The girls walked along very quietly, treading on the grass so as to make no noise.

A slight mist was rising from the ground near the Abbey; in the rays of the moon it resembled a lake.

Everything, indeed, was altered.

The outline of the sumach bush was like a crouching tiger; the laburnum tassels waved like skeleton fingers.

It seemed a witching, unreal world.
Four rather scared girls crept along, clasping hands for moral support.
Each secretly would have been relieved to abandon the quest, but did not like to be the first to turn tail.
