Larry glanced about apprehensively.

Then out of the night came the most weird, most demoniacal laugh any member of the Tramp Club ever had heard.
The boys sprang to their feet.
Other laughs, accompanied by shrieks, followed each other in quick succession.

The laughs seemed to come from all quarters.

It was difficult to say from just what particular point any one of them did come.
"Spooks!" yelled Larry Goheen, bolting toward the lake.

Billy caught and jerked him back.
"No, you don't," growled Billy.
