty animal, yet there was no mistaking the fact that it was uttered by a human being.
As the quavering notes died away, the bare walls of the old house flung back the echoes so that the shriek seemed to be repeated again and again, but on a smaller scale.
The boys stared at one another, aghast. For a moment they were dumbfounded. Then Jerry muttered:
"I'm getting out of here!" and with that, he started for the door.
"Me too!" declared Biff Hooper, and Chet Morton followed him as he rushed for the doorway.
"What's the big idea?" asked Frank, standing his ground. "Let's stay and find what this is all about."
