Master Key: An Electrical Fairy Tale Founded Upon the Mysteries of Electricity e-bog

Rob is an electrical experimenter whose father encourages him and sees that he "e;never lacked batteries, motors or supplies of any sort."e; A "e;net-work of wires soon ran throughout the house"e;. He loses track of the elaborately interconnected wires, and trying to get a cardboard house to light up, he "e;experimented in a rather haphazard fashion, connecting this and that wire blindly and by guesswork, in the hope that he would strike the right combination."e; There is a bright flash, and a being who calls himself the Demon of Electricity appears. He tells Rob that he has accidentally "e;touched the Master Key of Electricity"e; and is entitled "e;to demand from me three gifts each week for three successive weeks."e; Rob protests that he does not know what to ask for, and the Demon agrees to select the gifts himself.
