"It's Cassidy, Pied-Bot! We can't lose that redheaded fox, can we ?" A good humored deviltry lay in his eyes, and Peter--looking up--thought for a moment his master was laughing.

Then Jolly Roger made a megaphone of his hands, and called very clearly out into the night.
"Ho, Cassidy! Is that you, Cassidy ?" Peter's heart was choking him as he listened.

He sensed a terrific danger.

There was no sound at the edge of the lake.

There was no sound anywhere.
