"Aussie whiz-kid and gadget-master Trevor Colby can turn a harmless toaster oven into a lethal weapon. He has extensive knowledge of explosives and a real knack for surprise. A practical joker at heart, Trevor takes as much delight in planning and setting a trap as he does in watching its perfect execution. Colby may be a little inexperienced but he catches on quickly."
